Missing Atmospheric Pressure Reading from T1 Sensor (Matter/Home Assistant)

​Hi everyone,
​I’m running a T1 Temperature/Humidity Sensor through a Hub S1 Plus, which is integrated into Home Assistant (HA) via Matter.

​I’ve noticed the atmospheric pressure reading is missing in HA, although temperature, humidity, and battery data are present.

​Is this a common problem, and does anyone know how to fix it?

I suspect that the air pressure reading isn’t being passed to Home Assistant via the Matter Bridge. I am experiencing the exact same behavior in my HA setup (pressure is missing).

However, if you connect the sensor directly via Zigbee2MQTT, the pressure value is correctly supported and exposed. You can verify the supported data points here: Aqara WSDCGQ12LM control via MQTT | Zigbee2MQTT
