One of the key features of the Honeywell Lyric is its ability to use geofencing to set your thermostat to away mode. As a Nest owner, I love the idea, but was bummed when I watched the review over at CNET. They experienced all sorts of issues with the geofencing feature. It would set the thermostat to away even if a user was home. Not good, maybe a firmware or iOS update will fix it.
