-This section extends the [=automation=] section defined in the Generic Sensor API [[GENERIC-SENSOR]]
-to provide mocking information about the proximity level for the purposes of

+This section extends [[GENERIC-SENSOR#automation]] by providing [=Proximity Sensor=]-specific virtual sensor metadata.
