Lost device : Fibaro Door sensor

[galinette]

Hi,

Since yesterday, my Fibaro Door Sensor is not updating anymore in Domoticz.

In the ZWave node list, it's marked as "sleeping" (moon icon). I see it has not been seen since 36h, while the Wake-Up interval is 12h, and I've opened an closed the windowseveral times. However, when moving the window, the sensor led reacts as usual to show it is sending state change.

Also, in the network topology, it's not connected to any node.

I have tried to start a network heal yesterday, and tried to open and close the window to trigger updates, without success.

What can I do?

Thanks!
