After less than 6 months already on my third unit. Both have had the WiFi transmitter fail on it. Luckily my ac contractor is a reputable outfit and is replacing them free of charge so far under their warranty and maintenance contract. Very unhappy.
Super easy to connect. Geo fencing is still a little buggy but it is a good thermostat. The vacation function is a little cumbersome if you need to make a change. You have to redo the settings but it works great once you program it right.
For some reason the contractor who installed the system didn't program the T6. Had to walk me through it over the phone twice, the first time, a reversing valve setting was wrong and the house got extremely hot until it changed. It's OK now.
The only thing that would make this product better would be if it could start the coffee and make toast in the mornings when I am home. I never have to worry about it, the temp goes up when we leave and comes on when we are coming home AUTOMATICALLY
