Hello, I’ve just bought a few aqara devices, the first one I’ve tried to pair up is the Aqara Temperature and Humidity Sensor T1. In Z2mqtt it looks like it has but is not reporting anything back.
I did search and found Aqara WSDCGQ12LM control via MQTT | Zigbee2MQTT which mentions firmware updates for certain devices, the dates look older and not for the zbt-2.
I have removed and re- paired with debug on and it mostly looks fine to me except for the missing sensor values. The firmware version looks a little older.

Just wondering if anyone has the same setup and has the sensor working with ZBT-2 or should I just return these to the shop and get some different ones?
Thanks
