Energy dashboard - negative spike every start of the day

[sender]

hi all, merry christmas!

I hope I can get some warm help on a long lasting problem… an energy dashboard spike. Every day.

I described it here and maybe several other places (discord) but never got it solved.

Energy Integration Spike

Try to check for the availability of your energy sensors. This is an example code: total_solar_energy: value_template: "{{ ( states('sensor.total_yield')|float + states('sensor.total_yield_2')|float ) | round(2) }}" availability_template: "{{ states('sensor.total_yield') not in ['unavailable', 'unknown', 'Unknown', 'none'] and states('sensor.total_yield_2') not in ['unavailable', 'unknown', 'Unknown', 'none'] }}" device_class: 'energy' …

The problem is as follows:

Every start of the day I have a negative spike as big as the total gen of the day before.

the sensor comes directly from esphome (modbus:

sensor:
  - platform: growatt_solar
    energy_production_day:
      name: "${esp_name} - Today Gen"
      id: todaygen
      filters:
         lambda: |-
            if (id(inverter_status).state != 0) {
                return x;
            }
            return {};

Also resetting it every night did not help:

time:
  - platform: homeassistant
    id: homeassistant_time
    on_time:
      # Every morning on weekdays reset ID todaygen
      - seconds: 0
        minutes: 0
        hours: 0
        #days_of_week: MON-SUN
        then:
          - lambda: id(todaygen).publish_state(0);

There is no need to keep creating new topics about this. The answer is the same as last time:

Energy dashboard not populating

This is not normal behaviour for an inverter. The integration needs to be fixed or the inverter settings need to be changed. e.g. SMA inverter: [Untitled]
