Smartphone remote.

Because carrying the thermostat around is just silly.

When you install an Insteon Thermostat in your home and link it to the Insteon Hub, every smartphone and tablet you own becomes a remote control. It doesn't matter if you're hiding under the covers on a cold winter morning or running late out of the office on a sweltering summer evening, you can adjust the temperature from anywhere and ensure that your home is comfortable all the time.


Winter Weather Watch

Keep the blizzard outside and ensure your home is toasty warm by turning up the heat remotely.


Summer Sun

Cool down the house when you're on your way home on a blistering summer afternoon.


Bon Voyage

Turn off the AC even after you've left. Especially helpful for impromptu expeditions.


Control on Apple Watch

With the Insteon App on Apple Watch, you don't even need to reach for your iPhone to adjust the Thermostat. Change your Thermostat mode right on your wrist.
