Probleme mit Modbus TCP Carlo Gavazzi EM24

Allgemein
1

Ich versuche einen Carlo Gavazzi Zähler EM24-E1-AV2 X in HA einzubinden.

Dazu habe ich die config. yaml um diese Einträge erweitert.
Zum Test nur mit einem Sensor:

modbus:
  - name: EM24
    type: tcp
    host: 192.168.1.10
    port: 502
    sensors:
      - name: EM1 Phase 1 voltage
        address: 0
        slave: 1
        unique_id: em1_phase_1_voltage
        data_type: int32
        device_class: voltage
        input_type: input
        precision: 2
        scale: 0.1
        state_class: measurement
        swap: word
        unit_of_measurement: V

Im homeassistance.log bekomme ich folgenden Fehler:

2025-07-06 16:22:31.047 WARNING (SyncWorker_0) [homeassistant.loader] We found a custom integration hacs which has not been tested by Home Assistant. This component might cause stability problems, be sure to disable it if you experience issues with Home Assistant

Was mache ich falsch?

Bin dankbar für jeden Tip.
Möchte im nächsten Schritt mehrere Zähler einbinden.

In der Konfigurationssoftware von Carlo Gavazzi UCS7 funktioniert die Verbindung:

Auch mit Open Mod Scan kann ich die Register lesen:

Probier es mal hiermit.
Das sind alle Sensoren die ich mir im Internet zusammen gesucht habe. Bei mir funktionierts.

Wenn du Vorschläge zur Optimierung hast, immer her damit.

Danke!.
Ich habe das Problem gefunden. Zu peinlich.

Es war zwei mal die gleiche IP im Netzwerk.
Erstaunlich, dass die Herstellersoftware und Open Mod Scan keine Probleme hatte.

Alles gut!

Auch wenn der Beitrag schon gelöst ist bzw auch etwas älter, aber eventuell für den Ein oder Anderen interessant.
Ich bekam mit den Werten keine plausiblen Daten, daher habe ich nochmal genauer nachgeschaut und bin nach dem PDF gegangen, welches für ein EM24_E1_CP gilt:

Danke tugsi,

ich werd’s bei mir auch mal so einbinden. Habe noch nicht viel gemacht seit ich eingezogen bin.
