Hi @Renzo
sorry, I made a little copy/paste mistake. I have to make a new PR and Jurgen a new test version to correct the max value for the scale.
And your thermostat doesn’t offer a mode, only temp_set.
You can see the difference between your device attributes and my example above with a mode.
Perhaps so can use a kind of mode in the Tuya app. The heater hase something similar. But that’s something which is not transferres via Tuya cloud service. It a kind of scene used in Tuya app, but that’s nothing we can use over the cloud API.
And what’s about Celsius? Homey is internally using °C and °F only for displaying. But perhaps that’s caused by the invalid boundary of 400° 
So please wait (again, sorry) for a new version. Yeah, that’s the disadvantage of a beta tester.
