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.

I have an ecobee 3 that I've been using for about 7 years now. It works reasonably well. But I didn't like that eco+ or whatever they called it that they rolled out to everyone a while back.

Is there a thermostat logic add-on for HA that would replace the ecobee? I know I could program it with scripts and such but it'd be nice if there was some kind of "smart thermostat" module that could use the temperature sensors from around the house and learn the characteristics of the HVAC (how long does it take to heat/cool for a given outside temperature, for example, and take that into account when hitting a programmed set point) and maybe even integrate multiple sources of heating or cooling. (We have a pellet stove for supplemental heat that the HA could fire up, for example.)

That sets off my spidey sense.
