A lot of that stuff is homebrewed with open source software, at least among the programmers I know. My coworkers who are all in on the latest Nest or Alexa crap tend to be young executive/management types who are overly concerned with "lifestyle". The kind of guys who dress like they're heading to the yacht club straight after work.
