A lot of smart devices are just an esp that basically does that. The zigbee and z-wave stuff isn’t even internet connected. A usb dongle connected to a PC running smart home software locally controls it.
It’s weird that so much has sprung up around personal homes when businesses had bacnet for years and years. Most of that stuff is wired up with basic analog inputs and outputs.
Personally, I like hardwired everything and would like to see more PoE stuff come out rather than wireless. I hate dealing with batteries because some people can’t deal with running low voltage wires.
It’s been a long while since I looked, but I remember it being a thing in tails to specifically not resize your browser window or only have it full screen to match a ton of other fingerprints.
Plus since it was a live distro that reset on every reboot it would only have the same fonts and other data as other people using tails. Honestly, I hate that all that info is even available to browsers and web sites at all.
