Do I need a hard wire telephone line?

Does the unit work from a cell tower or does it need a land line coming into the home? We use 1Phone personal Hotspot as our internet connection therefore when we leave our home there is no internet connection from a router of any sort.

  • It does require a constant wifi connection to be remotely controllable from outside the home. To function as a regular thermostat and leverage the remote sensors though, the internet could be disconnected and not have a major issue. It really boils down to whether you need to be able to talk to the thermostat when you're away from home and your hotspot is not present.
