# EVCC Device Inventory — Schön Consulting Homelab
|
|
|
|
## Network Topology
|
|
|
|
EVCC runs as HAOS add-on on HA VM 106 (10.0.30.10), port 7070.
|
|
Config: `/mnt/data/supervisor/homeassistant/evcc.yaml`
|
|
|
|
## Configured Devices
|
|
|
|
### Grid Meter
|
|
| Field | Value |
|
|
|-------|-------|
|
|
| Name | `grid` |
|
|
| Type | `custom` (Modbus registers) |
|
|
| URI | `10.0.50.201:502` |
|
|
| Modbus ID | 3 |
|
|
| Power register | 30865 (input, int32nan) |
|
|
| Energy register | 30529 (input, uint32nan, scale 0.001) |
|
|
|
|
### PV Inverters
|
|
|
|
#### pv1 — SMA Inverter (main roof)
|
|
- Template: `sma-inverter-modbus`
|
|
- Host: `10.0.50.201:502`
|
|
- Typical output: ~700W daytime
|
|
|
|
#### pv2 — SMA Inverter (secondary)
|
|
- Template: `sma-inverter-modbus`
|
|
- Host: `10.0.50.203:502`
|
|
- Typical output: ~350W daytime
|
|
|
|
#### hoymiles — Micro-inverter (balcony)
|
|
- Template: `hoymiles-opendtu`
|
|
- Host: `10.0.40.55` (OpenDTU web interface, HTTP API)
|
|
- Typical output: ~670W daytime
|
|
|
|
### Batteries
|
|
|
|
#### battery — SMA Sunny Boy Storage
|
|
- Template: `sma-sbs-modbus`
|
|
- Host: `10.0.50.202:502`
|
|
- Max charge power: 4200W
|
|
- Watchdog: 60s
|
|
- Capacity: ~2 kWh usable (reported)
|
|
- Status: Working ✓ (SOC 99%, power 286W as of 2026-06-27)
|
|
|
|
#### marstek — Marstek Venus E (bridged via HA REST API)
|
|
- Type: `custom` (HA REST API bridge — NOT template, NOT Modbus)
|
|
- Physical device: 10.0.50.113 (Modbus port 502 closed from EVCC network)
|
|
- HA integration: Working ✓ (reads via HA Modbus integration, all entities available)
|
|
- Bridged via HA entities:
|
|
- power ← `sensor.marstek_venus_modbus_ac_leistung`
|
|
- soc ← `sensor.marstek_venus_modbus_batterie_ladezustand`
|
|
- energy ← `sensor.marstek_venus_modbus_gesamte_entladeenergie`
|
|
- Capacity: 5 kWh, maxchargepower: 2500W, maxdischargepower: 2500W
|
|
- Status: Working ✓ via HA bridge (verified 2026-06-27: power=0W, soc=100%, energy=336.34kWh)
|
|
- Controllable: No (read-only). For control, add `limitsoc`/`batterymode` setters targeting HA entities.
|
|
|
|
### Charger
|
|
|
|
#### wallbox — SMA EV Charger (bridged via HA)
|
|
- Type: `custom` (HA REST API bridge)
|
|
- Physical device: 10.0.50.205 (CN=SMA3010510346.local)
|
|
- HA reaches it via 192.168.100.95 (different VLAN)
|
|
- Direct EVCC connection fails: TLS cert without IP-SANs + SMA API returns 400
|
|
- Status: Working ✓ via HA bridge
|
|
|
|
### Tariff
|
|
- Provider: Tibber
|
|
- Token stored in EVCC config (not in 1Password — rotate if needed)
|
|

## Diagnostic Commands
|
|
|
|
```bash
|
|
# Full EVCC state
|
|
curl -s http://10.0.30.10:7070/api/state | python3 -m json.tool
|
|
|
|
# Quick health check — extract key metrics
|
|
curl -s http://10.0.30.10:7070/api/state | python3 -c "
|
|
import json, sys
|
|
d = json.load(sys.stdin)
|
|
print(f'Grid: {d[\"grid\"][\"power\"]}W')
|
|
for i, pv in enumerate(d.get('pv', [])):
|
|
print(f'PV[{i}] ({pv[\"name\"]}): {pv[\"power\"]}W')
|
|
bat = d.get('battery', {})
|
|

|
## EVCC Config File Locations on HAOS
|
|
|
|
```bash
|
|
# Find all copies
|
|
qm guest exec 106 -- find /mnt/data -name "evcc.yaml" -maxdepth 5
|
|
|
|
# Results:
|
|
# /mnt/data/supervisor/tmp/tmpXXXXXX/data/evcc.yaml — temp, ignore
|
|
# /mnt/data/supervisor/homeassistant/evcc.yaml — MAIN (referenced by config)
|
|
# /mnt/data/supervisor/app_configs/<hash>_evcc/evcc.yaml — addon-managed copy
|
|
```
