Configuration

Hello,
I just enabled the fritzconnection tracker to be used along nmap & owntracks, but I am having a repeated error in the log:

16-10-19 14:19:49 homeassistant.core: BusHandler:Exception doing job
Traceback (most recent call last):

raise HomeAssistantError(‘Neither mac or device id passed in’)
homeassistant.exceptions.HomeAssistantError: Neither mac or device id passed in

Has anyone seen this before?

Solved! :slight_smile:
Apparently it was my VPN!!! The tunnel interface shows up in the FritzBox connected devices, but has no MAC address! (Hence the error message in the logs).

If I disconnect the VPN, the error stops as soon as the FritzBox registers it. I suppose the component needs to be updated for this possibility.

This error is popping up as well in my installation. I am using Home Assistant 0.77.3. This is the log:
