Agree. I am also using a longer cable and it seems much better now…
But everything seems to break for me with the December updates.
Hi,
I am new with the skyconnect,… Try to bind the LYWSD03MMC whatever with the original firmware or the Tellink… No luck… actually with ? Any tips ?
frist thing I would say is try a longer cable and keep the dongle as far away from the usb3 ports as possible.
not sure why you are messing around with fw at this stage. suggest to keep orinal for now.
I also had issues with OS9 and later. working well for me on OS8.5
I already tried with an extension cable (+2m)… still nothing 
…
same problems here with the skyconnect and a rbp4
My SkyConnect started to work properly after I relocated my rpi4 with HA to a different room in the house (too much interference in the hallway fusebox cupboard??) And using a 1.5m extension cord allowed downstairs Zigbee outlets to be detected instantly.
i just ordered a couple of extension cords. my rpi4 is in the hallway fuse box cupboard as well.
i got cables of 1.8, 3 and 5 meter. I now using z wave and i got recently buy 2 zigbee wall dimmers because i dit ordered the sky connect. we’ll try again later this week
Hi,
first I’ve fist had Problems too but then used a longer cable and instead of the USB 2.0 Port side by side of the always in use USB 3.0, I used the USB 2.0 diagonally. All this is on my Raspi 4, Home Assistant in a Docker.
Now at least 98% of my network us working. (1 Device is disconnecting and I have to investigate what triggers the leave and one is not configurable, both should be software and not physics)
I also tried to switch from Devons Stick to SkyConnect, also used a longer cable than before but it can not find any devices for me. The Devons Stick is finding the devices without problem. I tried several restarts, removing and adding integrations without luck. So I will stick with Devons for now I think.
my skyconnect is working now.
I used a cable of 3 meters en it finding my devices at once and have now 2 day’s perfect working.
First attempt at migration from Raspbee II was a partial success, some devices working, but some not. I added a 2 meter cable and now all but except Sengled bulb and an Ikea blind are working. (Both of those had been giving occasional problems on the Raspbee.) However, I’m having trouble adding new devices. The only way I could get an Aqara motion sensor to pair was to put it right next to the SkyConnect stick. Now that it’s paired it seems to be staying connected even when moved away.
I came to this thread because my SkyConnect was not finding any devices either. Even when moving them close to it. I can confirm that adding a longer cable works (I used a 3m long extension cable, but that is probably overkill - I just used it because it was the only one I had lying around 
).
@pkerobinson - the Aqara devices are notorious for having connection issues (they seem to not be fully compliant with Zigbee standards). I have had many issues with them in the past (using zigbee2mqtt), so I have very low expectations that they would work with SkyConnect. I literally have Aqara devices that I am completely unable to pair - no matter how many times I try to reset them, they are never detected.

I have all Aqara and IKEA Zigbee devices and until Dec 2022 I successfully used a Conbee II stick;
After some HA updates these suddenly stopped working. I tried everything, downgrading, fresh installs, upgrading firmware, buying a SONOFF ZBDongle-P, then ZBDongle-P and finally the SkyConnect Dongle and NONE of these worked for me.
After scouring forums and hearing about using longer extensions I found an old USB hub with a 2 metre lead, and like magic all the dongles worked and everything paired (face palm). I still have no idea why this is now the case but it is the solution to which I have to resort.
Apologies for the rant but this is the solution which works for me now - any USB extension lead 2 metres+.

I just migrated radio from (zha) deconz ii to (zha) skyconnect.
Managed to get everything to work but not the ikea tradfri bulbs. Flashes fine and pairs and the sort of kicks it self out. Seems to go back from grey to color icons but there is no reaction from
the bulb.
Any known issues?
Same issue here. Migration from Conbee 2 to SkyConnect was fine, but adding new IKEA devices fails. It seemingly connects but then immediately drops off. Existing IKEA devices that were migrated from the Conbee 2 through ZHA work just fine.
There is definitely something wrong with the Skyconnect stick. Migrated back to Conbee II and added the troublesome units and now everything works as it should. The zha_event fires as they should now so my automations started to work as well.

Could it be that the Ikea Tradfri bulbs became unstable after the latest update? It was working fine for me until I updated yesterday.
I’m not able to use SkyConnect with ZHA. → connection failed error in the last config step.
Any ideas?
