One of the early entrants into the field on the HomeKit side is Honeywell, which has introduced
several different smart thermostats, starting with the second -
generation Lyric Round, which debuted early last year.I've been using a Lyric Round for quite a while now, and I've come to appreciate its integration with HomeKit and its ease of use, while Honeywell has continued to
improve its function and stability
over time.
