Restart Strix Halo Power Monitor

Use this skill when the Strix Halo Power Monitor web app or its Tailscale endpoint is unhealthy, non-responsive, or when the user explicitly requests /restart-power-monitor or "重啟 power-monitor / 電源監控 / 電費監控服務".

Just run it

Run the automated restart and diagnostic script on the host:

bash ~/.hermes/restart-power-monitor/scripts/restart.sh

The script automatically performs the following actions:

1. Rebuilds and restarts the power-monitor container (FastAPI + WebSocket backend).
2. Force-recreates the tailscale container (sharing network namespace with the backend).
3. Verifies local API responsiveness at http://localhost:8085/api/stats with a 30-second retry window.
4. Validates the Tailscale node status and resolves transient offline states (auto-restarting container if network is reported down).
5. Tests the public HTTPS endpoint https://power.crayfish-monitor.ts.net/ to verify SSL reverse-proxying and Funnel reachability.

Live Architecture

Piece	What	Managed by	Location
Backend & UI	FastAPI + SQLite database + HTML templates	Docker Compose service power-monitor (Port 8085:8000)	main.py
Tailscale Sidecar	Tailscale node providing SSL HTTPS + Funnel on power.crayfish-monitor.ts.net	Docker Compose service tailscale (network_mode: service:power-monitor)	ts-entrypoint.sh

[!IMPORTANT] Because the tailscale sidecar uses network_mode: service:power-monitor, any recreation of the power-monitor container invalidates the old network namespace. You MUST recreate/restart the tailscale container as well. Do not restart them individually via simple docker restart.

Manual Troubleshooting

If the script fails, follow these steps to manually diagnose the service:

A. Inspect Logs

# Check FastAPI backend logs
docker compose -f ~/src/power-monitor/docker-compose.yml logs power-monitor

# Check Tailscale sidecar and proxy logs
docker compose -f ~/src/power-monitor/docker-compose.yml logs tailscale

B. Verify Tailscale Status inside Container

If the public FQDN doesn't resolve, check if the Tailscale daemon inside the container is authenticated:

docker exec power-monitor-ts tailscale --socket=/tmp/tailscaled.sock status

If it shows "Tailscale cannot connect because the network is down", run:

docker compose -f ~/src/power-monitor/docker-compose.yml restart tailscale

C. Manual Deploy

If Compose configuration changes:

cd ~/src/power-monitor
docker compose up -d --build power-monitor
docker compose up -d --force-recreate tailscale
