• Three PiHole instances, synced with Orbital Sync
• Unifi Controller

And some small services to pipe metrics into Grafana dashboards for apps that don't have native support for metrics. Most of this is managed through Docker with a Traefik reverse proxy with letsencrypt certs for https.

My most useful so far has to be openhab. I'm barely using it to it's full potential but it's so freeing to be able to buy (nearly) any smart device and know I can integrate it with the rest of my system. It also allows me to block Internet access to most of my smart devices completely for added privacy.

Second most useful is probably the Jellyfin/*arr stack to manage and view my collection. Soon I'm planning on adding either Calibre or something similar for books to sort my ebooks and old digital textbooks.

And once you have two or three services, monitoring obviously helps. I honestly wish I had set it up earlier, in particular Uptime Kuma for general uptime tracking. It would have saved me so much time pinging all my services to try to diagnose issues.
