Zernet Door Window Sensor

Stops global cooling.

Zernet is the only aircon controller smart enough not to cool the outdoors. Think how much money you’ll save!

Smart door sensor

With the optional smart door sensor installed, you can:

  • Specify exactly what your AC should do to save energy when one is left open.
  • Power down the AC if doors are open longer than 30 seconds (or any amount of time).
  • Alert you through your smartphone.

It’s a smart window sensor, too

The same smart sensor device works with any windows you want monitored.
So next time a door or window is left open, let Zernet handle it and save energy.
