6 Devices Limit?

[matogewabe]

Hi,

We setup a new zigbee network with z2m and initially it looked very good. But after including a few devices, we had trouble to include more than 6 devices per zigbee router device. If a router device is connected to 6 non-router devices, it just refuses to either include new, or even connect to devices already included but temporarily disconnected.

We added some additional router devices hoping that this would at least allow us to include all our devices, but something still seems off, as there are lots of disconnects etc.

Is this some kind of hard limit or is there any setting I can change to be able to connect to more devices?

thanks in advance,
Manfred
