Bought a house with @honeywell network-enabled thermostats. In order for me to control them, the previous owner has to unregister them. There isn’t a way from the device to unregister it. Seems like Honeywell missed a common use-case and made it far harder than it should be.

We had a Honeywell Lyric and it was a tremendous piece of garbage. Do yourself a favor and get a Nest, or even a “dumb” thermostat.
