I never jumped on the “everything IoT” bandwagon, but recently I’ve relented a bit.

I own/use exactly 4 “IoT technologies”.

I have smart radiator thermostats that turn on/off the heat based on family presence, as well as “predict” the heating needs based on weather forecast, sunshine hours, etc.

I have a heat pump in my vacation house that is remote controlled by the internet. Not strictly needed, but very convenient in the winter.

To keep an eye on my vacation house I also have a camera that uses HomeKit Secure Video. Requires no infrastructure on my end except network.

And finally, like a lot of people I have Hue.

I control it all through HomeKit. I also keep everything on a couple of IoT VLANs, one for “trusted” devices (AirPlay, media, PlayStation, etc), and one for “everything else” with client isolation, filtered dns, IDS/IPS. No upnp/nat-pmp, no tunneling (if detectable), and no other dns servers but mine (until dns over https becomes a thing with IoT)

In the future however it might become more or less impossible to avoid. Our neighbors recently purchased a new oven, which of course comes with internet connectivity. Their new washing machine also has internet connectivity.

In the very near future everything will be connected under the pretense of providing useful feature, when in reality it’s all about pushing adds and gathering telemetry data.
