What is the difference between license and device?

A license is the entity that maintains all the licensing parameters (features, limitations, expiration date). One device can control 1:n devices. Examples:

  • 1 license with 3 devices for development-testing-production environments.
  • 1 license with 100 devices, controlling 100 sensors in a sensor network.

Change management is the main advantage of having a license (master) controlling multiple devices. Upon a license-parameter change, only the master license has to be updated.
