With built-in Amazon Alexa Voice Service, the ecobee4 can listen to your voice commands and respond. Have it set a timer, read you the news, adjust the temperature, and more, even from a distance thanks to far-field voice recognition. It also works well with other Alexa Devices by supporting ESP so that only the device closest to you responds to your commands. In addition, ecobee4 comes with a room sensor that helps manage hot or cold spots in your home to deliver the preferred temperature to the rooms that matter most. Ensuring comfort when you’re home and savings when you’re not, ecobee4 pairs with up to 32 sensors and works with Amazon Alexa, Google Assistant, Apple HomeKit, Samsung SmartThings, Wink, and IFTTT. Even better, it comes backed by a 3-year limited warranty for peace of mind.
