The solution i use on OpenWrt is basically-
Printer on airgapped IoT network
Computer on Internet network
Avahi allowed specifically for my printers MAC Address to access it from the Internet network.
Having smart stuff isn’t bad.
Having “smart” stuff that only works via a proprietary app over the internet is bad.
I like being able to dim several lights via a single command. I don’t like it being even possible from outside my house
Even worse, they sometimes kill their apps or remove functionalities.
It does take a lot of shopping to find the things that can work without a proprietary app though.
Yeah, Zigbee stuff is theoretically nice, but it’s an expensive setup that isn’t exactly easy for, say, my mom. And nothing is keeping Philips from going “haha, no, buy out proprietary stuff now”.
I’ve got Wiz on a standalone wifi, which works fine for me and it’s cheap, but it’s still a proprietary app (at least an open source project exists for it).
I haven’t implemented much but I’m planning on going with Shelly smart relays. I’m not a big fan of smart bulbs and stuff. I don’t know if that’s mostly what you mean by Wiz.
I was checking home assistant out and it seems to have quite a lot of things integrated so at least you aren’t a slave to their apps, even though it’s always connected to their servers.
Wouldn’t trust any IoT device that connects via Wifi.
Don’t forget the “S” in IoT stands for Security.
IoT devices focus on as many features as possible, for a as low as possible price. Security is always an after thought.
