Switchbot Bluetooth integration - Outdoor meter - Absolute Humidity

With the Switchbot Bluetooth integration, the Switchbot indoor/outdoor meter can be integrated.
There are 4 entities created with the integration:

  • “bluetooth signal”, which does not work
  • temperature
  • relative humidity
  • the battery

As the indoor/outdoor meter has also “asbolute humidity”, is it possible to have an entity in HA for that absolute humidity?
As a workaround for the moment, I calculate it myself with a template sensor, but it would be easier if it is taken directly from the Switchbot device.
