Natürlich stimmen die Einstellungen nicht im Script, ich habe ein ESP32 und davon TX2 und RX2 genutzt. Habe das hier noch gefunden... 4-20ma/ModbusMaster#96 (comment) Gruß |

Here is the Link to the Layout I was thinking of a larger version with relay outputs in a larger case. I think that´s the next step |

Hallo, ich bin durch google auf das Thema gestosse! kann ich einfach Tasmota auf esp flashen TX und RX konfigurieren und dann kommen die werte von Epever? Oder muss noch etwas extra programiert werden? Hab einen Tracer und würde gerne die Daten über tasmota auslesen. Danke |

I think I set the voltage to 3.3v, maybe that's why there are no values? |

Where did you get the modbus register information from? I'm also interest in how to set/change the load relay state if that's possible |

Moin zusammen, Stellt man dann in den Einstellungen den TX und RX GPIO ein, erscheint auch die Messwerttabelle im Tasmota. Allerdings sind alle Werte NULL. Hat jemand einen Tipp für mich. Ich habe bereits das komplette Netz durchforstet aber keine Lösung gefunden. |
