Usage
If you select Sensoface , all Sensoface messages are output via the selected contact.
If you select Sensoface (Channel) , you can output the Sensoface messages from a specific channel via
the selected contact.

Note: The worsening of a Sensoface criterion leads to the devaluation of the Sensoface indicator
(Smiley gets "sad"). An improvement of the Sensoface indicator can only take place after calibration or
removal of the sensor defect.
