Error whilst trying to set Aqara TRV temperature

[g0hww]

The problem

I was adjusting the radiator thermostat temperature and a notification relating to a constraint error was displayed. The set point temperature on the TRV did not correlate with the temperature I was dialling in to the thermostat widget,

I have only been using the new Aqara stuff for a few days and have it hooked in via the Matter beta integration. I am not very familiar with any of it yet.

What version of Home Assistant Core has the issue?

core-2023.12.1

What was the last working version of Home Assistant Core?

Unknown

What type of installation are you running?

Home Assistant OS

Could it be that this was just a one time error ? The device is complaining that you were trying to set something out of range. Probably the result of the device being out of sync with the value its communicating.

Hi. Thanks for considering my report.

Maybe that was the cause of the stack trace I posted, and I don't seem to be seeing that particular problem now.

However, I have avoided using HA to modify the set point temperature of the TRVs, as it pretty much always gets out of whack, with HA reporting a different set point to what ends up being reflected on the TRV's own display, which is always consistent with what is shown in Homekit, which runs straight from the Aqara M2 Hub.

If I use Apple Home to modify the TRV's set point temperature, HA updates immediately to match the new value, but if I try to modify the set point temp from HA, then things go awry.

I'm not experienced enough to know if this is really a Matter issue.

My hunch is that HA is somehow adjusting the set point temp with relative changes, rather than specifying an absolute value as the new set point temp, but I remain unconvinced that is really the case.

I have this very same device here on my testbench and its working fine. Are you using it with Fahrenheit or Celsius ?

Correction: I can reproduce it now but only when setting certain tresholds. I'll play with it some more.
