Zen Thermostat

The Zen Thermostat is a ZigBee device that works with SmartThings to monitor and control your home's climate. Keeping your home in the perfect temperature range has never been easier! Once combined with Routines and phrases, the thermostat can automatically adjust set-points to suit your needs and comfort.

Zen keeps you cool on scorching summer days, makes your home warm and cozy during snowy winters, and looks dang fine all the while. But before you can reach this state of Nirvana, you have to set up the Zen Thermostat.

Note: The Zen Thermostat is compatible with the SmartThings Classic app.
