Openweather Sensor - Change unit from mbar to hPa

I have configured the open weather map sensor like this:

  - platform: openweathermap
    api_key: befca02e068f123451234567890
    monitored_conditions:
      - temperature
      - pressure
      - humidity

I assume the two graphs in the history card is caused by the different units.


How could I modify the unit for pressure from mbar to hPa?

Basically mbar and hPa is the same value, so the difference is not related to the unit used, but more likely how often the value is updated.

1000 hPa are equal to 1000 mbar , which is equal to 750 mm of mercury in a barometric column, which is 0.987 of the average atmospheric pressure, which on global average is 1013 millibars or hectopascals. While hPa is used in meteorology most weatherforecasts quote atmospheric pressure in millibar .
See https://www.weatheronline.co.uk/reports/wxfacts/Millibar-and-hectopascal.htm

I assume not, because the stacking of the temperature or humidity values from the same two sensors works well.

Did you find an solution to this? I face a similar issue with W (Watts) and VA (reactive power) which I would like to see in the same graph.

Not really.
Unit is still mbar.
But I switched to the mini graph card: Values with “Gemessen” are hPa and “Vorhersage” uses mbar.
