Volvo On Call sensor description improvements

Hello

I want to suggest two improvements to the default binary sensor descriptions of the Volvo On Call integration to improve their presentation:

Change binary sensors with device class “safety” to “problem”.
To me it makes more sense for the following sensor to be either in a OK or problem detected state, instead of them being in a safe or unsafe state:

  • Brake Fluid
  • Bulbs
  • Front left tire
  • Front right tire
  • Rear left tire
  • Rear right tire
  • Service
  • Washer fluid

Use specific icons.
There are specific icons available for a lot of the binary sensors for both their on and off states:

  • Brake Fluid
    OK: mdi:car-brake-fluid-level
    NOK: mdi:car-brake-alert
  • Bulbs
    OK: mdi:car-light-high
    NOK: mdi:car-light-alert
  • Front left tire, Front right tire, Rear left tire, Rear right tire
    OK: mdi:tire
    NOK: mdi:car-tire-alert
  • Washer fluid:
    OK: mdi:wiper-wash
    NOK: mdi:wiper-wash-alert

Additionally:

  • Service:
    ANY: mdi:wrench-clock
  • Engine, if the vehicle is not electric
    ON: mdi:engine
    OFF: mdi:engine-off
