I’ve had some TRADFRI lamps for a while now, and I wanted to add three more. I just can’t get it to work properly 
HA keeps throwing this at me:
2019-03-25 20:08:13 ERROR (MainThread) [zigpy.device] Failed ZDO request during device initialization: Message send failure: EmberStatus.DELIVERY_FAILED Traceback (most recent call last): File "/usr/local/lib/python3.7/site-packages/zigpy/device.py", line 52, in _initialize epr = await self.zdo.request(0x0005, self.nwk, tries=3, delay=2) File "/usr/local/lib/python3.7/site-packages/zigpy/util.py", line 52, in retry r = await func() File "/usr/local/lib/python3.7/site-packages/zigpy/device.py", line 90, in request expect_reply=expect_reply, File "/usr/local/lib/python3.7/site-packages/bellows/zigbee/application.py", line 262, in request v = await send_fut zigpy.exceptions.DeliveryError: Message send failure: EmberStatus.DELIVERY_FAILED
I’m using an Elelabs Zigbee hat for Pi (3)
I have no clue what to do to get my new lamps paired…
