since yesterday I have two Aqara Radiator Thermostats whoch are now tied to my HA via a SONOFF Zigbee stick, which works pretty fine.
But the thermostats are not showing any information about the battery levels. Is this by intention or is this a bug in the zigbee intregration or even in the thermostats?
As far as i know the Aqara TRV is not fully supported in ZHA yet. If you dont know about this, here is a useful resource to check support of zigbee devices. I am using Z2MQTT and can see the battery state of my thermostats, maybe also consider switching to Z2M for larger device and functionality support.
