Very much getting into the whole homelab thing.
I’ve got four Raspberry Pis swarmed up and running a blog, a password manager, book stack and Prometheus. I’ve then got a couple of NUCs (older 5th-gen i5) with proxmox running Plex and Home Assistant. The HA is running Grafana pulling in data from the Prometheus instance in the swarm. A single, very old Pi 2 running Wireguard, Cloudflare tunnels and Nginx Proxy Manager.
And it’s all snappy and running around 30°.
Happy to share notes!
