I have a coordinator and 2 routers (both CC2530 + CC2591) Firmware: Zigbee2mqtt 1.14.1
The first router is working fine and I see 3 Entities under the device. The router, Link quality, and LED,
For some reason the second router only showed the Link quality and LED entities in Devices. The top row was missing. I tried deleting it from Devices in HA and restarting the router hoping it would re add it but now it doesn’t show up at all. I do see it in the Zigbee2mqtt log writing this every minute:
I managed to get it to show up in HA Devices by force removing and reflashing the firmware. But I’m back to the original issue that only the LED entity comes in not the Router.
In MQTT Explorer I see the same thing. The 6406e is only publishing a LED message where the 107f is publishing both a router message and an LED message.
as already answered, no securty issue, but two comments
If you asked your question, your network is probably not secure. Using a secret network key, not keeping the default one is what will encrypt the zigbee payload.
I recommend using friendly names that might make your debug sessions easier
When it comes to your issue, maybe they need sometime to start reporting their attributes or the pairing did not happen properly, you could try to pair them in closer location to check if they work properly before setting them back on their final position, also if you have lots of noise you might want to chose a clean channel by checking if the freq is far from your wifi channels.
I fixed it. Installed zigbee2mqtt 1.7.1 on a spare SD, and the CC2530 was recognized as a router. Even when I switched back to 1.14.1. Did not even have to re-pair.
