I recommend both Sonoff-.branded “ZBBridge-E” and “ZBBridge-P” Zigbee USB dongles from ITead which actually cost less than $20 if you don’t count the shipping + a long USB extension cable. See:
and/or
FYI, you should know while the official Home Assistant SkyConnect USB Stick will be great for early adopters of those wanting to buy new devices using the upcomig Matter/CHIP standard over Thread protocol, the official Home Assistant SkyConnect USB Stick on paper actually performs worse with a large Zigbee network if you will use as a multiprotocol radio with Matter/CHIP over Thread in combination than if you instead buy and use a separate dedicated Zigbee USB dongle. This is totally understandable considering it runs needs to handle the work of two radios, even with the off-loading to System CPU it will do.
So instead consider just buying a separate dedicated Zigbee USB dongle now to use only for Zigbee devices, and then if you want also buy the official Home Assistant SkyConnect USB Stick when it comes out and use that only as a separate dedicated for Matter/CHIP over Thread.
That way you get the best performance and still sponsor Home Assistant by buying their dongle.
There is no point in waiting for Home Assistant SkyConnect USB Stick if want to use Zigbee.
Again, recommend Sonoff-branded “ZBDongle-E” or “ZBDongle-P” from ITead for use with ZHA today:
