Product description

Style:DIY

 

From across the room or across the country, your Sensi Wi-Fi 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) for most installations, so it is compatible with the HVAC equipment in many homes* in U.S. & Canada. A c-wire is required for heat-only, cool-only and heat pump (without aux) systems, and for use with Apple HomeKit. Check to make sure it will work for you at sensicomfort.com/compatibility. The intuitive app walks you through each step of installation with custom configured instructions, removing all the frustration and guesswork from the installation process so you can be up and running in no time, no experience required.

Put your comfort on your terms using location-based temperature control with geofencing or creating custom heating and cooling schedules with the flexible 7-day scheduling option. Both energy saving features help to reduce your HVAC related energy costs so you can save money without compromising your comfort.

Sensi integrates directly with Amazon Alexa, Apple HomeKit, Google Assistant and Wink home automation platforms. Connect to Amazon Alexa to control your home temperature with simple voice commands, or just ask Siri to set, raise or lower your home temperature when using Sensi with Apple HomeKit.

Highly-rated for a reason

Named the ‘Best Value’ smart thermostat of 2017 by USA Today’s Reviewed. See for yourself why Sensi thermostat consistently receives outstanding reviews for its simple installation, intuitive app design and highly-rated customer support.

 
 

 

Works with the wires you already have.

The Sensi Wi-Fi Thermostat works with your home's existing wires and comes pre-programmed with hundreds of possible configurations, most of which do not require a common wire (c-wire).

So, when do you need a c-wire?

  • Heat Only and Cool Only systems
  • Heat pump systems without auxiliary
  • Using Sensi thermostat with Apple HomeKit

An easy, smart home upgrade you can do yourself.

Designed to be installed in as little as 15 minutes.

With the new Sensi mobile app, installation is even easier than before. Simply use the app to indicate the wires that are connected to your old thermostat, and it will automatically configure the setting that matches your home.

Even if you’re installing a thermostat for the first time, we have got your back. Clearly illustrated, in-app instructions will confidently guide you through installation from start to finish.

  • New mobile app with illustrated step-by-step instructions and video tutorials
  • Should you need any help along the way, our highly trained technical support team is available seven days a week.
 
 

 

Make sure the Sensi thermostat will work in your home.

Check compatibility using the free compatibility check tool on our website.

Sensi thermostat is not compatible with:

  • Line voltage or electric baseboard heating
  • Proprietary/ communicating/ serial protocol
  • Millivolt (mV) systems; but can be made compatible with the addition of a 24 volt transformer
  • Incompatible routers: Refer to Sensi's online compatibility resources.

Extensive compatibility with heating and cooling systems in most homes.

Compatibility is our top priority with Sensi Wi-Fi Thermostat. That’s why we designed it to work with the existing wiring on gas, oil, geothermal, heat pump and radiant heat systems – up to 4 stages of heating and 2 stages of cooling.

We think you'll agree, a Wi-Fi thermostat that does not require a common wire (c-wire) in most cases, and uses 2 standard AA batteries is a solution you can install with complete confidence.

The Sensi Wi-Fi Thermostat works with the following systems:

  • Conventional - up to two stages of heating and two stages of cooling (2H/2C)
  • Heat Only and Cool Only
  • Heat Pump (With or Without Aux) - up to 4 stages of heating and two stages of cooling (4H/2C)
  • Gas, Oil, Electric
  • Geothermal and Dual-fuel
  • This system type requires a common wire (c-wire). If you don't have a c-wire, 'Emerson Thermostat Common Wire Kit' is available for purchase
 

Control your home comfort your way.

We know your routine can change from day to day, and sometimes even minute to minute. That’s why Sensi thermostat gives you two different options to control your home comfort. With geofencing, Sensi uses your smartphone’s location to avoid wasteful heating and cooling when you’re away, and makes sure your home is exactly how you like it when you arrive. The 7-day flexible scheduling option lets you create and customize your home heating and cooling schedules to fit your lifestyle.

More comfort. More savings

With Sensi Wi-Fi Thermostat, you never have to choose between saving money and staying comfortable. Features including programmable heating and cooling schedules, remote access and location-based temperature control with geofencing help you save on HVAC-related energy costs without compromising your comfort.

In the know. No matter what

Even when you are not at home, your Sensi thermostat detects extreme temperatures and humidity levels and lets you know if your system isn’t working properly. In fact, the Sensi hardware is designed to control your heating and cooling, according to your settings, even if you lose your Wi-Fi connection. And with 1 degree accuracy, among the tightest tolerances marketed in the industry, your Sensi thermostat gives you the option of keeping your home temperature within one degree of where you set it.
