Sonoff Zigbee 3.0 Dongle Plus (Coordinator) combined with CC2531 (router)

Hi All,

The Sonoff Zigee 3.0 Dongle plus just arrived and flashed the following firmware on it:
/Koenkk/Z-Stack-firmware/blob/master/coordinator/Z-Stack_3.x.0/bin/CC1352P2_CC2652P_launchpad_coordinator_20220219.zip

I had one CC2531 laying around and installed the router software on it:
/Koenkk/Z-Stack-firmware/blob/master/router/Z-Stack_Home_1.2/bin/CC2531_router_2020_09_29.zip

I installed Zigbee2MQTT and configured everything and tried to add my devices.
My sensors do connect with the Sonoff (Coordinator) and my CC2531 (router) connects with it.

Problem:
All my sensors won’t connect to the router and goes directly to the coordinator.
When I load my map in Zigbee2MQTT I get an error by loading LQI for the router, see image below.

Could someone help me how to connect the sensors to the router instead of the coordinator?

Nobody has an answer for this?
I can’t be the only one right?
