Home Assistant on VPS: Installation, Configuration, and Maintenance

Home Assistant on a VPS is an optimal solution for deploying a powerful, centralized, and fully controlled smart home system with remote access, providing high performance and flexibility for any automation scenarios.

What is Home Assistant and why deploy it on a VPS?

Home Assistant (HA) is a powerful open-source platform designed for smart home automation. It allows you to unify thousands of different devices and services from various manufacturers under a single control, creating complex interaction scenarios and providing a single user interface to control the entire infrastructure. From light bulbs and thermostats to security cameras and motion sensors, Home Assistant can manage almost anything that has an API or is supported by one of its numerous integrations.

Deploying Home Assistant on a VPS (Virtual Private Server) gives the user an unprecedented level of control, security, and flexibility compared to off-the-shelf cloud solutions or local devices like Raspberry Pi. Unlike proprietary systems, which often rely on manufacturer cloud services and can be shut down at any time, Home Assistant installed on your own VPS is entirely yours. This means you control the data, access, and functionality without worrying about third-party privacy policies or potential server outages.

Key Advantages of Home Assistant

• Full Control and Privacy: Your data remains on your server, not in a third-party cloud. You decide what and how to automate, without restrictions or surveillance.
• Broad Compatibility: Home Assistant supports over 2500 integrations, allowing you to connect devices from Apple HomeKit, Google Assistant, Amazon Alexa, Zigbee, Z-Wave, Tasmota, ESPHome, and many others.
• Flexibility and Customization: From graphical dashboards to complex automations in Python (via AppDaemon) or Node-RED – Home Assistant provides tools to implement any idea. You can customize the interface, logic, and appearance of the system to your needs.
• Active Community: A huge community of developers and users constantly creates new integrations, add-ons, and provides assistance in solving problems.
• Local Operation: Most of the functionality can work entirely locally, without the need for internet access, which increases reliability and response speed.

Why a VPS for Home Assistant?

While Home Assistant can be installed on a Raspberry Pi or another mini-computer, hosting it on a VPS offers several significant advantages, especially for advanced users and those seeking maximum reliability and performance:

• Reliability and 24/7 Availability: VPS servers are hosted in professional data centers with redundant power, cooling, and high-speed communication channels. This ensures stable Home Assistant operation without interruptions, unlike home equipment which is susceptible to power outages and internet connection issues.
• Remote Access Without Complications: By deploying Home Assistant on a VPS, you get direct access to it from anywhere in the world via the internet, without the need to port forward on your home router or use complex VPN solutions. This simplifies remote access setup and enhances security.
• Scalability: As your smart home ecosystem grows and automations become more complex, you can easily increase your VPS resources (CPU, RAM, disk space) without migration or hardware replacement. This is a key advantage over single-board computers, where an upgrade often means buying a new device.
• Performance: Modern VPS servers use powerful processors and fast NVMe drives, providing significantly higher performance compared to a Raspberry Pi. This is critical for large installations with many integrations, historical data, and complex automations. Fast system response and instant interface loading significantly improve the user experience.
• Security: VPS providers ensure basic infrastructure security. You can also configure a firewall, VPN, intrusion detection systems, and other protective measures to maximize the security of your smart home system from external threats.
• Energy Saving: Instead of a constantly running home server consuming electricity, you utilize data center resources, which can be more energy-efficient and environmentally friendly in the long run, and also reduces electricity bills.

Thus, Home Assistant on a server is not just a way to run the platform, but an entire strategy for building a reliable, secure, and scalable smart home system that will serve you for many years.

What are the system requirements for Home Assistant on a server?

Defining the optimal system requirements for Home Assistant on a VPS is a key step towards stable and productive operation. Minimum requirements can be misleading, as the actual load heavily depends on the number of integrated devices, the complexity of automations, the volume of data collected, and the add-ons used.

Basic Resource Requirements

For comfortable use of Home Assistant self-hosted on a VPS, the following basic parameters are recommended. These figures represent a starting point and can be adjusted based on your plans.

• Processor (CPU):
  • Minimum: 1 vCPU with a clock speed of 2.0 GHz or higher. This is sufficient for a very modest installation with a few dozen devices and simple automations.
  • Recommended: 2 vCPU. Provides better interface responsiveness, allows processing more integrations, and executing more complex scripts without delays.
  • For large installations: 4+ vCPU. Necessary if you plan to use many cameras with video processing, resource-intensive add-ons (e.g., Frigate for object recognition), or actively work with large volumes of historical data.
• Random Access Memory (RAM):
  • Minimum: 2 GB. Home Assistant itself can consume from 500 MB to 1 GB RAM in idle mode. The remaining volume is needed for the operating system, Docker, and any other processes.
  • Recommended: 4 GB. This is the sweet spot for most users. It allows running Home Assistant, several popular add-ons (MariaDB, Mosquitto, Nginx Proxy Manager), and maintaining sufficient headroom for peak loads.
  • For large installations: 8+ GB. If you actively use a database for history storage, run many additional services in Docker, process video, or plan for long-term system expansion.
• Disk Space:
  • Minimum: 20 GB NVMe SSD. For the operating system itself, Docker, and a basic Home Assistant installation with a small amount of data. It is highly recommended to use NVMe SSD due to high read/write speeds, which is critical for the Home Assistant database.
  • Recommended: 40-60 GB NVMe SSD. Will allow storing more historical data, logs, backup snapshots, and installing additional add-ons without worrying about free space. Home Assistant actively writes to the database, so a fast disk significantly improves performance.
  • For large installations: 80+ GB NVMe SSD. If you plan to store video recordings from cameras, use Home Assistant as a central node for many sensors with high data recording frequency, or simply want a large reserve.
• Network Bandwidth:
  • Minimum: 100 Mbps. For interaction with smart devices, remote access, and updates.
  • Recommended: 1 Gbps. Standard for most modern VPS providers, ensures fast access to the interface and efficient operation with cloud integrations.

OS Selection Considerations for Home Assistant VPS

The choice of operating system for Home Assistant VPS also plays a role. We recommend using lightweight Linux distributions oriented towards server use:

• Ubuntu Server (LTS): The most popular choice. Features good documentation, a large community, and stability. It is recommended to use LTS (Long Term Support) versions for long-term support and fewer sudden changes.
• Debian: Known for its stability and minimalism. An excellent choice for those who prefer a "cleaner" system.
• AlmaLinux/Rocky Linux: Free alternatives to CentOS, offering enterprise-grade stability. Good for those accustomed to RHEL-like systems.

For this article, we will use Ubuntu Server 22.04 LTS, as it is the most common and well-supported option.

It's important to remember that these requirements apply to Home Assistant Core or Container installations. If you plan to use Home Assistant OS (HassOS) or Home Assistant Supervised, the requirements might be slightly higher due to the overhead of the OS itself and the Supervisor.

How to prepare a VPS for Home Assistant installation?

Before proceeding with Home Assistant installation, you need to properly prepare your VPS. This includes basic security configuration, system updates, and installing necessary components such as Docker.

Initial VPS Setup and Security

After gaining access to your VPS (usually via SSH), first perform the following steps:

1. System Update:

   Always start by updating the package database and installed packages to get the latest security fixes and new features.

   sudo apt update && sudo apt upgrade -y

2. Creating a new user with limited privileges:

   Working as the root account is insecure. Create a new user and grant them sudo privileges.

   sudo adduser valebyteuser
   sudo usermod -aG sudo valebyteuser

   After creating the user, exit the root session and log in as the new user.

   exit
   ssh valebyteuser@your_vps_ip

3. Firewall Configuration (UFW):

   Enable the firewall and allow only necessary ports. To start, this includes SSH (port 22) and HTTP/HTTPS (ports 80/443). Home Assistant defaults to port 8123.

   sudo ufw allow OpenSSH
   sudo ufw allow http
   sudo ufw allow https
   sudo ufw allow 8123/tcp
   sudo ufw enable

   Check the firewall status:

   sudo ufw status

   Ensure everything is allowed correctly. If you use a different port for SSH, allow that instead of 22.

4. Time Zone Configuration:

   The correct time zone is important for automations and logging to work correctly.

   sudo timedatectl set-timezone Europe/Moscow # Replace with your time zone
   timedatectl

Installing Docker and Docker Compose

Home Assistant Docker is the recommended deployment method, providing isolation, ease of updates, and portability. Docker Compose significantly simplifies container management.

1. Install Docker Engine:

   Install Docker by following the official documentation. This ensures you get the latest versions and correct configuration.

   # Remove old Docker versions (if any)
   for pkg in docker.io docker-doc docker-compose docker-compose-v2 podman-docker containerd runc; do sudo apt remove $pkg; done
   
   # Install necessary packages
   sudo apt update
   sudo apt install ca-certificates curl gnupg
   
   # Add Docker's official GPG key
   sudo install -m 0755 -d /etc/apt/keyrings
   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg
   sudo chmod a+r /etc/apt/keyrings/docker.gpg
   
   # Add the Docker repository
   echo \
     "deb [arch="$(dpkg --print-architecture)" signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
     "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
     sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
   
   # Install Docker Engine
   sudo apt update
   sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

2. Add user to the docker group:

   To run Docker commands without sudo, add your user to the docker group. After this, you need to log out and log back into your SSH session.

   sudo usermod -aG docker ${USER}
   exit

   After logging in again, verify the Docker installation:

   docker run hello-world

   If you see the message "Hello from Docker!", then the installation was successful.

Your VPS is now ready for Home Assistant deployment.

Step-by-step Home Assistant installation on VPS via Docker Compose

Now that the VPS is prepared, we can proceed with Home Assistant installation using Docker Compose. This method allows for easy management of configuration, dependencies, and provides simple updates.

Creating the project structure and Docker Compose file

To begin, let's create a directory where all Home Assistant files will be stored, including configuration and the Docker Compose file.

1. Creating a directory for Home Assistant:

   Create the main directory and a subdirectory for Home Assistant configuration. This will allow easy management of data and backups.

   mkdir -p ~/homeassistant/config

2. Creating the docker-compose.yml file:

   In the main directory ~/homeassistant, create a docker-compose.yml file. This file will describe how Docker should run the Home Assistant container.

   nano ~/homeassistant/docker-compose.yml

   Insert the following content:

   version: '3'
   services:
     homeassistant:
       container_name: homeassistant
       image: "ghcr.io/home-assistant/home-assistant:stable"
       volumes:
         - ./config:/config
         - /etc/localtime:/etc/localtime:ro
       environment:
         - TZ=Europe/Moscow # Replace with your time zone
       restart: unless-stopped
       privileged: true # May be required for some USB devices (e.g., Zigbee sticks). If not used, can be removed.
       network_mode: host # Allows Home Assistant to discover devices on the VPS's local network, if necessary.
                          # If you don't want to use host mode, you can use a bridge network and port forward:
                          # ports:
                          #   - 8123:8123
                          #   - 5353:5353/udp # For mDNS discovery
   

   Explanation of docker-compose.yml:

   • version: '3': Specifies the Docker Compose syntax version.
   • homeassistant: The name of your service.
   • container_name: homeassistant: Gives the container an easily recognizable name.
   • image: "ghcr.io/home-assistant/home-assistant:stable": Points to the official Home Assistant image. The stable tag ensures you always get the latest stable version.
   • volumes:: Defines mounted volumes.
     • ./config:/config: Mounts your local directory ~/homeassistant/config to the /config directory inside the container. All Home Assistant configuration files, the database, and add-ons will be stored here. This is critically important for data persistence during updates or container recreation.
     • /etc/localtime:/etc/localtime:ro: Synchronizes the container's time zone with the host system's time zone. :ro means "read-only".
   • environment:: Sets environment variables.
     • - TZ=Europe/Moscow: Sets the time zone inside the container. Make sure it matches your VPS's time zone.
   • restart: unless-stopped: The container will automatically restart if it stops for any reason (crash, VPS reboot), unless you stopped it manually.
   • privileged: true: Grants extended privileges to the container. This may be necessary if you plan to connect USB devices (e.g., Zigbee/Z-Wave sticks) directly to the VPS and pass them into the container. If you do not plan to use USB devices, you can remove this line for increased security.
   • network_mode: host: The container uses the host system's network stack. This simplifies device discovery on the VPS's local network (if your VPS is on the same network as smart devices, which is rare for cloud VPS) and allows Home Assistant to directly use host ports. If your VPS is not on the same local network as smart home devices, and you plan external access, you can use bridge mode and explicitly port forward 8123 (ports: - "8123:8123"). For most Home Assistant on a server installations, especially if you plan to use a reverse proxy, bridge mode is sufficient.

Starting Home Assistant and initial setup

After creating the docker-compose.yml file, you are ready to launch Home Assistant.

1. Starting the Home Assistant container:

   Navigate to the ~/homeassistant directory and run Docker Compose:

   cd ~/homeassistant
   docker compose up -d

   The up -d command will start the container in detached mode. Docker will download the Home Assistant image (if not already local) and start the container.

   Check the status of running containers:

   docker ps

   You should see the homeassistant container in the list with a status of Up.

   View Home Assistant logs (for debugging):

   docker compose logs -f homeassistant

2. Initial access to Home Assistant:

   Once the container starts (this may take a few minutes on the first run, as Home Assistant initializes the database and loads components), you will be able to access the web interface.

   Open a web browser and go to: http://your_vps_ip:8123. You will see the Home Assistant welcome screen, where you will be prompted to create an administrator account. Set a name, password, and other initial settings.

3. Further configuration:

   After creating an account, you will enter the main Home Assistant interface. The system will automatically try to discover some devices on your local network (if you are using network_mode: host and have compatible devices on the same subnet as your VPS, which, again, is rare for a cloud VPS). You can start adding integrations, devices, and creating your first automations.

   Remember that for most smart devices located in your home, you will either need to install additional software on your home router/computer (e.g., an MQTT broker that forwards traffic to the VPS), or use cloud integrations. If you want to integrate Zigbee/Z-Wave devices located in your home, you will either need to use a USB stick with USB over IP forwarding, or run a local gateway (e.g., Zigbee2MQTT on a Raspberry Pi) and connect it to Home Assistant on the VPS.

Your basic Home Assistant installation on a VPS is complete. The next step will be to configure secure access via a domain name and HTTPS.

Configuring Secure Access: Reverse Proxy (Nginx/Caddy) and HTTPS for Home Assistant

Direct access to Home Assistant via port 8123 using an IP address is neither secure nor convenient. To ensure secure access via a domain name and HTTPS (encryption), you need to configure a reverse proxy server. This will allow you to use an address like https://homeassistant.your_domain.com.

Choosing and installing a reverse proxy

A Reverse Proxy accepts incoming requests on standard ports (80 for HTTP, 443 for HTTPS) and redirects them to the internal Home Assistant port (8123). We will consider two popular options: Nginx and Caddy.

Option 1: Nginx (traditional and powerful)

Nginx — is a high-performance web server and reverse proxy, widely used in the industry. It requires manual configuration but provides maximum flexibility.

1. Install Nginx:

   sudo apt update
   sudo apt install nginx -y

   Allow Nginx in the firewall, if you haven't already:

   sudo ufw allow 'Nginx Full'
   sudo ufw delete allow 8123/tcp # Now access via 8123 will be local only

2. Configure Nginx for Home Assistant:

   Create a new configuration file for your domain (e.g., homeassistant.your_domain.com):

   sudo nano /etc/nginx/sites-available/homeassistant.conf

   Insert the following content, replacing homeassistant.your_domain.com with your actual domain:

   server {
       listen 80;
       listen [::]:80;
       server_name homeassistant.your_domain.com;
   
       location / {
           proxy_pass http://localhost:8123; # Or http://homeassistant:8123 if HA is in a Docker bridge network
           proxy_set_header Host $host;
           proxy_set_header X-Real-IP $remote_addr;
           proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
           proxy_set_header X-Forwarded-Proto $scheme;
   
           # WebSocket support
           proxy_http_version 1.1;
           proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";
       }
   }
   

   Note: If you used network_mode: host for Home Assistant, then localhost:8123 will work. If you used a Docker bridge network and named the container homeassistant, you can use http://homeassistant:8123 to refer to the container by its name within the Docker network.

3. Activate configuration and restart Nginx:

   sudo ln -s /etc/nginx/sites-available/homeassistant.conf /etc/nginx/sites-enabled/
   sudo nginx -t # Syntax check
   sudo systemctl restart nginx

   Now Home Assistant should be accessible via HTTP through your domain.

Option 2: Caddy (modern and simple)

Caddy — is a modern web server that automatically manages Let's Encrypt SSL certificates. This makes it incredibly simple to configure for HTTPS.

1. Install Caddy:

   Caddy can be installed from the official repository:

   sudo apt install -y debian-keyring debian-archive-keyring apt-transport-https
   curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
   curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
   sudo apt update
   sudo apt install caddy -y

   Allow Caddy in the firewall:

   sudo ufw allow 'Caddy'
   sudo ufw delete allow 8123/tcp

2. Configure Caddyfile for Home Assistant:

   Create or edit the file /etc/caddy/Caddyfile:

   sudo nano /etc/caddy/Caddyfile

   Remove all existing lines and insert the following, replacing homeassistant.your_domain.com with your domain:

   homeassistant.your_domain.com {
       reverse_proxy localhost:8123 # Or homeassistant:8123 if HA is in a Docker bridge network
       # Additional headers for WebSocket
       header {
           Host {host}
           X-Real-IP {remote_ip}
           X-Forwarded-For {remote_ip}
           X-Forwarded-Proto {scheme}
           Upgrade {http_request_header.Upgrade}
           Connection {http_request_header.Connection}
       }
   }
   

3. Restart Caddy:

   sudo systemctl restart caddy
   sudo systemctl enable caddy # For autostart after reboot

   Caddy will automatically obtain and install a Let's Encrypt SSL certificate, and your Home Assistant will be accessible via HTTPS.

Obtaining an SSL certificate with Let's Encrypt and automation (for Nginx)

If you chose Nginx, you will need to manually obtain an SSL certificate using Certbot.

1. Install Certbot:

   sudo apt install certbot python3-certbot-nginx -y

2. Obtain the certificate:

   Run Certbot and follow the instructions. It will automatically configure Nginx for HTTPS.

   sudo certbot --nginx -d homeassistant.your_domain.com

   Certbot will ask if you want to force HTTP to HTTPS redirection. It is recommended to choose "2: Redirect".

3. Automatic certificate renewal:

   Certbot automatically creates a cron job to renew certificates before they expire. You can check the automatic renewal process like this:

   sudo certbot renew --dry-run

   If there are no errors, everything is configured correctly.

Now your Home Assistant on VPS is accessible via a secure HTTPS connection through your domain. This is critically important for security, especially if you plan to use remote access or integrate Home Assistant with voice assistants.

Home Assistant Maintenance: Backup and Update Strategies

Regular maintenance of Home Assistant on a VPS is key to stable and secure operation. This includes creating backups and timely system updates.

Automatic Home Assistant Backups on VPS

Home Assistant data (configuration, database, logs) is stored in the directory we mounted as a volume (~/homeassistant/config). Regularly backing up this directory is a critically important task.

Simple Backup Script

You can create a simple script to archive the configuration and schedule its execution using cron.

1. Creating the backup script:

   Create a backup_homeassistant.sh file in your home directory:

   nano ~/backup_homeassistant.sh

   Insert the following content:

   #!/bin/bash
   
   # Home Assistant configuration directory
   CONFIG_DIR="/home/valebyteuser/homeassistant/config" # Ensure the path is correct
   BACKUP_DIR="/home/valebyteuser/backups/homeassistant" # Directory for storing backups
   TIMESTAMP=$(date +"%Y%m%d_%H%M%S")
   BACKUP_FILE="${BACKUP_DIR}/homeassistant_config_${TIMESTAMP}.tar.gz"
   
   # Create backup directory if it doesn't exist
   mkdir -p "${BACKUP_DIR}"
   
   echo "Starting Home Assistant config backup..."
   
   # Stop Home Assistant container before backup to ensure DB integrity
   docker compose -f /home/valebyteuser/homeassistant/docker-compose.yml stop homeassistant
   
   # Create configuration archive
   tar -czvf "${BACKUP_FILE}" -C "${CONFIG_DIR}" .
   
   # Start Home Assistant container
   docker compose -f /home/valebyteuser/homeassistant/docker-compose.yml start homeassistant
   
   echo "Backup created: ${BACKUP_FILE}"
   
   # Delete old backups (e.g., keep the last 7 days)
   find "${BACKUP_DIR}" -type f -name "homeassistant_config_*.tar.gz" -mtime +7 -delete
   echo "Old backups cleaned up."
   

2. Make the script executable:

   chmod +x ~/backup_homeassistant.sh

3. Schedule backup with Cron:

   Open crontab for your user:

   crontab -e

   Add a line for daily backup, for example, at 3:00 AM:

   0 3 * * * /home/valebyteuser/backup_homeassistant.sh >> /var/log/homeassistant_backup.log 2>&1

   This line will run the script daily at 3 AM and write the output to a log file.

Using specialized backup tools

For more advanced backup scenarios, especially if you want to store backups on remote storage, consider tools like Restic. Restic supports incremental backups, encryption, and sending to various cloud storage providers (S3, SFTP, Backblaze B2, etc.). Its integration will require more complex configuration but will provide a high level of reliability and security.

Home Assistant and Docker Container Update Procedure

Updating Home Assistant and the underlying Docker system is an important part of maintenance.

1. Updating the VPS operating system:

   Regularly update your OS to receive the latest security fixes and performance improvements.

   sudo apt update && sudo apt upgrade -y
   sudo apt autoremove -y # Remove unnecessary packages
   sudo reboot # Reboot if kernel or system components were updated

2. Updating Docker Engine:

   Docker Engine is updated along with other packages during sudo apt upgrade if you installed it from the official Docker repository.

3. Updating Home Assistant:

   Updating the Home Assistant container to a new stable version is very simple thanks to Docker Compose:

   cd ~/homeassistant
   docker compose pull homeassistant # Download the latest stable image version
   docker compose up -d homeassistant # Stop the old container, start a new one with the updated image
   

   After executing these commands, Docker Compose will first download the new ghcr.io/home-assistant/home-assistant:stable image, then stop and remove the old homeassistant container, and then create and start a new container with the same name, using the new image and existing data in the ./config volume.

   It is always recommended to check the logs after an update to ensure there are no errors:

   docker compose logs -f homeassistant

   It is also useful to consult the official Home Assistant blog before updating to be aware of any critical changes that might require manual configuration.

Regularly performing these procedures will ensure the stability, security, and currency of your Home Assistant self-hosted system.

Which VPS configuration is optimal for Home Assistant under real load?

Choosing the right VPS for Home Assistant is a balance between performance, cost, and your needs. A VPS that is too weak will be slow, and one that is too powerful will be an overpayment. Let's consider a few typical usage scenarios and recommended configurations.

Usage Scenarios and Recommended Configurations

It's important to understand that the "optimal" VPS for Home Assistant on a server depends on your specific tasks. Here are a few scenarios:

1. Light Scenario (Beginner user, basic automations):
   • Description: A few dozen devices (light bulbs, smart plugs, temperature sensors), simple automations, minimal add-ons (e.g., only Mosquitto MQTT). History is not stored for long.
   • Load: Low.
2. Medium Scenario (Advanced user, moderate automations):
   • Description: Up to 100-150 devices, more complex automations, active use of a database for history, several add-ons (MariaDB, Node-RED, InfluxDB), integration with voice assistants, possibly a few cameras without active video processing.
   • Load: Medium.
3. Heavy Scenario (Expert, complex systems):
   • Description: Hundreds of devices, dozens of complex automations, active use of Frigate (video processing from cameras), a large number of add-ons, extensive history storage, integration with external services, possibly running other Docker containers on the same VPS (e.g., Netdata for monitoring, Filebrowser for file management).
   • Load: High.

Below is a table with recommended VPS configurations for each scenario. Prices are approximate and may vary among different providers, but give an idea of the cost range.

Usage Scenario	vCPU (cores)	RAM (GB)	NVMe SSD (GB)	Bandwidth	Approx. Price/Month
Light (Beginner)	1	2	20-40	100 Mbps - 1 Gbps	$5 - $10
Medium (Advanced)	2	4	40-80	1 Gbps	$10 - $25
Heavy (Expert)	4+	8+	80-200+	1 Gbps	$25 - $50+

Extending Functionality and Enhancing Security for Home Assistant Self-Hosted

Installing Home Assistant on a VPS is just the beginning. The platform offers immense opportunities to extend functionality and enhance the security of your smart home system.

Integrations and Add-ons

Home Assistant has a rich ecosystem that allows you to significantly expand its capabilities:

• Databases: By default, Home Assistant uses SQLite, but for larger installations, it is recommended to switch to MariaDB/PostgreSQL. You can easily deploy them in Docker containers on the same VPS to improve performance and reliability of history storage.
• MQTT Broker (Mosquitto): Extremely useful for integrating DIY devices (ESP32/ESP8266 with Tasmota/ESPHome) and many other smart home devices that exchange data via the MQTT protocol.
• Node-RED: A visual tool for creating complex automations. It allows building logic by "dragging and dropping" blocks, which simplifies the development and debugging of complex scenarios.
• Frigate: A powerful video analytics system that uses Coral AI (TPU) for object recognition in video streams from cameras. If you plan to actively work with cameras, Frigate on a powerful VPS with a GPU (if available) or a TPU accelerator will become an indispensable tool.
• HomeKit Controller: Allows Home Assistant to discover and control HomeKit devices, as well as present its own devices as HomeKit accessories for control via iPhone/iPad.
• Dashboards: In addition to the standard Lovelace UI, you can use alternative dashboards, such as Dwains Dashboard, for a more customized and aesthetic interface.

Many of these add-ons can also be run in Docker containers on your VPS, which highlights the flexibility of the Home Assistant Docker approach.

Additional Security Measures

Although we have already configured HTTPS and a firewall, there are a few more steps to enhance the security of your Home Assistant self-hosted:

• Two-Factor Authentication (2FA): Be sure to enable 2FA for all Home Assistant accounts. This will significantly complicate unauthorized access, even if an attacker learns your password. Home Assistant supports TOTP applications (Google Authenticator, Authy).
• Fail2ban: Install Fail2ban on your VPS. It will automatically block IP addresses that make many failed login attempts via SSH or to the Home Assistant web interface (if configured for Nginx/Caddy).
• VPN Access: Instead of direct access to Home Assistant from the internet, consider setting up a VPN server on your VPS (e.g., WireGuard or OpenVPN). This will allow you to connect to your home network via an encrypted tunnel, and then access Home Assistant, which is a more secure approach.
• Updates: As mentioned earlier, regularly update the OS, Docker, and Home Assistant itself. This closes known vulnerabilities.
• API Access Restriction: If you use any API keys or tokens for integrations, ensure their permissions are limited to the necessary minimum.
• Monitoring: Use monitoring tools such as Netdata to track CPU, RAM, disk, and network traffic on your VPS. This will help identify anomalies that may indicate performance issues or attempted breaches.
• Brute-force protection for admin access: Solutions like Authelia or Authentik can be used, which integrate with a reverse proxy and add an additional layer of authentication before accessing the Home Assistant web interface.

Implementing these measures will allow you to create not only a functional but also a maximally secure smart home system on your VPS.

Conclusion

Deploying Home Assistant on a VPS is a powerful and flexible solution for creating a fully controlled smart home system, providing high performance and reliability. By following the step-by-step instructions for installation via Docker Compose, configuring secure access using a reverse proxy, and performing regular maintenance, you will get a stable platform for all your automation needs.

For optimal Home Assistant performance, we recommend choosing a VPS with 2-4 vCPU, 4-8 GB RAM, and a fast NVMe SSD of 40 GB or more, which can be found in Valebyte.com's tariff plans.

Such a configuration will ensure not only comfortable use but also sufficient headroom for future expansion of your smart home system.
