eNet radio brightness detector, solar-powered

eNet radio brightness detector, solar-powered

Product code: FMFS1S
The eNet radio system closes the gap between conventional technology, in which devices are wired via a power cable, and networked building system technology. With the eNet Smart Home extension, switching and control of building services via smartphone, local or remote access is possible.

  • Update of the device software
  • Reading of error memory

Sun protection

The sun protection function allows automatic lowering of a blind/shutter in strong sunlight. If a set sun protection value is exceeded for more than 2 minutes, the sun protection sensor transmits the "Sun protection" scene and the blinds move to their previously saved sun protection position. If the brightness falls below the set sun protection value for longer than 15 minutes, then the blind/shutter will move upwards again.

Sun protection, temperature-dependent

Temperature-dependent sun protection can primarily be used in the colder months of the year. The shading of the interior is triggered when the set temperature value is exceeded, in addition to the sun protection value. After triggering the sun protection, the temperature evaluation is deactivated.


When darkness begins, the twilight function allows automatic lowering of a blind/shutter or lighting switching. If the set twilight value is undershot for more than 4 minutes, the "Twilight" scene is opened. If the set twilight threshold is exceeded for approx. 15 minutes, the blind/shutter moves upwards or the lighting switches. To allow the blind/shutter to move upwards automatically, also at dawn, position the sun sensor so that it is not in the shadow of the blind/shutter.
