This air conditioner cools really well. Would recommend on that. 

The app appears that you must have it login to more than one device, (I used an older wifi tablet, that is occasionally used around the house) so that when you walk out of range you do not have to re-register the device every time. Also it should have more options than on and off times. A run timer function would be nice and a memory of where it was last set to, so that you don't have to reprogram it every time you turn it on. Also for your account when you set it up, it should bring up previously registered devices.

The item should be added to the list of Google Home items. This would probably fix everything I just mentioned.
