OVH IPv6 DynHost Updater for Home Assistant

This custom integration for Home Assistant allows you to automatically update your OVH DNS records with your current IPv6 address using OVH's DynHost service.

Features

• Automatic IPv6 address detection using Home Assistant's network API
• Periodic DNS record updates (every 15 minutes)
• Easy configuration through the Home Assistant UI
• Uses OVH's official DynHost service
• Supports AAAA (IPv6) records

Prerequisites

1. An OVH account with a registered domain
2. DynHost enabled for your domain
3. A DynHost username and password
4. The hostname you want to update
5. A working IPv6 connection

Installation

HACS (Recommended)

1. Open HACS in your Home Assistant instance
2. Click on "Integrations"
3. Click the three dots in the top right corner
4. Select "Custom repositories"
5. Add this repository URL: https://github.com/Elijaht-dev/ovh_ipv6
6. Select category: "Integration"
7. Click "Add"
8. Find "OVH IPv6 DynHost" in the integration list and install it

Manual Installation

2. Copy the custom_components/ovh_ipv6 folder to your Home Assistant's custom_components directory
3. Restart Home Assistant

Configuration

Setting up DynHost in OVH

1. Log into your OVH Control Panel
2. Navigate to your domain's DNS zone
3. Click on the "DynHost" tab
4. Create a new DynHost user by clicking "Manage access" and "Create an identifier"
5. Note down the username and password
6. Add a new DynHost record for the hostname you want to update

Setting up the Integration

1. In Home Assistant, go to Configuration > Integrations
2. Click the "+ ADD INTEGRATION" button
3. Search for "OVH IPv6 DynHost"
4. Enter your:
   • DynHost Username
   • DynHost Password
   • Hostname to update (e.g., "dynamic.example.com")

The integration will automatically:

• Detect your non-link-local IPv6 address
• Update your DynHost record every 15 minutes
• Retry on connection failures

Troubleshooting

Common Issues

• Invalid authentication credentials: Double-check your DynHost username and password
• Cannot connect: Verify your internet connection and that the DynHost service is accessible
• No IPv6 address detected: The integration searches for a non-link-local IPv6 address on all enabled network adapters. Ensure:
  • Your network has IPv6 connectivity
  • Your Home Assistant instance has a public IPv6 address
  • The network adapter is enabled and properly configured

Logs

To view the integration's logs, add this to your configuration.yaml:

logger:
  default: info
  logs:
    custom_components.ovh_ipv6: debug
