There is a driver for the below device. But one is needed for each indoor unit. I was going to buy one for my 6month old minisplit, but the steel holding my a-coil is rusted pretty deep. Don't want to give those guys more money for this thing to last 3 years. It's already expensive for what it is.
But there is a thermostat app and you can throw any temp sensor where you want it to measure off of.
