[Error Joining]: Pilskott Lamp

[lmai95]

After pressing 10s the reset button the device joined but without a working definition. I did try to interview the device but had no luck. Sorry for my German GUI.

Hi, pairing failed. Here are some tips:

Improve your network and try pairing again:

• Update coordinator firmware
  (Use a modern and well-supported coordinator)
• Pair directly through the coordinator (or try other devices, use drop-down on Permit join)
• Power-off 'bad' routers (e.g. Telink Tuya, AwoX)
• Add USB 2.0 extension cable to dongle coordinators
• Change Zigbee channel (find the one with least interference; if possible, stick to the defaults: 11, 15, 20, 25)
• Restart Z2M between pairing attempts

Hey thank for the fast response. I've done some of the things already and will keep the list updated.

• Update coordinator firmware (Use a modern and well-supported coordinator)
• Pair directly through the coordinator (or try other devices, use drop-down on Permit join)
• Power-off 'bad' routers (e.g. Telink Tuya, AwoX)
• Add USB 2.0 extension cable to dongle coordinators
• Change Zigbee channel (find the one with least interference; if possible, stick to the defaults: 11, 15, 20, 25)
• Restart Z2M between pairing attempts

My version information is im Running on a Raspberry Pi 5 with 4 GB of RAM and im using a Tead_Sonoff_Zigbee_3.0_USB_Dongle_Plus

The coordinator update will definitely fix it. You have a 5 year old version.

Stop Z2M, plug into PC and visit SONOFF web flasher.

Actually they have a Home Assistant add-on too. Works as well, but make sure you don't have Z2M and the flasher running at the same time

Thanks a lot updating the coordinator was the right track i did't even know there was a version to update.
