Enable old discovery method - what is the difference?

[cguthardt]

Feedback

Site tells you to enable the old discovery method in some cases. But I can't find any documentation on what the differences are between the old and new discovery methods. What disadvantages do I get by enabling the old method? There must be something, or it wouldn't have been replaced by a new method. Also, does changing the discovery method from new to old re-discover all devices, maybe ignoring name changes that I did and breaking automations?

I got to this because I am experiencing this problem with FritzOS 8.0

[mib1185]

The new (and default used) method is based on the mesh topology data of the fritzbox and has some advantages like you know via which mesh-device (fritzobx or repeater) your device is connected.
But this mesh topology data don't work correct on non-meshed setups or when there are 3rd party network devices involved (eq. switches or non-AVM access points).

[cguthardt]

Understood. So I have the choice of benefiting from this fix and being able to track the access point of my device, OR being able to have automations based on whether LAN devices are turned on or not.

Is it known if the fact that I have switches on my network will ruin the whole enter/leave detection of LAN devices or will it work as long as the LAN device is directly connected to a Fritzbox (or a secondary Fritzbox that is connected to the master via a switch)?
