I've had other digital thermostats but they did not cooperate with our slower internet service. We had repeated issues with the device. This connects through its own Wi-Fi, and does not monopolize our bandwidth in any way. It is efficient, easy to set up in your home and to connect to the app. The app is easy to use and understand. Overall I would like the far above its competitors, it's simplicity is it's wonder, and it's glory.
Dropped off Wi-Fi and I had extreme difficulty getting back on WiFi system. I kept getting an error message and could not process to complete. It took over half dozen tries to get a successful completion.
