VThermo app

Yes, i use three sensors: Sensibo 0.1, Hue motion 0.01, Aeotec 0.1 Celsius reported

Any news if it will be possible to set the target temperature step with 0.1 C precision?
I see that the device capability you are using is similar to the thermostat device used in the Virtual Devices app and in the < groups > app.

Is this a capability that originates from Athom?
In that case I should probably ask them to update the thermostat device capability:
a. target temperature step with 0.1 C precision
b. ON option for thermostat mode (now it says only Automatic/Heat/Cool/Off). Without ON option, I cannot tell Google Assistent to turn on the thermostat, I am obliged to say “Set Thermostat to COOL” and that is a pain.

Please advise where I should go with my request?
