I have the following setup and looking to add more “smarts” into it. These are really dumb no IR/remote anything.
z-wave power plug on each A/C unit (ZEN15)
rules setup that take readings from the room thermostat to set the temp control. Currently this is a hard rule in place if temp is greater than 73 turn on if temp is lower than 70 turn off. This is setup differently for different rooms. Some rooms are cooler than others and some hotter.
With the temp controls the AC units are all set on High (their built in thermostats don’t work anyways, never have when set to high). The AC units turn on/off based upon the temperature in the room.
If you have IR/remotes for your A/C units then you could probably set rules to keep them at a temp so if they are adjusted and turn on when they shouldn’t be then ST could adjust their temps back to be “correct”. I thought someone was working on a Sensibo smart app… and there’s another smart AC controller out there that could be interfaced with… can’t remember the name of it.
I have plans when I get around to it to make the thermostat work for the AC units to adjust the temp. So if the temp on the thermostat is set below current temperature then the AC units will turn on and vice versa. I can also add in other temp sensors as needed for areas where the temps vary a lot and average between them or pick the hottest one.
Note these thermostats are Heat only for the baseboard heaters. So going down in temp is ok as the heaters aren’t going to come on
