Hier meine geänderte Version für den Shelly 1PM und zusätzlich den Shelly 3EM. Beim 3EM wird die aktuelle Gesamtleistung und die ins Netz eingespeiste Tagesleistung angezeigt. Ganz wichtig ist beim kompilieren vorher unter Arduino IDE bei Werkzeuge den MMU Wert auf(...Heap (shared) zu ändern. Ich hoffe es hilft einigen.
