Hallo Forum,
ich brauche bitte euere Hilfe.Ich experimentiere mit einer LED Matrix.Es sollen Werte von einen Wechselrichter(Lumentree 600) mit Trucki Stick auf der Matrix angezeit werden.Mqtt Verbindung funktioniert, Werte kommen an und auf der Serial Ausgabe angezeigt.
Aber wie kann ich die einzelnen Werte rausfiltern und einzeln anzeigen(Serial Konsole)?
Zu Beispiel T2SG418981/VBAT - 26.00 zu T2SG418981/VBAT - 26.00 Volt einzeln ?
Grüße-Martin
