Netatmo: how to calculate daily heating-on time

[Holdestmade]

I use History Stats helpers to do just that as mentioned here:

Hive heating dashboard with custom boost function and heating usage graphs

I just configured it through the UI at Integrations > Helpers > Create Helper then selecting the History helper. More info here - History Stats - Home Assistant I used these for the start and end times which I put in my original post: Daily - start: {{ now().replace(hour=0).replace(minute=0).replace(second=0) }} Weekly- start: {{ today_at('00:00') - timedelta(days=now().weekday()) }} Monthly - start: {{ today_at('00:00').replace(day=1) }} All - end: {{ now() }}
