Sensi Smart Thermostat, Wi-Fi, Energy Star Certified, Alexa, 1F87U-42WF

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 sensi.emerson.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 with the ENERGY STAR certified Sensi thermostat. Both energy saving features you save about 23% on your HVAC energy usage* so you can save money without compromising your comfort.
Plus, 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. What’s more, Sensi Wi-Fi Thermostat has been named the ‘Best Value’ smart thermostat of 2018 by USA Today’s Reviewed.com
