Actually, all thanks for that DTH should go to @johndoyle who made the original version and @1mb4k4 who updated it to work with the changes in SmartThings Hub Firmware 25.27.
I believe a “child” device needs to be created, but I would recommend reading this thread focused on the Aqara Wired Switch models, and maybe asking about issues there.
I am planning to buy one of this relay model myself, so I can also work on the DTH, but I won’t receive it until late June probably.
No, this cannot be changed. The hardware is “locked” to report based on temperature / humidity / pressure changes, not based on time.
The Aqara Temperature / Humidity Sensor hardware only reports when:
- the temperature changes more than 0.5° C, or
- humidity level changes more than 6%
- a change in atmospheric pressure (I cannot confirm the number)
