    egd_brake_disengage_msec:    100
    egd_crc:                     12345467
    egd_drive_max_current_limit: 2

# v0.12.0 and onward:
  - device_class:                 GoldActuator
    elmo_brake_engage_msec:       100
    elmo_brake_disengage_msec:    100
    elmo_crc:                     12345467
