Yes I have read about Zigbee2MQTT. But I don’t favor this solution for the same reasons @chris mentions in this thread:
- it relies on a specific coordinator device (that I don’t own and don’t intend to buy) with a custom firmware (I don’t want to have a flash a microcontroler on such a device)
- the MQTT side does conceptually nothing special on the Zigbee side of things. I guess that the zibgee-sheperd/custom firmware combination does something that prevents the Aqara devices from going to sleep. But this could theoretically be implemented in openHAB as well.
