I have had the thermostat for a few weeks, and it is doing well. It has learned the house patterns, and it feels more comfortable. I live at the beach, and between 4 and 6 PM, the house is at its weakest cooling ability. The learning has helped it adjust, and we are very comfortable, instead of complaining. I did add sensors so that it averages the temp through the house. In my opinion, that is the golden ticket. I have added the door sensors and doorbell camera. Everything plays well with Apple.
