I have been buying thermostats one after the other since November 2022. At the beginning of this year, the first thermostat broke, and recently the second one broke.
In my opinion, the problem is that the motor is too powerful and the calibration does not work well, so the motor does not stop in time. In other words, when the valve is closed, the motor generates too much tension on the thermostat/housing. This makes it difficult or even impossible to operate the thermostat manually.
In some cases, constant pressure is also exerted on the rotary knob, which causes the thermostat to constantly switch to pairing mode.
In my defective thermostats, the pressure was so strong that the internal anchorage broke.
Support always replaced the defective devices without any problems, but the underlying problem remains unresolved. In other words, new firmware needs to be released to optimize the calibration. Or am I wrong?
thank you for your feedback. I probably didn’t search thoroughly enough. It’s “good” to hear that I’m not alone with this problem, but it seems to me that the developers haven’t addressed it yet.
In my opinion, it can’t be a solution that the customer has to replace screws or the housing (with self-printed ones)
A small fix in the firmware would probably help:
Less power to the motor
Stop the motor earlier when it encounters resistance (calibration)
If anyone would like my defective devices, please feel free to contact me (shipping to Germany or pickup possible).
I don’t think, that this is a firmware issue. The screws were just too big, or the holes too small.
I believe, a firmware update, that would stop the motor when it encounters resistance would make the thermostats useless, as the motor it always encounters resistance when it tries to close the valve
