Geo-Fencing

Using the mobile app and Skyport, Venstar WiFi-connected thermostats know when you are leaving or coming home, maximizing comfort and energy savings.

Geo-fencing creates an adjustable perimeter around the home.

When the last person leaves the house and crosses the perimeter, the thermostat goes into energy-saving mode.

When the first person returns home, the thermostat goes into comfort settings.
