Fun project. Though it’s kind of unreal how complicated it is to set up HA and I literally do this for a living, both embedded sw and backend web dev.Docker compose with a zwave management server, reverse proxies for TLS, vlan isolation for the server, macvlan for HA container so it does see the host network, etc, etc. All to turn on and off a lightbulb with the sun. All the while AI is telling me to configure things insecurely.
I think when I get some more spare time, I’d like to write a statically linked program that handles a zwave controller and basic automation scripting. No IP networking needed for my lightbulbs. Then it wouldn’t feel risky to just make a system user and udev rule to give it permissions to the controller, and run with systemd.

While you can run HA as a container. I think it's a mistake - Its more complicated and has reduced features.I would instead recommend people use HAOS instead - either running on dedicated hardware OR as a VM. Just dont run it from an SD card if you go down the Raspberry Pi/SBC route - it will kill the card from IO cycles.
I have an IOT VLAN on my network that all the IOT bits sit in, including WIFI devices. What internet access it gets (if any) depends on the device profile.
I tried splitting things up into multiple VLANs but a whole lot of things assume just a flat network, so things stop working if you get too fancy.

> it will kill the card from IO cycles.It might not. I have a Raspberry Pi 2 that has been running a weather station for over 12 years, and it has been on the original SD card. I have other RPi's doing dumb things around the house and I have never had an SD card failure.
YMMV and all that.

Yeah, I haven't had issues with SD cards in a long time. Many years ago (maybe 10), I think they weren't quite as good and I probably skimped too much when buying a card. RPi 1 also had power regulation issues. Now I only use higher tier cards and make sure there's enough free space for wear leveling and operations.by kalaksi
