Now that Radio Thermostat has killed their support for their own app (who could have ever seen that coming /s) here's a dumb app to do basic control of the thermostat on your own.
Contained is a WPF app (that probably only works on Windows) and a Blazor web app with accompanying Dockerfile to make an image. I have this running on a Raspberry Pi 3B
All this is as-is. Treat it like the garbage code it is. Built with VS 2022.
