Zigbee binding / Ember stick: Tradfri bulb doesn't get discovered

I have bought this Zigbee dongle. It’s an Ember coordinator based dongle.

I’ve connected the dongle to my Raspberry Pi with OpenHabian 2.4.0. After some fiddling with the settings, I got the dongle working. It shows up “online” in the Paper UI.

The next step is having my bulbs and switch discovered. However, I’m not very successful with that. If I put the Zigbee binding in discovery mode via the Paper UI, I see in the logs that the discovery is started:

Starting ZigBee scan for zigbee:coordinator_ember:60e947383cc73b40b82a169ed7abb498

However, nothing happens. I understand that the bulb has to be reset by powering it off and on again, so I did. I tried different orders: first starting discovery, then powering up the bulb or the other way around. Whatever I do, nothing happens.

Is there anything I can do to get an idea of what is going on? Or do I have to do additional things to properly reset the bulbs before it can join the ember network? I hope someone can help me with this.

I think to reset the bulb, you’ve got to do more than just power it off and on.

Thanks Chris! Could have Googled that myself… I will try this soon and let you know the results!

Hi Chris,

Thanks for linking to that Youtube movie from Ikea. As shown in the movie, the trick is to power cycle the bulb 6 times. Then it is reset and it can be discovered. I’ve successfully added 3 bulbs to my OpenHAB setup now!

Best regards,
