Main features:
- Ranked "Highest in Customer Satisfaction with Smart Thermostat" by J.D. Power.
- Designed to work with existing wires, Sensi thermostat is universally compatible with most gas, oil, geothermal, heat pump and radiant heat systems. No other Wi-Fi thermostat works with more systems.
- Installs and works just like a standard thermostat until homeowners connect to Wi-Fi at their convenience.
- After connection, the free mobile app (compatible with Android and iOS) serves as an intuitive remote control so homeowners can set, change and schedule home temperatures from anywhere in the world.
- Custom 7 Day scheduling helps reduce wasteful heating and cooling to save up to 30% in HVAC energy costs.
- It is easy to add a company logo to the mobile app so your contact information is at your customers' fingertips.
- Works with Amazon Alexa for voice control (Alexa device sold separately) and Wink app (no Wink hub required).


From the couch, the car or the airport lounge, your Sensi thermostat makes it easy to remotely control and schedule your home comfort - Anytime. Anywhere.

Designed to work with the wires you already have, Sensi thermostat does not require a common wire (c-wire) in most cases, so it is compatible with most heating and cooling systems (U.S. and Canada only).

The intuitive app walks you through each step of installation and configuration so you don't even need to know what kind of system you have. You can be up and running in 15 minutes or less, no experience required.

Use your phone, tablet or desktop to adjust your home comfort or quickly create a 7-day schedule to reduce wasteful heating and cooling when no one is home.

But the most important feature is our customer satisfaction.
