maconline not working

[Torsten555]

Hi,

I am using Openhab v. 2 together with the Fritzboxtr064 binding v1.13.0.

The maconline functionality is not working for me even though that MAC is online also shown online in the WebUI:

Item configuration:
Contact cFboxMacOnline "Presence (WiFi) [%s]" {fritzboxtr064="maconline:11-22-33-44-55-66"}

With debug logging enabled, the following message shows up in the logs:
2019-01-14 22:45:53.232 [DEBUG] [ing.fritzboxtr064.internal.Tr064Comm] - MAC not known to FritzBox!

I have tried different devices with their MAC addresses, all of them showing online on the UI. I have also tried deleting the device on FritzBox's webUI but it did not help either.

Any further ideas?

Best, Torsten
