Yeah, not this thermostat.

Bloody proprietary shit that, fortunately, another fella managed to write a reasonably well-featured HA add-on for. But it still goes via their cloud service, and the problem is it uses a proprietary protocol over 2 or 3 pair wire,. Additionally the evaporative A/C plugs directly into the heater unit, which handles C&C for both appliances.

I haven't ruled out having to separate the buggers out and control each individually. As long as I can find a thermostat that can handle them.
