Peaks at summed time statistics

Configuration Frontend
1

Hello,

I would like to have the runtime of my underfloor heating displayed per day. I have already created a sensor for this, which actually works:

  - platform: template
    sensors:
      heizung_esszimmer_on_off:
        value_template: "{{ state_attr('climate.smart_thermostat_123','hvac_action')}}"
  - platform: history_stats
    name: Heizung Esszimmer Laufzeit
    entity_id: sensor.heizung_esszimmer_on_off
    state: "heating"
    type: time
    start: "{{ now().replace(hour=0, minute=0) }}"
    end: "{{ now() }}"

The time is correctly displayed in a map:

But when I look at the statistics, I keep seeing peaks there that shouldn’t actually be there, since the time is commuted. This value should not decrease within one day.

Is the error in my code? Or what could be the reason?

Thanks
Loki
