Feature: ShineDiag — portabler Vor-Ort-Diagnose-Gateway (Pi 3B)

Flask-App + mobile Web UI für Diagnose vor Ort ohne HAOS/MQTT.
Pi 3B: eth0 → ShineLAN-X (DHCP), wlan0 → Hotspot "ShineDiag".
Browser auf http://10.0.1.1: Modell wählen, alle Sensoren auslesen,
Rohdaten-Register-Dump, Export als JSON.

-- [ ] Persistente History — Sensorwerte über Add-on-Neustart hinaus speichern
+- [x] Persistente History — SQLite in /data/history.db, 7 Tage Retention (v1.3.0)

+## ShineDiag — Portabler Vor-Ort-Diagnose-Gateway (Pi 3B)
+
+Hardware: Raspberry Pi 3B (eth0 → ShineLAN-X, wlan0 → WiFi-Hotspot „ShineDiag")
+
+### Pi-Netzwerk-Setup
+- [ ] eth0: statische IP 10.0.0.1/24, dnsmasq DHCP → ShineLAN-X bekommt 10.0.0.100
+- [ ] wlan0: hostapd Hotspot „ShineDiag", WPA2
+- [ ] Autostart ShineDiag beim Boot (systemd)
+
+### ShineDiag Web App (`tools/shinediag/`)
+- [ ] Flask-App: verbindet sich mit ShineLAN-X, liest alle Register
+- [ ] Mobile-freundliche UI: Modell wählen, alle Sensorwerte anzeigen
+- [ ] Rohdaten-Ansicht: Register-Adresse, Hex, Dezimal
+- [ ] Fault-Codes decodiert (Growatt Status-Register)
+- [ ] Export als JSON für Kundendokumentation
+- [ ] Pi-Setup-Script (install.sh)

+## Phase 4 — Messkonzept
+
+Ziel: korrekte, widerspruchsfreie Energiebilanz im HA Energie-Dashboard.
+
+### Messkonzept definieren
+- [ ] Messstellenplan: welcher Sensor misst was (SDM-630 = Netz, SPH = Batterie+AC, MIC = PV)
+- [ ] Hausverbrauch berechnen: `Hausverbrauch = PV_gesamt + Netzbezug - Einspeisung - Bat_Ladung + Bat_Entladung`
+- [ ] Vorzeichen-Konvention einheitlich festlegen (SDM-630 negativ = Einspeisung ✓)
+- [ ] Sensorüberschneidungen klären: SPH meldet AC-Leistung UND Netzleistung — was ist was?
+
+### HA Energie-Dashboard
+- [ ] Alle Dashboard-Slots mit den richtigen Aggregat-Sensoren belegen
+- [ ] Virtuelle Sensoren für berechnete Größen (Hausverbrauch) als MQTT-Sensor anlegen
+- [ ] Prüfen ob `total_increasing` auf allen Energie-Sensoren korrekt gesetzt ist
