I
t’s hard not to get excited about the pace of
“smart home” innovation. Things have advanced
enough to support actually useful smart lights,
vacuums, thermostats, cameras, washers,
dryers, and a ton of other devices. But that same
early energy means that companies enter and
exit the market constantly, leaving a lot of our
homes full of zombie gadgets. And even the
working ones all seem to require a new account
with a new password, maybe another hardware
gateway, and probably a recurring subscription
fee. Underneath a thin veneer of consistency
offered by Google or Alexa, things are pretty crazy.
Mostly that’s just part of the process. But it
bugs me when companies bait-and-switch,
adding recurring charges for functionality they
sold as a one-time purchase. That happened with
my Wink gateway last year, leaving me with a
house full of no-longer-smart lights. Annoying —
but fixing it gave me a good reason to dive into the
underlying tech and generate some fun code.
Z-What?
Most of the chaos around smart devices comes
down to the network — how do they connect to
the world? Increasingly this is just Wi-Fi, and
that’s probably where things will end up. But
