Set Thermostat not working?

[Kulfsson]

I am wanting to move my RM legacy rules to RM 5.1, I know it is not required, but I just like to keep a clean setup. I currently have a Rule in legacy that I use to start heating my guesthouse when a Virtual Switch is turned on. It seems that in RM 5.1 I cannot choose the Thermostat Mode. Could this be a bug?

Your thermostat driver is likely out of date. Besides addressing that directly, there is a workaround you can do to properly set the values Rule Machine is looking for. See this post for that (or the whole thread for more details), substituting the modes your thermostat actually supports for the ones used in this case:

App fails since FW upgrade. Outdated Thermostat Driver

You have to temporarily change the driver for this thermostat to Virtual Thermostat (the pulldown for Type). After selecting Virtual Thermostat hit Save Device. Once you do that you need to put this into setSupportedThermostatModes command, and hit that button: ["off","heat"] Then put this into setSupportedThermostatFanModes command, and hit that button: ["off"] Then you will see the settings under Current State for supportedThermostatFanModes and supportedThermostatModes showing the words…

Oh yes! That worked. Thank you very much for sharing the workaround.
