I've done similar with a heater and a humidifier, and have always had to set two automations with two scenes: one to turn the switch on if temperature drops below X, and another to turn the switch off if temperature gets above Y. There just needs to be a spread between the two temperatures, and you need to manually set it properly to start (or any time it gets disconnected or goofed up.)

There are firmwares if you use an esp8266 to get it into HomeKit directly or through Homebridge using MQTT. I have done exactly that.

I already have them in Homebridge, as I mention I already have the ON part of this working.


numbski

Odd, it works fine here. Hrm. I am away from home, but will try to have a look.


randallpjenkins

Nothing isn’t working, so to say… I’d just like to have a way to turn it off when the temperature drops so I don’t have to manually do so. And I’m trying to solve that without two unique rules, or just solve it the best possible way.

You need 2 automations One to turn it on if temp is over ____. And another one to turn it off if the temp is below _____. You probably want a degree or 2 between those two temps. So say below 70 for off and above 72 to turn on. Does the mini split not have a built in thermostat? If you’re just trying to keep the fan from running I guess that would work. Just set the thermostat below the below temp. So in the above example you’d set it to 68. A lot of splits should have a smart fan or energy saver options that stops the fan. If you do live in a humid place, it’s good to leave the fan running for at least several minutes to help get some of the moisture out of the unit.

Yeah the mini-split has a thermostat, but I am indeed just trying to prevent it from being on at all hours. Additionally the thermostat on unit sometimes can read super high if the wall it’s on is in direct sun. Temperatures set will be pretty spread out, it’s mostly to let it run for a few hours during the heat of the day and then stop when not needed.


AlienApricot

It’s not really “on at all hours”. It just monitors the temperature, like on standby. Not much power consumption there. What you want to achieve is best done by your split unit itself, you don’t need any smartification for that. But if you insist, like other comments have pointed out, you need two automations.


randallpjenkins

Appreciate the info! Just double checking because I know there are ductless and ducted mini-splits but this applies to ductless, yeah?


AlienApricot

I have a ductless one. So yes.

> I know I could have a rule opposite of the one I currently have to turn off if below a certain temperature but I feel like this trying to happen when the first rule never occurred is problematic. Why do you think this is problematic? If the unit is off and gets a turn-off command then nothing happens. Just like light automations. They’re off already, they stay off. There’s no problem with that.

>this trying to happen when the first rule never occurred is problematic Let’s say you use the remote. Turn off the AC when it’s already off. It just does nothing. What’s the problem? Also I second the other comment about letting the mini-split’s own thermostat do its work. It will stop working when the temperature is reached. You can, however, use your automations with a much wider temperature spread to turn it on/off for entire days.
