I've pared things down quite a bit lately; the setup here used to be:
- A Mac Mini, a Pi 4 with SSD and 8GB RAM and a Pi 3B+ forming a "multi-room" Kubernetes cluster with the idea that sensors and automation for each room (that had one) could be run locally in that room, including wired sensors, all connected by Kafka running on one of the Pis; that way I could just plug in another sensor and the local pod would know what to do with it. I never found a reliable way to allow pods to use serial devices and such, so while it's been fun, shifting priorities mean I had to scale it down to just the Pi 4 running HASS, Zigbee2MQTT, Mosquitto, NodeRed, uStreamer and a simple homebrew TTS API based on espeak. It's all docker-compose now, since docker works a lot more reliable with devices. It's a real shame, kustomize/flux/k8s is so much nicer for robustness and easy configuring (a second, different instance of my stack is running elsewhere, so I need that) and monitoring, debugging, ... is way more convenient, but I need those sensors to work and I can't spend as much time fiddling with it as I previously did, so it's docker-compose and Ansible for now.
- A Pi 3 running OctoPrint; since made redundant as my 3D printer (Prusa Mini) got the ability print over LAN with the last update. The webcam I use to monitor it is now running via uStreamer on the Pi 4. It's going to become the brains for the Freenove Big Hexapod Robot kit I've been gifted last Christmas.
- A Pi Zero W running a large-ish e-ink display with weather data and things like that. Still around, terribly useful, I'd love to have a second (but possibly one that doesn't take seconds to refresh...)
- A Synology running a Prometheus/Grafana stack, a MySQL, a docker registry for the Kubernetes cluster, Gitea with all the manifests and flux config so I could rebuild the Kubernetes cluster without internet access. Also still around, but I'll get rid of some of the stuff running on there. Reducing its attack surface and such.
And I'm using Tailscale like everyone else these days.
Waveshare epd7in5_V2 and no case, there's a smallish wood block on the left and right lower corners with a shallow cutout that the display slides into, so it's kinda wedged between the wood blocks. Looks kind of like a post card given its thinness.
