New device request: Reliable Controls Mach-Pro

Hi guys, I gave this a shot myself following the docs to add a new OS but I’m out of my depth.

This is a building controller for an HVAC installation. I’m sure there’s more than can be done with it, but my only real desire is graphing temperature and humidity reading from the various sensors installed throughout the building.
