@xmiklos @dazzyp @oischinger I have the same issue.

If the status of "climate.vicare_heating" (ViCare Heating) is showing "Idle (Auto)" I get the error below if trying to setTemperature.

If the heating is on (i.e. Tado started the boiler heating) and the state of "climate.vicare_heating" (ViCare Heating)" shows "Heating (Auto)", then all commands work, including setTemperate.

Basically, I can only successfully issue setTemperate commands if the boiler is already actively heating. If it's Idle, not heating, then setTemperate commands fail from the Integration.

@stevensoave that's a limitation of the viessmann API. You can't set a target temperature if the heating is not activated.

I believe the argumentation is that it does not make sense to configure a temperature if you don't heat.

@woehrl01 Thanks. Half see their point. I can work with that now that I know, thanks. I'll just get HA to check that climate.vicare_heating" "(ViCare Heating)" shows "Heating (Auto), before setting a new temperature.
