Hello,
I have linked my presence sensor with a switch item, but this switch doesn’t switch.
Here my events.log
2020-01-18 15:12:08.076 [ome.event.ItemUpdatedEvent] - Item ‘Sensor_1Floor_Presence’ has been updated.
2020-01-18 15:20:38.981 [vent.ItemStateChangedEvent] - Sensor_1Floor_Presence changed from NULL to OFF
How can I fix this?
Thank you for your help.
Would you show us how you think you have linked your Item to a switch, as that is the part you say is not working?
Yes: 
The profile is default
Your events.log shows the appropriate Item being updated to OFF.
Perhaps you could tell us more about what doesn"t happen, that you expected to happen.
I want that the Senor Update to ON and not to OFF when somebody moves
I don’t know anything about Deconz. Maybe update your thread title to attract the right attention.
This thread may have some clues
It works now thanks.
