Incorrent values in energy dashboard when reconnected smart plug

[dknt]

Hi,
I’m looking for some advise on finding a root cause and how to fix a problem I faced.

Scenario:

1. Smart plugs with esphome and energy sensor.
2. Disconnected the plugs for 3 weeks.
3. In the meantime Home Assistant was restarted (power outage).
4. When plugs were reconnected, in the Energy dashboard I see hundreds of kWh negative for sensors of these plugs.

Details:

1. Plug models: Blitzwolf SHP6, Gosund SP111.
2. ESPhome config of the sensor:

  - platform: total_daily_energy
    name: "${plug_name}: Dzienne zużycie energii"
    power_id: "${plug_id}_Wattage"
    filters:
        # Multiplication factor from W to kW is 0.001
        - multiply: 0.001
    unit_of_measurement: kWh
    state_class: total_increasing
    device_class: energy

3. Energy dashboard for the problematic day:
   
   
4. History graph for an energy sensor of one of the plugs:
   
   
5. Dev opts entity state:
   

Any idea what happened?
