Request for new device type for Binary Sensor

If possible, I would like to see a new device class created for binary sensors.

Something like…

  • activity: on means active, off means idle

One example I have is my binary_sensor.my_pc_is_active. I currently am using moving but the state display for on/off does not describe PC activity and is more indicative of the power state, which is inaccurate as this activity sensor turns off input_number.pc_active_timeout seconds after the PC is not being used. I have a different sensor I use for the PC’s power state.

Thanks for your consideration!
