Da mir die stetigen Spitzen in meinen Werten auf den Keks gehen, habe ich mal angefangen den ESPLesekopf von Tasmota auf ESPHome umzustellen.
Dank GitHub - mampfes/esphome_obis_d0: esphome external component to support meters with OBIS D0 interface sollte neben SML auch D0-Obis möglich sein und die Sensor-Filter um “nan” “0” und andere Fehler vorher rauszuglätten.
ESPHome Firmware lässt sich auf dem esp8285 manuell über die Tasmota Firmware flashen, insofern ist der Wechsel relativ angenehm.
Warnung vorweg: Work in Progress.
Es kompiliert, aber es gibt noch keine Werte.

Sobald ich da Werte rausbekomme dürfte Statistiken in Home Assistant korrigieren (Energie Dashboard) nicht mehr in der Häufigkeit notwendig sein.
