DALI2 sensor parameters

[Novodk]

Is there any documentation regarding DALI-2 sensors, specifically the movement parameters?

[Daniel]

All this is representation of DALI 2 standard, what is particularly not clear? Movement is only about reporting a movement

[Novodk]

If you choose everything you get 2 ga, Movement detected and Occupancy detected!
Is movement then 1 when there is movement and 0 when there is no movement? And if you only have "Movement" checked then it only sends 1 when there is movement?
Vacant and Repeat are doing what?
Report timer? (Repeat?)
Occupancy is using the Dead time and the Hold timer?

Depending on the sensor type you can get two different events for movement and occupancy. For simple movement sensors you can use either event.

Hold timer defines the movement timeout. When movement is detected the timer is started/restarted again. This does not apply for presence sensors where movement state is reported as soon as possible and hold time is not used at all.

Dead time controls the total time between each event telegram on the DALI bus. If it is set then the device won't send any events until the timer expires. This is meant to lower the bus load.

Report timer sends the current event state (occupancy/movement) every X seconds even if no new event has been generated.

If enabled, repeat generates "Still vacant"/"Still occupied" events which are controlled by the report timer. We don't expose these type of events separately, the same occupancy object is updated with the corresponding value.

How do we know if hold time is used on the movement object?

You can check it manually. Trigger a movement and see when the movement detection goes to 0 in the DALI app monitor.
