Hallo,
ich habe eine Shelly 3EM mit Tasmota geflasht. Verbindung steht. Möchte aus dem Telegramm die einzelnen Werte heraus lesen.
Ich abe eine Problem der "incomming Value Transformation" von dem MQTT-Telegram

Parametrierung:

Offensichtlich ist die Transformation falsch. Habe da schon unterschiedliches probiert, komme aber nicht zum Ergebnis.
Ich möchte z.B. den Wert Current : 0.781 auslesen.

Vielen für Eure Hilfe.

Moin,
versuch mal transformationPattern: JSONPATH:$.ENERGY.Current[0]

Moin Harka,
