        In LibreNMS it equals to 3 state sensors:
        Closed commutator: Mains or Genset (what commutator is closed, so where the power comes from)
        Genset Mode: Block, Test, Manual, Auto (the 4 modes of the genset)
        Alarm: Yes or No (If there is a commutator alarm)
        Example:
        Value = 66
        Value binary = 1000010
        States equals to:
        - Alarm: No active alarm
        - Genset Mode: Auto
        - Closed commutator: Mains
