Reddit mentions of Remotec Z-Wave ZXT-120 IR Extender for Air Conditioners

If your AC has a remote control you can use a z wave IR device to manage the AC. Look up:

There are other devices with similar capability as well.

Check out this guy. I use 8 of them in my barndominium to control the head units of my mini-split system in each room. Works great. Takes a little time to figure out how to program them for your specific units but once it's up and running, everything works well.

> Nah, I have split system 220V. I need to research more.

A few ideas

• temp sensor, if room is normally hot but gets cool AC must be on
  
  
• tilt sensor, I wonder if you could put a tilt sensor on the louver of the split system. Not sure if they are strong enough to push the weight of the sensors. They are made for garage door.
  
  
• door strip sensors, they are ultra thin and could work. Again on the louvers so you can tell if they are Open and running or closed and not running https://www.thesmartesthouse.com/collections/door-window-sensors/products/sensative-z-wave-plus-strips-invisible-door-window-sensor
  
  EDIT: I forgot to mention then you can use a ZXT-120 to control the split system. I use them on my Mitsubishi split and they work fine. I have 6 of them. https://www.amazon.com/Remotec-Z-Wave-ZXT-120-Extender-Conditioners/dp/B00Q6SXTPS/ref=sr_1_1?ie=UTF8&qid=1501630141&sr=8-1&keywords=zxt-120

I use one of these zwave IR blasters designed for a/c units.

A/C units typically get sent multiple codes at once. Very few learning remotes seem to be able to work. I use this with my Split Duct unit and it works reasonably well.

IR control is the way to go.

Many of these more advanced HVAC systems use proprietary controls, so it won't work with any thermostat from another brand.

You can get any window unit that is controlled by an IR remote to work with Wink using the Remotec ZXT-120 z-wave/IR gateway. You will need a secondary controller to configure the ZXT-120 to control your specific brand of window AC, but after that, it presents to Wink as a thermostat.

One of the reviews on Amazon describes how to get it working Wink, and I can confirm that those instructions work.
