The Rain Sensor, when exposed to SmartThings via Matter, fails to report its wet/dry state. It only exposes entities for battery level and illuminance.
For comparison, the native Tuya app reports the status correctly: it shows as 'dry' when the sensor voltage is at 0mV, and 'wet' when the voltage is above 0mV.
I cannot see the humidity status displayed on the SmartThings interface, regardless of whether rain is detected or not.
I suspect this is a compatibility issue with SmartThings. Would you be able to compare it using HomePod mini, Home Assistant, etc., or seek further assistance on the SmartThings forum?
It's strange that it would be an issue with SmartThings; months ago, this rain sensor, when exported via Matter, correctly showed the rain status (dry, wet) in SmartThings.
If there's no other solution, I'll use this device paired directly with the SmartThings hub. I found a driver that displays luminosity and rain status—the most important entity on this device is detecting rain.
Thanks for your help with the other Tuya devices, which are working well.
