My fiance and I purchased the 12,000 btu window a/c unit with the wifi/app feature so we could remotely turn on and off or set the temperature where we want without being home. We were unaware that the feature also lets us know the room temperature as well. The unit works amazing and the app has been flawless. I have and will continue to recommend this product to everyone. I was at work when my fiance was home and I was playing with the unit thru the app to show a coworker. She text me and asked if I was messing with the A/C and my coworker bought one the same day!
