WaterConsumption not getting updates via MQTT anymore

Hi guys,

since a few days, my Grunbeck water consumption is not updated in the energy dashboard. I used basically the following approach:

and it worked like a charm. Since the last HA update, the Sensor is not updated (or only once a day, maybe when something restarts) anymore. So in ioBroker the values are correct, but the MQTT addon does not get the info in HA. I doubleChecked if the retrain flag is “true” - it is. The debug log gives me two values, one retain:yes, one retain:false - that feels a bit weird. Anyone else has problems?

Sensor Configuration:

mqtt:
  sensor:
    - name: Grünbeck Weichwassermenge
      unique_id: gruenbeck_weichwassermenge
      state_topic: "gruenbeck/0/softliQ/D/BS50020745/Stream/mcountwater1"
      unit_of_measurement: L
      state_class: total_increasing
      device_class: water

Debug-Info MQTT Addon:

    "mqtt_debug_info": {
      "entities": [
        {
          "entity_id": "sensor.grunbeck_weichwassermenge",
          "subscriptions": [
            {
              "topic": "gruenbeck/0/softliQ/D/BS50020745/Stream/mcountwater1",
              "messages": [
                {
                  "payload": "11370",
                  "qos": 0,
                  "retain": 0,
                  "time": "2023-06-15T09:51:02.149635+00:00",
                  "topic": "gruenbeck/0/softliQ/D/BS50020745/Stream/mcountwater1"
                },
                {
                  "payload": "11370",
                  "qos": 0,
                  "retain": 1,
                  "time": "2023-06-15T09:51:03.901483+00:00",
                  "topic": "gruenbeck/0/softliQ/D/BS50020745/Stream/mcountwater1"
                }
              ]
            }
          ],
          "discovery_data": {
            "topic": "",
            "payload": ""
          },
          "transmitted": []
        },

BR and thanks
