The outdoor luminosity is mainly used for lighting control systems and shading management, taking the position of the sun into
account. It can also be used as a display on touch screens.
The luminosity value is periodically sent every 30 minutes and at each change if the variation is greater than 20 % compared to
the last measurement.
The threshold is fixed at 10 Lux (fixed value), with a hysteresis of 2 Lux (fixed value).
The information is sent 2 times every 24 hours (switching from day to night and night to day).
The day/night information operates as follows:
-
The "Day" information is activated (bit = 0) if the value measured is greater than the threshold value + hysteresis (12 Lux)
for more than one minute (fixed value).
-
The "Night" information is activated (bit = 1) if the value measured is less than the threshold value (10 Lux) for one minute.

Links
For this function, the link is made automatically if compatible products are present in the installation.
This automatic link is used by twilight switches. They have a luminosity, master and slave channel.
The domovea supervision system also uses this link but only for the slave channel. Products are in slave mode by default. They
switch to master mode when a luminosity probe is connected to the product.
Note: The presence of the weather station implies that the twilight switch does not require a probe. A single luminosity probe is
sufficient.
