I use an AMD mini-PC with Ryzen 5700u, 32GB RAM, connected with my home NAS. Similar software stack, the server is hosted via Proxmox, no issues.

I have a Zigbee antenna. Will have to double check. I’m pretty sure the lights work with the antenna, but scenes are only possible if you’ve integrated them (generally via hue through something like Homekit).

This is why it’s a great idea to refuse to install everything that’s possible, including smart switches, cameras, lights etc. that rely on the good will of some company to keep running.

Even then you can get fucked over. I’ve used Hue smart lights for years, and back when I bought them, you didn’t need an account to use them, just an app and network connection. Years later, they forced an online login for the app, requiring you to be online to interface with the bulbs. You can kind of work around it with Home Assistant, but you still need the account now to add the bulbs, and I don’t think scenes work without an account either now.

Rsync is great. I’ve been using it to back up my book library from my local Calibre collection to my NAS for years, it’s absurdly simple and convenient. Plus, -ruv lets me ignore unchanged files and backup recursively, and if I clean up locally and need that replicated, just need to add —delete.
