So I finally got an accepted offer on a house and I will be moving in about a month. I'm already starting to plan some upgrades and personal touches. Two things I am considering - a Nest (or other "smart" thermostat) and some type of "smart lock" for the front door. Does anyone here have any experiences with either the Nest (or a similar thermostat) or a smart lock (like the Kwikset by Kevo)? Suggestions/recommendations on either type of device? The house already has a security system in place, but I might be interested in upgrading that as well, so suggestions there would be appreciated as well.
