  Open Rowing Monitor, https://github.com/laberning/openrowingmonitor

  This manager creates a module to listen to ANT+ devices.
  This currently can be used to get the heart rate from ANT+ heart rate sensors.

  Requires an ANT+ USB stick, the following models might work:
  - Garmin USB or USB2 ANT+ or an off-brand clone of it (ID 0x1008)
  - Garmin mini ANT+ (ID 0x1009)
