Do not buy this air conditioner if you plan to use with smart modes or expect support from LG. Read recent reviews of the app on the Apple App Store. Most are negative. I’ve had 2 of these air conditioners for about a month and received no support from LG. 
The SmartThinQ app is truly garbage. Called several times to resolve issues with programming smart modes for 2 window AC units and emailed at least 7 times and still nothing. When they did respond 2 of those emails, the responses had nothing to do with the problem. I purchased these units solely because of the feature to have home, away, pleasant, sleep and vacation modes configured for the units. None of these modes are configurable. Just notes “airconditioner alert”.

The app is also not compatible with IFTTT so if you want to set a mode to start if you enter a distance from your home, it is not possible.

If you are looking for a smart air conditioner, look elsewhere.
