Hallo, ich habe den verkabelten Pekaway Shunt gegen einen Victron Energy SmartShunt IP65 300A/50mV - Smart Shunt Batteriewächter (Bluetooth) getauscht.
Dieser soll via BT verbunden werden:
Leider werden bei der Shunt Anzeige aber nur “wirre” Daten angezeigt:
Geht das so oder soll ich ihn via BT BLE anbinden: Victron Geräte Verbindung via Bluetooth - Stromversorgung - Pekaway
machs über Victron BLE und ich schick dir meinen flow dazu

Hallo Mario, vielen Dank für deinen Flow.
Leider bekomme ich keine Werte geliefert. Beim Blue Smart IP22 Charger kommen Werte.
hast du die Mac Adresse und den kodierschlüssel ersetzt?
Ja hatte ich.
Ich musste aber die scanner.py anpassen Victron Geräte Verbindung via Bluetooth - #44 by Vincent
Nur Batterie 1 werden keine Werte angezeigt. Batterie 2 auch nicht, aber die habe ich auch nicht angeschlossen. Ebenso kommt die MAC und TTGO nicht, wobei TTGO noch einen Tag dauern kann:
ah batterie 1 und 2 wirst du auch nicht bekommen da du den aux Anschluss nicht verwendest und ich hab da eine Funktion geschrieben da ich ein 24v system habe
der rest sollte aber gehen aber mach mal die “debug victron smart shunt” node an und poste das Ergebnis
PS: wenn du meinen flow 1:1 genommen hast is klar da ich gerade gesehen hab das die Mac und Name garnicht verbunden sind und daher auch nicht ausgelesen werden
OK, habe die Nodes für Batterie1+2 deaktiviert.
Warum kommt aber kein Name und MAC und Typenbezeichnung?
Was bedeutet der Wert RSSI ?
“debug victron smart shunt” ist an. habe es auf Kompletten Nachrichten Object” umgestellt. aber es wird dort nichts ausgegeben…
