Alpine's pipewire-pulse package ships the daemon binary but doesn't auto-load the PA bridge module on alpine. We need to start pipewire-pulse as a separate process with -a tcp:4713 so PA clients (librespot, mopidy) can connect via TCP. Layout: - pipewire: audio server (native protocol) - pipewire-pulse: PA-compat bridge, listens on tcp:4713 + unix:/tmp/pulse-socket - wireplumber: session manager (loads BT modules, hot-plug handling)

Rebuild procedure from a fresh host
- Install Docker,
docker compose. - Clone this repo,
cd infra. mkdir -p mosquitto/data mosquitto/log(empty dirs for the volume mounts).docker compose up -d.- Pair zigbee devices (IEEE addresses in
zigbee2mqtt/configuration.yamlwill be wrong; re-pair or use the existingcoordinator_backup.jsonto rejoin the same network). just deployfrom the repo root to push the Node-RED flow.
Files that drift at runtime
nodered/flows.json— managed by the generator, do not hand-edit.nodered/node_modules/@flowfuse/node-red-dashboard/dist/index.html— patched bystart.shat every container start; survives reboots, lost ondocker compose down -v.mosquitto/data/— broker persistence, transient.zigbee2mqtt/database.db— sqlite, transient (regenerated fromconfiguration.yaml+coordinator_backup.json).zigbee2mqtt/state.json— committed so device ON/OFF state survives full rebuilds.
