[vz-users] Auslesen eines SMA Tripower X 15-50 über Modbus TCP

Mo Jan 29 16:07:40 CET 2024

Hallo Daniel,

prima. Vielen Dank. Das hat funktioniert. Habe absolut keine Ahnung von 
Node-Red.  Absoluter Neuling.
Ich würde gerne parallel die Daten in Influx speichern. Über das Objekt 
"influxdb out" komme ich das leider nicht so ohne weiteres weiter. 
Irgendwie stimmt wohl das msg.measurement nicht.

Grüße Bernd
