SML: Energy Values send to Home assist does not fit to debug values?

Two week ago I have setup reading the values of my electricity meter via ESPHome and SML (Wemos D1 plus Hichi TTL IR). Everything was fine for about 1,5 week. Suddenly the device started sending wrong values for total energy (OBIS Code: 1-0:1.8.0). The other reported values for delivered Energy and Power are still ok. Also the debug values for OBIS Code: 1-0:1.8.0 are ok:

As you can see in the debug log, the sended nonsense value is 1844674360770560.00000 kWh and the debug value for OBIS Code: 1-0:1.8.0 is 0x85ea3a converted to decimal 8776250, which is correct.
This is the sensor definition:


  • platform: sml
    name: “Energie bezogen”
    sml_id: mysml
    obis_code: “1-0:1.8.0”
    unit_of_measurement: kWh
    accuracy_decimals: 3
    device_class: energy
    state_class: total_increasing
    • multiply: 0.0001
    • median:
      window_size: 5
      send_first_at: 5
    • throttle: 300s

Can anybody explain, why the sended value ist totally different from the debug value?
