This guide explains how to access your Home Assistant home automation box (which is located behind a dynamic IP address provided by your ISP) using a domain name with Infomaniak via the free DynDNS option and a free script (❓: help).

Introduction

• The integration you install acts as a messenger: it continuously monitors the IP address of your local network.
• As soon as it detects that your internet service provider has changed your IP address, it instantly sends a signal to Infomaniak.
• Infomaniak then updates your domain name (e.g., ha.domain.xyz) so that it points to the new IP address.

Prerequisites

• You must have a Home Assistant installation (e.g., on a Raspberry Pi 5) connected to the internet with a dynamic IP address.
• A dynamic DNS must have been created for the domain in question via the Infomaniak Manager (❓: help).
