I am very pleased with the T-6 it has operated by far the best and simple to install love the Wi-Fi connect and the capability of Geofencing. I am recommending this t-stat to everyone.
Mostly good however lost wi-fi connection within a few hours of setting up. Had to google to see how to reset connection as there is now way to do this from the t-stat menu. The suggested pull off the wall and put back did work, but not a great 'fix'
