0cd481a5ea Add Docker Compose stack for son's installation (evcc + Prometheus + Grafana)
Self-contained stack for DS218 Synology targeting:
- 2x Fronius inverters (11+22 kW) via shared DataManager, Solar.API v1
- BYD 12 kWh battery connected through Fronius
- 2x Elli Charger Connect 2 via OCPP 1.6j
- evcc handles PV surplus charging, OCPP server built-in
- Prometheus scrapes evcc /metrics, 90d retention
- Grafana auto-provisioned with evcc dashboard and Prometheus datasource

Setup: edit .env (3 IPs + 2 station IDs), point Elli app to OCPP backend,
docker compose up -d. README in German for non-IT handover.

ca0f9ed1c3 house/son: placeholder config for son's installation
All house-specific values (IPs, coordinates, Viessmann credentials, kWp)
replaced with <...> placeholders. Ready to fill in once hardware is known.
Notable differences from house/lutz template:
- installation_id left empty (disables WW boost until credentials obtained)
- base_load_w set to 400W (adjust after measuring)
- forecast lat/lon/declination/azimuth/kwp all require local values

# EMS Stack — Einrichtung auf der Synology
## Was läuft hier?
| Dienst | Adresse | Funktion |
|---|---|---|
| evcc | `http://SYNOLOGY-IP:7070` | Ladesteuerung, PV-Überschuss, Haupt-UI |
| Grafana | `http://SYNOLOGY-IP:3000` | Historische Auswertungen |
| Prometheus | `http://SYNOLOGY-IP:9090` | Metrik-Speicher (intern) |
**Passwort Grafana:** `ems2024` (Benutzer: `admin`)
---
## Einmalige Einrichtung
### 1. Synology vorbereiten
Im Synology **Package Center**: **Container Manager** installieren (kostenlos).
### 2. Dateien auf die Synology kopieren
Den gesamten Ordner `deploy/son/` per FileStation oder SCP auf die Synology kopieren,
z.B. nach `/volume1/docker/ems/`.
### 3. `.env` anpassen
Die Datei `.env` im Texteditor öffnen und ausfüllen:
```
SYNOLOGY_IP=192.168.1.100 ← IP-Adresse der Synology
FRONIUS_IP=192.168.1.XXX ← IP-Adresse des Fronius DataManagers
ELLI_A_STATION_ID=ELLI-... ← Station-ID aus der Elli-App (Wallbox A)
ELLI_B_STATION_ID=ELLI-... ← Station-ID aus der Elli-App (Wallbox B)
```
**Station-ID in der Elli-App:** Einstellungen → Ladestation → Station-ID
### 4. Elli Wallboxes konfigurieren
In der **Elli-App** für jede Wallbox:
- Einstellungen → Backend / OCPP
- Backend-URL: `ws://SYNOLOGY-IP:8887/ocpp`
- Station-ID: wie in `.env` eingetragen
### 5. Stack starten
Im Synology **Container Manager** → **Projekt** → **Erstellen**:
- Projektname: `ems`
- Pfad: Ordner mit der `docker-compose.yaml`
- Starten
Oder per SSH:
```bash
cd /volume1/docker/ems
docker compose up -d
```
### 6. Prüfen ob alles läuft
- evcc öffnen: `http://SYNOLOGY-IP:7070`
- Unter **Geräte** sollten Fronius (PV + Batterie + Netz) und beide Wallboxen grün erscheinen
- Grafana: `http://SYNOLOGY-IP:3000` → Dashboard **evcc — Laden & PV**
---
## Wenn ein Fronius-Wechselrichter eine eigene IP hat
Falls doch zwei getrennte DataManager (zwei IP-Adressen):
In `evcc.yaml` den Abschnitt `meters` → `pv` auf zwei Einträge aufteilen:
```yaml
- name: pv1
type: template
template: fronius-solarapi-v1
host: 192.168.1.XXX # Wechselrichter 1 (11 kW)
usage: pv
- name: pv2
type: template
template: fronius-solarapi-v1
host: 192.168.1.YYY # Wechselrichter 2 (22 kW)
usage: pv
```
Und in `site.meters.pv` beide eintragen:
```yaml
pv:
- pv1
- pv2
```
---
## Updates
```bash
cd /volume1/docker/ems
docker compose pull
docker compose up -d
```
