<mark style="color:red;">**IMPORTANT**</mark>: If you don't see the MQTT connection setting in the menu, it means you're using the eHome model, not eHome HA. However, you can easily upgrade the firmware to convert it to eHome HA. Please refer to [update-from-ehome](https://kb.linknlink.com/kb/smart-home-devices/ehome-ha/update-from-ehome "mention")

### 7. CONFIGURE MQTT FOR HA

Return to the eHome HA 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". Re-enter "MQTT Connection" to verify that the status shows "Connected".

### 8. DISCOVER DEVICES AND CONTROL IN HA

Once MQTT is connected, the added RF device will automatically appear in your Home Assistant, with the available buttons synced and ready for use. You can now use the RF device in HA for complete local automations.

**NOTE**: Once the MQTT connection is set up, any newly added RF devices will be automatically synced to Home Assistant without the need for additional configuration.
