OpenHAB SMA Wechselrichter mittels Modbus einbinden
Hier findet ihr eine Beispiel Konfiguration für openHAB um via ModBus die Daten der SMA Wechselrichter eurer PV Anlage auszulesen. Ich kann so alle gewünschten Werte auslesen. Mittels einer Regeldatei ist noch der Gesamtstromverbrauch berechnet. Ebenfalls berechnet dieser die Einnahmen durch Einspeisung und auch die Ausgaben für den Zukauf vom Stromanbieter.
Ich habe die folgenden SMA Wechselrichter im Einsatz:
- SMA Sunny Tripower 8 (Solarpanels)
- SMA SunnyBoy Storage 3.7-10 (BYD Batteriespeicher)
Die Anleitung sollte aber auch sehr gut für andere Wechselrichter von SMA adaptierbar sein. Die aktuellen Modbus IDs bekommt ihr bei SMA zum herunterladen.
Alle unten stehenden Dateien findet ihr in diesem GitHub Repository
Aktivieren von Modbus auf den Wechselrichtern
Dies müsst ihr entweder durch eure PV Fachleute konfigurieren lassen, oder falls ihr die benötigten Installateur Rechte habt direkt über die Webkonfiguration der Wechselrichter.
Auf den Wechselrichter findet ihr die Einstellung unter Geräteparameter --> Externe Kommuniktion. Wenn ihr den Wert bearbeiten wollt, müsst ihr zuerst den Button Parameter bearbeiten anklicken:
Nach dem ihr das Ganze gespeichert habt, sollte der Wechselrichter via IP / DNS Name und Modbus TCP 502 erreichbar sein.
openHAB Vorbereitung
Um Modbus überhaupt in openHAB verwenden zu können, muss man als erstes das Modbus Binding installieren. Dies könnt ihr unter den Einstellungen --> Bindings machen. Hier einfach nach Modbus suchen und installieren:
Wir benötigen dann noch die Transformations Javascript und Map. Diese könnt ihr in den Einstellungen --> Transfomations suchen und installieren:
Nach dem nun alle Abhängigkeiten in openHAB installiert sind, können wir die Konfigurationsdateien anlegen.
Achtung bei openHAB 4 bitte auch prüfen ob die JavaScript Erweiterung installiert ist, wenn nicht einfach nachinstallierten:
Wechselrichter Things
Zunächst müssen wir für alle Items, Things anlegen. Diese werden zum Teil durch Transform Scripte erweitert, da sonst verfälschte Werte in openHAB ankommen.
Ihr müsst die IP Adressen in die euerer Wechselrichter ändern. Zu empfehlen ist auch, das die IPs der Wechselrichter fixiert sind nicht ändern können.

Transformation Scripts
Da die Wechselrichter zum Teil falsche Werte über Modbus liefern, müssen wir die Werte zum Teil umrechnen und bei Werten kleiner 0 entweder 0 setzen, oder gar einen undefinierten Zustand mit UNDEF.
conf/transform/smalimit1000.js
(function(i) {
if(i < 0) return "0";
return parseFloat(i) / 1000
})(input)
conf/transform/smalimit100.js
(function(i) {
if(i < 0) return "0";
return parseFloat(i) / 100
})(input)
conf/transform/smalimit10_undef.js
(function(i) {
if(i < 0) return "UNDEF";
return parseFloat(i) / 10
})(input)
conf/transform/smalimit.js
(function(i) {

Mapping Datei
Die Mapping Datei sorgt dafür das Zahlencodes in Lesbare Werte gewandelt werden. Zum Beispiel Statuscodes. Die Aktellen Werte für eure Wechselrichter findet ihr auch in der Modbus Dokumentation von eurem Wechselrichter.
