I can't give it the full BIFL seal of approval, because it's only a few years old, but I have a Senville mini-split in the wall of the building I'm sitting in now. I got the Smart WiFi Kit for it and it has an app where I can manage schedules like you describe. It seems fine 3 years in.

Thank you!!

You are trying to do it the hard way. Just buy a plug in timer for the heater you have.

Oh my God I didn't think of that... 😑

FWIW, I just had a similar problem. I needed a bedroom at a higher temperature than the rest of the house because of a disabled relative, but it had to be a consistent temperature.

They have extension cords with built in thermostats but I like something more programmable.

I bought a Philips wiz wifi-controllable plug socket (I already use their bulbs) and I took my ecobee room sensor and put it in the room. Then I used smartthings so it turns on/off the heater based on temperature.

Anyway, not sure on your application but there are lots of options for this.

When you do this though, you have to buy a heater with physical controls. If digital, it won't automatically turn o just because the outlet has power.

Also heaters are dangerous and plugging the into an intermediary device isn’t sound. Neither is having one automatically go on if no one is home.

Ok Karen 👍

WTF? I speak from experience, I’ve put out way to many fires started by space heaters.
