# ha-diag-agent — deployment i testy

## First-time deployment

See **[DEPLOY.md](DEPLOY.md)** for the full procedure: HA token creation,
per-host `.env` config, deploy commands, verification steps, 48h shadow-mode
observation, and rollback.

**Shadow mode** (`HA_DIAG_SHADOW_MODE`, default `true` on the control-plane):
`ha_websocket_dead` events are downgraded to `alert_only` with a `[SHADOW MODE]`
note instead of queuing an automatic `container_restart`. Set to `false` in
`/opt/homelab/config/control-plane/.env` on the VPS when ready for live actions.

## Deployment

```bash
# 1. Create config on target node
ssh oskar@<node-ip>
mkdir -p /opt/homelab/config/ha-diag-agent /var/lib/ha-diag-agent
cat > /opt/homelab/config/ha-diag-agent/.env << 'EOF'
HA_URL=http://homeassistant.local:8123   # or http://100.70.180.90:8123 for chelsty-infra
HA_TOKEN=<long-lived-token>
NODE_NAME=piha                           # or chelsty-infra
LOCATION_TAG=ken                         # or chelsty
CHECK_INTERVAL=60
EOF

# 2. Deploy
scripts/deploy/deploy.sh --service ha-diag-agent

# 3. Verify
docker ps --filter name=ha-diag-agent
docker exec ha-diag-agent python -c "import urllib.request; print(urllib.request.urlopen('http://localhost:8087/health', timeout=5).read().decode())"
```

### chelsty-infra note

`chelsty-infra` runs docker-compose v1 (1.29.2). Use `docker-compose` (hyphenated):
```bash
docker-compose -f docker-compose.yml up -d --build
```

### HA long-lived token

In HA UI: Profile → Long-Lived Access Tokens → Create token.

## Running Tests

```bash
cd services/ha-diag-agent
pip install -e ".[dev]"
pytest tests/ -v
```
