Miele integration: sensor.dishwasher_program_type - any idea what that is for? (it's not for the program type :P)

Despite what the name seems to indicate, this looks like some kind of low-level diagnostic sensor. My guess is it might keep track of the connection to the Miele cloud but I’m not 100% sure.
It is in only one of two states at a time:

  • unavailable
  • normal_operation_mode

Curious if anyone knows what this is actually for.
