I've read great reviews on the Ecobee3, and it seems the newest version with Apple HomeKit is the exact same except for it having Apple HomeKit. Should I go ahead and get the Ecobee3 now, or are there other smart thermostats coming out in the future? Since the Nest isn't going to use Apple HomeKit I can cross that one off the list. I read about the Honeywell Lyric, but that doesn't seem nearly as good as the Ecobee3.
