This essentially means the Lyric can be controlled using the SmartThings Hub and its companion app. You can configure Routines or use SmartApps (downloadable app extensions) to automate all kinds of tasks involving the smart thermostat. For example, there’s a SmartApp called the Thermostat Mode Director that can automatically turn off your thermostat if any windows/doors are open (requires compatible window/door sensors, of course).
Pairing the hub and the thermostat is pretty straightforward: Open the SmartThings app on your iOS or Android device, navigate to Marketplace > Things > Climate Control > Thermostats > Honeywell, select “Honeywell Lyric Thermostat”, tap Connect Now and enter your Honeywell credentials. That’s it, you’re all set up.
Why this matters: The Lyric is seen as Honeywell’s answer to the category-defining Nest Learning Thermostat. But until now, it was far behind the latter in terms of third-party integrations, the one thing that matters most when choosing between smart-home devices. The company has plugged that gap to some extent by integrating Lyric with SmartThings and HomeKit.
