versatile_thermostat: radiator valve stuck in loop ("changed to heat / turned off / … triggered by service Climate: Set HVAC mode") until HA reboot
Version of the custom_component
I’m running the latest VTherm version 3.5.2, all other integrations and HA have no available updates either.

Describe the bug
After creating a Virtual Thermostat for a Eve Thermo Homekit Device and a simple thermostat lovelace card, when switching the preset in the UI the thermostat valve started turning on/off/on/off/on/off as fast as it could, until its battery was nearly empty and I rebooted HA. Other than the reboot of HA I couldn’t find anything to stop this loop.
As this happened to me a week ago with a different virtual thermostat, this seems to be a more frequent issue than initially expected, at least in my setup.
Here’s everything I could find that might be relevant to debugging the issue. I might be able to reproduce it, it was just a very bad timing when it happened.

I just push the release ! 3.5.3 which officialize the fix.&
Thnak for the beer, I really appreciate. Cheers from France !
Great news: I cannot reproduce the issue anymore. Jean-Marc, thanks a lot for all your work. (I’ve actually bought you some beers a few days ago, I’m seeing a transaction on my Apple Pay, but you didn’t receive it. The support team is looking into what happened and will hopefully fix it on Monday)
Just q auick first “thumbs up”: I had no time to enable and look into the logs, but “my error” seems not to occur anymore with the beta version.
Here’s a log with debug set for the integration and info for everything else. It’s a minute long. Until about 15:55:22 I manually clicked and changed the target temp and switched heat/off a few times, then the loop started. Near the end of the log I disabled the underlying TRV: VTherm loop 231014.log
Ok, I got exactly the case (for @maia at least). This is a side effect of the #101 issue and the #113 issue that were released in the last version when the response of the underlying is slow.
The scenario is the following:
If response of the underlying is instantaneous, you don’t have this effect because the target temp of the underlying is equal to the target temp of the VTherm and nothing is done by VTherm.
Fixing this is tricky (without removing #110). I will to see with your logs if i can ignore the target of underlying when a manuel change have been made after. I’m sure I will have all the dates to do that.
In my case I can reproduce the behavior (if it’s the same) when clicking my Aqara Thermostat directly on the hardware 3x in a row, which is the sequence used to start a valve calibration. Seemingly this three fast clicks are interpreted somehow by VT and cause confustion.
Hmm, well clicking 6x in 3 seconds happens when you see the thermo is set to 21°C, you decide you want it warmer, so you click 3x the “+” to 22,5°C, then decide that it’s a waste of energy and you’ll revert back to 21°C, so you click 3x the “-”. Boom, 6 clicks in 3 seconds.
(And as mentioned, when doing this directly on the hardware itself or on the HA underlying thermostat device, it’s not an issue. Only when doing this in the VTherm device it is an issue.
Thanks for looking into it!
This will definitively helps me to reproduce to case (+ the logs)
Here’s a 900KB debug log of about 45 seconds time with a stuck loop which I triggered by quickly changing the temperature as described above. It has 137 occurrences of “Checking new cycle”, so 2-3 cycles per second: vtherm debug 231013.log.
Update, I think I can now reproduce the issue: The loop starts when changing the target temperature, the preset or the heating/off switch “too fast” in the control of the versatile thermostat device.
It doesn’t matter if I make the changes from a simple-thermostat card, from the lovelace UI or from the integration device overview. As soon as I make about 5 changes within 2-3 seconds, the loop starts. The loop can be stopped by disabling the underlying TRV device and reenabling it.
When making the same changes in the underlying TRV device, the problem does not appear. Only when making too many quick changes in the versatile thermostat device, the loop starts.
From my testing, it makes little difference if I change the preset, turn the binary heat/off switch on/off or change the temperature. After clicking a few times (like pressing “+” five times in a row to go from target temp 22,0° to 22.5° and then pressing “-” again for 3 times to go back to 21,0°) the loop begins, e.g.:
I think that whenever the TRV is still changing the valve position to switch to the new target temp, it will get stuck when you already change it to another target temp. But I have no explanation why this is only an issue when controlling it via VTherm. There is no problem when making exactly the same changes from the underlying Eve Thermo TRV device.
Neither the thermostatic valve nor the VTherm device are currently exported to Apple Homekit, so excluding them will most likely not help. As mentioned, here is my setup:
That’s all I did, and as soon as I tried to change the preset/temperature from the lovelace UI, the on/off loop started.
