To visualize the process, take a look at this install video of the Emerson Sensi thermostat. It won't be identical to the Ecobee3 Lite, but you'll get the general idea.
Integration and performance
Once the thermostat is installed and powered on, you can start adjusting the temperature, programming scheduled temperature changes and more. But, you should also download the Ecobee app on your Android or iOS device for remote access to your heating and cooling. That way, you can make adjustments and check the status of your thermostat anywhere your phone has a solid cellular or Wi-Fi connection.
But there are also a bunch of smart home partnerships to try out; I tested Alexa and HomeKit integrations to see how Alexa and Siri voice control worked with the Ecobee3 Lite. The $249 Ecobee3 is also Alexa- and HomeKit-enabled, so everything worked pretty much the same.
For Alexa, make sure you have an iOS 10., or , download the Alexa app and enable the Ecobee skill. Once that's set up, you can start asking Alexa to adjust the temperature for you. The same goes for Siri via HomeKit. To configure HomeKit, you can either follow the steps in the Ecobee app or use Apple's Home app, now available natively on iPhones thanks to
Everything I tested worked consistently well. The temperature changes kicked in promptly, the preprogrammed temperatures updated automatically and the automations I tested out were happily glitch-free.
Yea or nay?
Well, that depends. Ecobee's $169 Ecobee3 Lite Smart Thermostat is responsive, simple to program and seriously in tune with today's smart home market. If you already use or plan to start using Alexa, HomeKit, SmartThings, Wink or IFTTT, that's very good news. But if you aren't interested in asking Siri to change the temperature for you, a less expensive app-enabled model sans smart home partners will do the trick.
Are you intrigued by the Ecobee3 Lite, but not quite sold? Take a look at the $160or the $149 (due out this month). Neither one has as many integrations as Ecobee, but both work with select smart home partners and offer related apps.
