Statistic sensor reset/clear at midnight for daily min & max temperature

Configuration
10

To maintain a long-term record of daily/weekly/monthly/yearly minimum and maximum values, I suggest using the Utility Meter integration. It’s how I keep a record of the number of hours my home’s furnace operates (daily, weekly, etc).

For example, if you want to record the maximum daily/weekly/monthly/yearly temperatures:

utility_meter:
  max_temp_daily:
    source: sensor.today_max_temp
    name: Max Temp Daily 
    cycle: daily
  max_temp_weekly:
    source: sensor.today_max_temp
    name: Max Temp Weekly
    cycle: weekly
  max_temp_monthly:
    source: sensor.today_max_temp
    name: Max Temp Monthly
    cycle: monthly
  max_temp_yearly:
    source: sensor.today_max_temp
    name: Max Temp Yearly
    cycle: yearly

The data for Utility Meter sensors is stored in a table within Home Assistant’s database that is retained indefinitely and is not purged every 10 days (or whatever duration you may have set in the Recorder integration).
