Re-adding motion sensor to Deconz "not reachable"

Hi guys,
I had some problems with one of my motion sensors so I decided to re-add it to my Conbee 2 via de Deconz web app. I removed the sensor first and then tried adding it again. After a lot of tries it finally detected the sensor, but then it only shows this:

I’m not getting any data from the sensor.
