Smart home integration

What is the Honeywell Home geofencing feature?

The geofencing feature is location-based scheduling which can intelligently override the time-based schedule of your thermostat. If your schedule varies or you regularly depart and return at different times, the Lyric Thermostat can automatically adjust to your life. Geofencing brings you comfort when you’re home and savings when you’re away.

When you enable the Lyric geofence schedule, it intelligently overrides your

fixed program schedule based on whether you are home or away.

• Active geofence schedule is indicated by the "geofence" logo in the top left corner of the screen. Home/Away status is indicated by the "house" logo and "away" logo.

• To learn more about configuring the geofence schedule, see the geofence menu in your Honeywell Home app.

• Geofencing can only be configured using your Honeywell Home app.

• To learn more about how smart geofencing can work for you and how it fits to your busy lifestyle, go to getconnected.honeywell.com

How do I set up geofencing with my Honeywell Home product?

For setting up Geofencing you need to be in the same location as your Lyric thermostat and have the location services (preferably including GPRS) of your phone switched on.

During the registration of your Lyric thermostat within the Honeywell Home app, you will have the option to also configure Geofencing. Please follow the on-screen prompts.

How does Geofencing work with mutiple people using the Honeywell Home App?

In case of multiple users the last user who is exiting / leaving the Geofencing boundry set up around your home is triggering the Geofencing AWAY setting, while the first user returning is triggering the Geofencing HOME setting.
