# Home Assistant

## We Use Standard MQTT to Home Assistant

Currently these devices support Home Assistant via MQTT:

* **Motion/Presence Sensor**: eMotion, eMotion Max, eMotion Pro, eMotion Ultra
* T**emperature Humidity Sensor**: eTHS
* **IR Universal Remote**: eRemote

You don't need to add any specific integration in Home Assistant! 

Just make sure you have MQTT service in Home Assistant and configured ready for use.

## Configure MQTT in LinknLink App

In LinknLink App, enter device page. Click the "..." icon in the top-right corner, then select "MQTT Connection." Enter the required information based on your MQTT server settings and click "Save". Reopen "MQTT Connection" to verify that the status shows "Connected".

## Use Device in Home Assistant

Once MQTT is connected, the device will automatically appear in your Home Assistant with its status synced in real-time. If the device is an IR universal remote, all virtual IR devices with their available buttons will be synced and ready for use.&#x20;
