You can have a look at the global translation table.

As described on our wiki[1], there you find all the
_clients_ announced by each node in the network. The problem is that if a node
has other clients connected to the mesh through a bridge, than you will see
many entries corresponding to the same node and you will not be able to
distinguish bat0's macc address from other clients.
