Functional description
Send switch status response (Object "Switch/Status")
Option: no
only if value change
always
With this parameter, you define if and under which conditions the
switching status of the device should be sent via the "Switch/Status"
object
No status is set with the setting "no" (default value).
The option "only if value change" has the effect that the switching status
is only sent with a status change from ON to OFF or from OFF to ON. As
the switching status can be changed via different functions, e.g. central
control, slave mode, scene retrieval etc. and the 64 devices can only be
scanned cyclically, a status message delay can result.
The option "always" has the effect that every received telegram which
can change the status triggers a returned status message detailing the
current state. It is possible that delayed status messages can occur in
this case e.g. after a central command all devices respond in succession
even if the status has not changed.
Send brightness status response (Object "Brightness value/Status")
Option: no
only if value change
always
With this parameter, you define if and under which conditions the
brightness value of the device should be sent via the "Brightness
value/Status" object
No status is set with the setting "no" (default value).
The option "only if value change" has the result that the brightness value
is only sent if it is changed. The feedback only occurs if the brightness
value deviates from the previous value at the time the cyclic scan occurs.
This reaction allows the visualisation of a chronological brightness
characteristic. As the brightness value can be changed via different
functions, e.g. central control, slave mode, scene retrieval etc. and the 64
devices can only be scanned cyclically, a status message delay can
result (the time delay can be over 90 seconds).
The option "always" means that a status message of the current state is
sent each time a telegram is received. It is possible that delayed status
messages can occur in this case.
