Esp8266 modbus Jobs
Hatte bisher kaum Berührungspunkte mit Modbus und nun will ich diverse Komponenten in meine Hausautomation einbinden. Allerdings scheitere ich schon beim Auslesen einzelner Adressen. Womöglich habe ich auch nur meine Software und meinen Konverter falsch konfiguriert. Konkret wünsche ich mir eine persönliche Lehrstunde zu Modbus RS485 Idealerweise bin ich nach dem Training in der Lage, einzelne Adressen in meiner Umgebung abzufragen und verstehe, wie ich Schnittstellenkonverter einstellen muss. Zum Testen habe zwei Möglichkeiten, welche ich auch in die Lehrstunde einbinden will: 1. Bestehenden Goodwe Wechselrichter, welcher bereits über eine funktionierende Schnittstelle zu EVCC verfügt und funktioniert 2. Batteriespeicher, welcher über...
