Pairing of new devices does not work, but functionality otherwise is fine

Configuration Zigbee
1

Hi all,

I am using the Zigbee2MQTT add-on and I have roughly a dozen devices that I have running. They work fine. I am running version 1.15.
My problem now is that I can’t pair new devices. I am trying a Tradfri on/off switch without any luck. I have tried a Xiaomi door & window sensor with no luck and the same for a Xiaomi temperature and humidity sensor. Here is my config, I am lost to be honest (I haven’t tried pairing in a year or so and I updated, so not sure if it is related):

data_path: /share/zigbee2mqtt

I someone seeing the problem in the config potentially?

Anyone with any help? It drives me nuts, I’ve tried again tonight with no luck. I almost feel like there have to be outside effects that prevent me from pairing.

From the Zigbee2MQTT faq :

CC2531/CC2530 coordinator only:

Stop Zigbee2MQTT, unplug the coordinator, wait 10 seconds, plug the coordinator, start Zigbee2MQTT and try to pair the device again.

Yeah, I tried that as well to no avail. I have a lot of Philips Hue in the flat, they are operated by the Hue bridge, but we are well above 50 Zigbee instruments, could this make the difference despite the fact that the coordinator is not responsible for them?

Would a conbee stick be better suited?
