How to add Zigbee Router to existing Zigbee2MQTT Network

I was wondering if there is any trick incolved in adding an additional router to the network!?

I currently have 1 coordinator (CC2530):
zigbee2mqtt:info 2019-3-2 15:51:03 Starting zigbee2mqtt version 1.1.1 (commit #unknown)
zigbee2mqtt:info 2019-3-2 15:51:03 Starting zigbee-shepherd
zigbee2mqtt:info 2019-3-2 15:51:04 zigbee-shepherd started
zigbee2mqtt:info 2019-3-2 15:51:04 Coordinator firmware version: ‘20181122’

And 4 devices connected:
zigbee2mqtt:info 2019-3-2 15:51:04 Currently 4 devices are joined:
zigbee2mqtt:info 2019-3-2 15:51:04 0x00158d0002c9065d (0x00158d0002c9065d): WSDCGQ11LM - Xiaomi Aqara temperature, humidity and pressure sensor (EndDevice)
zigbee2mqtt:info 2019-3-2 15:51:04 0x00158d0002c7d754 (0x00158d0002c7d754): WSDCGQ11LM - Xiaomi Aqara temperature, humidity and pressure sensor (EndDevice)
zigbee2mqtt:info 2019-3-2 15:51:04 0x00158d0002c906b9 (0x00158d0002c906b9): WSDCGQ11LM - Xiaomi Aqara temperature, humidity and pressure sensor (EndDevice)
zigbee2mqtt:info 2019-3-2 15:51:04 0x00158d0003278dec (0x00158d0003278dec): 404006/404008/404004 - Müller Licht Tint LED bulb GU10/E14/E27 350/470/806 lumen, dimmable, opal white (Router)

Now I bought an additional CC2530 and flashed the Router FW. When I connect the new CC2530 router to the power, and enabled joining of new devices:

zigbee2mqtt:info 2019-3-2 15:51:04 Zigbee: allowing new devices to join.

But for some reason I am not able to see the router anywhere…

Hi,
I have same problem.
Coordinator is CC2531 and working fine with several devices.
I bought few CC2530 boards with external antennas. I can flash router firmware (cc2530_router_2019_02) to all these cc2530 boards with SmartRF04EB, can get verifications, read IEEE via SmartRF flash programmer, but any of these cc2530 routers are visible in HA Zigbee2MQTT logs or network.

Any tips or help here?

It took some time, but at some point the Router worked:

zigbee2mqtt:info 2019-3-2 17:10:13 Device incoming…

What I did was extend the period devices are allowed to join to 60mins and also restart the whole raspberry… Then I left it running and looked what happened.

Hi,
How can you check if sensors connect to router or connect to a coordinator directly?
Thank you

You can try the zigbee2mqtt network map, but it is not very accurate (I have some orphaned sensors that work splendid)
