From a design perspective, the w600 thermostat is great. But from a functionality perspective, it’s a piece of crap. Will aqara support finally do something about it? @XT-XianTang

I can agree with that.
Its the currently best designed TRV on the marked.
Software is crap.
Also, iam curious about the 2 wire dc motor moving the Valve Pin.
I took one device apart and watched the hardware inside and figured out, there are only 2 wires going to the DC motor. i dont know how they track the position of the pin.
Other brands TRVs using stepper motors where they can exactly set the steps to know where the pin is.

Today it happened to me again that the thermostat in zigbee showed 0% opening but the radiator was heating. This control is useless !!!

Did you recalibrated it? I noticed the original Batteries are very very weak. After replacing the batterys, the shaft was driving much further and were closing the radiator properly.
Yes. After calibration, it was fixed. But I didn’t change the batteries. I just noticed that the radiator is heating even though it’s not. I can’t keep an eye on all the radiators like this.
