Failed to set thermostat...(not_ready)

[ks2018ks]

Describe the bug
Having re-enabled the app v2.0.7, after a period of not using it I now receive error "Failed to set thermostat...(not_ready)" for all thermostats.

Smartphone (please complete the following information):
Sony Xperia 5iv, Android 13

Additional context
Homey Pro 2023 10.3.0 rc12
HeatIt Thermostats & HeatIt App V3.6.2

Is this only during startup phase - which can happen due to dependencies. Or afterwards?

[ks2018ks]

It seems to be at the schedule change times

The error is definitly coming from Homey, or better the Heatit driver.

It could possibly be, that it's set to an automatic mode and such doesn't accept manual temperature changes?

Can you check the settings of the thermostat itself?

[ks2018ks]

Not sure what you mean by settings (i.e. which ones in particular?). If I select one of the devices in the Homey app I can manually change the temperature, or mode ("Comfort", "Energy Saving", etc.) or set it with a flow, without receiving an error message

Anything else I can do to try to work out what's going wrong?

I'm not sure what you meant by check "settings of the thermostat itself". What am I looking for that could throw up this error?

Hello,

I have the same problem.
Each time Homey restarts / rebooot, i have that kind of messages. (and i restart it quite often due to low stability...)

After a few minutes, the vthermo devices target temperatures do not follow the plans.
Generally, i restart heating scheduler 15 minutes after homey reboot and then it works.

Any help would be appreciated as my heating system is really not realiable with this problem.

Have a good day,
Paul
