Smart Meter auslesen mit SML Problem

Allgemein

1

Hallo zusammen,

ich versuche mittels ESP8266 meinen Stromzähler auszulesen. Hierzu habe ich in ESP Home die folgende .yaml geflashed.

esphome:
  name: smart-meter-sml
  friendly_name: Smart_Meter_SML

esp8266:
  board: d1_mini

# Enable logging

  password: !secret wifi_password

  # Enable fallback hotspot (captive portal) in case wifi connection fails
  ap:
    ssid: "Smart-Meter-Sml Fallback Hotspot"
    password: blablabla

    filters:
      - multiply: 0.1

Das hat soweit auch funktioniert. Nun sehe ich allerdings in den logs nur am Anfang in lila die Sensoren, jedoch keine zyklischen Updates in türkis, wie üblich.

Ist das doch normal und ich irre mich nur, oder wo liegt ansonsten mein Fehler?

Kann mir vielleicht jemand seine yaml und logs zeigen? Das würde mir schon weiterhelfen.

Vielen Dank!

Ich lese meinen Zähler mit einen IR Lesekopf mit Tasmota aus.
Dazu musste ich bei meinem Zähler erst mal den Pin eingeben und auch die Schnittstelle aktivieren.
Hast Du das bei Dir auch gemacht?

Danke für deine schnelle Antwort. Ja, die PIN hatte ich schon eingegeben.

Es funktioniert leider immer noch nicht. Hat jemand noch andere Ideen?

Das mit Tasmota wäre mein nächster Versuch, falls es mit dem Auslesen per IR Diode nicht klappen wird. Allerdings möchte ich noch nicht so schnell aufgeben.
