I added a device via python script: https://github.com/dsteinkopf/dbus-dtu-ahoy
This is working fine: It is shown in the GX device, the console, in the VRM Dashboard and in the device list under "advanced". So also the corresponding widgets for the new device are shown correctly.
But under "Device list" the device is missing. Also, when I try to add a custom widget under "Advanced" the new device is not shown.
What am I doing wrong? What could I check?
