ioBroker Tutorial-Reihe - Alfen-Wallbox per Modbus integrieren
Nachdem wir nun elektrisch fahren, musste natürlich auch eine integrierbare Lade-Lösung her. Nach etwas Recherche habe ich mich für die Alfen Single Pro-Line entschieden. Diese kann nicht nur per Software-Upgrade auf 22kW gebracht werden (was in ein paar Jahren ja interessant sein könnte), sondern hat auch viele Schnittstellen. Unter anderem kann man die Wallbox per Modbus in ein beliebiges anderes System aufnehmen. Wie genau das klappt, welche Register es gibt und wie man diese auslesen / schreiben kann, zeige ich Dir alles in diesem Beitrag.

Register
Die folgenden Register stehen unter Slave-Address 200 zur Verfügung:

Da nicht alle Register interessant sind, hier eine gefilterte Liste mit relevanten Informationen:
| Beschreibung | Start | Ende | Länge | Datentyp |
|---|---|---|---|---|
| Name | 100 | 116 | 17 | STRING |

| Charge phases | 1215 | 1215 | 1 | UNSIGNED16 |
Davon sind allerdings auch längst nicht alle Infos spannend. Ich würde nur die folgenden Register anlegen:
| Beschreibung | Start | Ende | Länge | Datentyp |
|---|---|---|---|---|
| Voltage Phase V(L1-N) | 306 | 307 | 2 | FLOAT32 |
| Voltage Phase V(L2-N) | 308 | 309 | 2 | FLOAT32 |

| Current Phase L1 | 320 | 321 | 2 | FLOAT32 |
| Current Phase L2 | 322 | 323 | 2 | FLOAT32 |
| Current Phase L3 | 324 | 325 | 2 | FLOAT32 |
| Frequency | 336 | 337 | 2 | FLOAT32 |
| Real Power Sum | 344 | 345 | 2 | FLOAT32 |
| Real Energy Delivered Sum | 374 | 377 | 4 | FLOAT64 |
| Active Max Current | 1206 | 1207 | 2 | FLOAT32 |
| Max Current valid time | 1208 | 1209 | 2 | UNSIGNED32 |
| Max Current | 1210 | 1211 | 2 | FLOAT32 |
| Safe Current | 1212 | 1213 | 2 | FLOAT32 |
| Charge phases | 1215 | 1215 | 1 | UNSIGNED16 |
Besonders spannend ist das Register 1215, welches die Umschaltung zwischen 1- und 3-phasigem laden erlaubt. Dort kann man eine 1 oder eine 3 schreiben. Dazu aber wann anders etwas mehr.
