Home Assistant: Der ultimative Fernzugriff für dein Home Assistant und mehr !🚐

Introduction

This tutorial provides a comprehensive guide on setting up a secure remote connection to your Home Assistant using WireGuard on a V-Server in the cloud. The method is suitable for various scenarios, including accessing your Home Assistant from a camper, boat, or home network. By following these steps, you will ensure a secure and efficient connection to your smart home setup.

Step 1: Understanding the V-Server

• A V-Server, or virtual server, is a cloud-based server that allows you to run applications and services remotely.
• Benefits of using a V-Server:
  • Accessibility from anywhere with an internet connection.
  • Enhanced security through VPN configurations.
  • Flexibility for various network setups, including IPv4 and IPv6.

Step 2: Purchasing a V-Server

• Choose a cloud provider (e.g., Ionos) and select a V-Server plan that suits your needs.
• Current pricing and specifications can be checked on the provider's website.

Step 3: Basic Configuration of the V-Server

• Access your V-Server via SSH (Secure Shell):
  • Open a terminal on your computer.
  • Connect using the command:

    ssh username@your_server_ip
    

• Update and upgrade the operating system:

  sudo apt update
  sudo apt upgrade
  

Step 4: Setting Up Firewall on the V-Server

• Configure the firewall to enhance security:
  • Use UFW (Uncomplicated Firewall) to allow necessary ports for WireGuard and Home Assistant.

Step 5: Enabling IPv4 Forwarding

• Ensure that your server can forward IPv4 traffic:
  • Edit the sysctl configuration:

    sudo nano /etc/sysctl.conf
    

  • Uncomment or add the line:

    net.ipv4.ip_forward=1
    

  • Apply the changes:

    sudo sysctl -p
    

Step 6: Installing WireGuard on the V-Server

• Install WireGuard using the following command:

  sudo apt install wireguard
  

Step 7: Configuring WireGuard

• Create and edit the WireGuard configuration file:

  sudo nano /etc/wireguard/wg0.conf
  

• Add the following configuration, adjusting for your network specifics:

  [Interface]
  PrivateKey = your_private_key
  Address = 10.0.0.1/24
  
  [Peer]
  PublicKey = your_peer_public_key
  AllowedIPs = 10.0.0.2/32
  Endpoint = your_client_ip:51820
  

Step 8: Setting Up Client Devices

• Install WireGuard on your client device (e.g., laptop or mobile).
• Create a similar configuration file with the appropriate details for your client.

Step 9: Testing the Connection

• Verify that the traffic is correctly routed through the WireGuard tunnel.
• Use the command to check the connection status:

  sudo wg
  

Step 10: Hardening the Firewall

• After ensuring everything is working, finalize your firewall settings for maximum security.

Step 11: Integrating WireGuard with Home Assistant

• Install the WireGuard integration in Home Assistant:
  • Go to Configuration > Integrations > Add Integration.
  • Follow the prompts to set up WireGuard.

Step 12: Mobile Access via WireGuard

• Install the WireGuard app on your mobile device.
• Import your client configuration to access your Home Assistant remotely.

Step 13: Additional Configuration for Mobile Routers

• If using a mobile router (e.g., for campers), ensure the router is configured to connect to the V-Server.
• Manage tethering settings as needed for seamless connectivity.

Conclusion

By following these steps, you will establish a secure connection to your Home Assistant via WireGuard on a V-Server. This setup not only enhances security but also allows you to access your smart home from anywhere. For further improvements, consider exploring advanced routing configurations and additional security measures for your network.
