I’m surprised by how efficient this unit is. I’m considering purchasing a second unit for my sons room. My only complaint: you have to IMPROVE the app! I shouldn’t lose connection with the unit. I should be able to connect to the unit from anywhere. I have a Nest product that functions as so. It’d be nice to connect to my unit on my drive home from work.....And walk into a cool space!
