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.

My friend bought an ODROID and an SD card at the recommendation of some tech YouTuber for Home Assistant. Within 3 years the SD card was dead, and I had to help him re-set-up all of his stuff (this time, with a more resilient storage medium and remote backups).

YMMV certainly applies but I feel like the warning is important.

I wouldn't put running a weather station in the same class of disk activity as running Home Assistant. It is writing a fairly large amount of logs, plus statistics for every attribute/sensor for every device. The more devices you have, the more you will be writing.

There are regularly threads from people with "I restarted HA and now I get this weird boot error message", and it's because their SD card died.

You do you, but it's common enough of a problem that I think it's worth calling out as a "Don't do this".

I'm using OPNSense for the router, on their dedicated hardware - DEC750 iirc.

The switches are mostly Mikrotik, with some Unifi switches.

The wifi APs are all Unifi - they are all PoE and wired into the same network, no mesh. Even between buildings I ran fibre.

For the switching and routing, were I to do it again now I might go all Unifi. They recently implemented some much needed updates to make doing things like firewall rules and routing based on device much easier. I have a complicated set of rules in OPNsense to route IOT VLAN traffic out via a VPN connection, which require static IP assignments via DHCP, but under the new Unifi network I could do it with a few clicks and being able to use device attributes rather than a static IP.

I am also using an SLZB-MR1 for a ZigBee controller and Matter over Thread border router. I've got a bunch of IKEA and Mercator ZigBee light bulbs/fixtures that act as ZigBee routers. It's a strong enough mesh I rarely have issues with the ~180 devices on the net.

Interesting. I also run HA in a container and getting it to pick up my Zigbee dongle was so easy I don't even remember how I did it.

I haven't tried BT, but my HA box lives underneath a couch with a big steel pull-out bed so I don't imagine it would work very well anyway.

Add-ons (now apps) can't be done without HAOS. It's one of those non-obvious things.

There's other things I forget which are also more difficult/annoying to manage on the container version.

I have a rather large docker compose stack so my first experiments with HA were as running it there.

That lasted maybe a week before I went and ran it as a VM instead.
