Pulling my hairs out: why is it impossible to add an additional Zigbee device?

Am running a Zigbee network on Conbee 2 with 9 devices (6 hue lightbulbs, 1 Tradfri bulb and 2 Aqara sensors). I have been trying to add devices to the Zigbee network (hue wall plug, hue lightsbulbs). Pairing works flawless but < minute after pairing they will become unresponsive. I have reset all devices to factory state, tried pairing/unpairing them to Hue bridge, updating the firmware, rebooting the server etc. Every time it is the same: the initial 9 devices work perfectly and all newly paired devices are unresponsive. Can anyone tell me what I am doing wrong? Find below the log of me re-adding a new device ( LWA017) and becoming unresponsive.

New device 0x7b2f (00:17:88:01:0b:36:5b:23) joined the network

Are you running the latest firmware of the conbee stick it’s self? (Update via an external system)

Yep! Updated it this week with deCONZ_ConBeeII_0x26720700.GCF right from: Index of /deconz-firmware/

Weird indeed. I had some luck with right clicking (can’t remember as I am offline from hass) in deconz while “repairing” the device. So do not exclude it but repeat the inclusion on the device while right clicking and pressing (what I forgot). Some devices seem to need more time to be fully discovered (at least that was my problem with some).

Try and If you can’t find let me know and when possible I will make screenshots.

This sometimes happens to me and the solution for me is to do a reboot of the host os, then try repairing again and then the pairing usually sticks.

I already rebooted the host multiple times, without any success. Now the weird part; after I powered down the entire house (needed to change some wiring) I tried again and successfully managed to add 4 additional lightbulbs without any problem. System is running stable and expected since then…

Hate these kind of mysterious solutions, but it is what it is :slight_smile:

Actually, I should have mentioned that while rebooting I also unplugged and reinserted the USB ZigBee dongle.
