Since the Ecobee3 is home kit approved, should I go ahead and get it now, or wait? Are there any rumors that state Nest will become home kit approved in the next year or so? Also, should I go ahead and get the Ecobee3 now, or is there an update coming or are there better thermostats that are being worked on that are home kit approved? The only other one I could find is the Honewell Lyric, and it looks like the Ecobee 3 is better than that one. Thanks!
