A passing thought, There is an option in the Fritz menu>Home Networking>device Name to change the name of each Fritz device to make them more easily identified in the network.
I don't believe this would affect the mesh SSID being the same but may allow you to use Fing on your android device to identify the repeater vs the master ?
Then, knowing the source devices and knowing the stronger signal (from info on other devices) you could choose the SSID that applies. ?
note--- that there may be breakage to other already setups and you may have to reconfigure them. See the warning in the Fritz Menu when changing device names.
