@UncleSam der Modbus USB-RS485 Stick ist vermutlich defekt - hab ihn auch an einem PC mit Windows getestet - dort war auch jedes Register 0x00... egal welches Register man abgefragt hat.
Jetzt habe ich ein Modbus-Lan Gateway verbaut, mit dem geht der mobus Adapter im ioBroker wieder... danke.

@UncleSam
Es hanelt sich um einen Stromzähler B+G E-Tech & Eastron SDM530-Modbus, der hängt direkt in der Hauptzuleitung - also mal kurz neu starten ist nicht .
Dann meinst du das es dennoch - trotz der warnungen funktionieren sollte?

Könntest du mir nur zum Abgleich mal deine serialport version sagen? Danke

Hallo Community, ich verzweifle - seit kurzem geht mein modbus Adapter (3.1.10) nicht mehr.
Er updatet die Objekte nicht mehr und verliert ständig die Verbindung - als der Punkt vor dem Adapter wechselt ständig von grün zu gelb.... im "Timeout" Intervall.

Im Log erscheint:

Wenn ich den Adapter entferne und neu installiere kommt folgendes:

Irgendwas mit serialport scheint nicht zu stimmen? Was ist die richtige Version von serialport? Welche soll ich installieren?

Hi, ich hatte das selbe Problem.
Bei mir kamen die Probleme mit der Installation des Adapters "statistics".

In der Browser Console kommt auch ein Fehler - @GeorgS drück mal "F12" wenn du auf der admin-Oberfläche bist.
Dort gibt es eine Console. Dann kannst du uns die Consolenausgabe hier mal posten.
