Edit: ah I'm an idiot, it's a zigbee + z-wave, not matter dongle! Derp. I added matter at the same time and mixed the two up.
~~I grabbed an Aeotec Z-Stick 10 Pro a few months ago, although I can't run Matter over wifi (with my sole device that supports matter) since I can't get an ipv6 address from my isp. But I figured it would be useful down the line as matter/thread gains popularity. I already had several Zigbee devices so future-proofing my setup. And I'm running ha off a proper server now, but that could change, so having less occupied usb ports is handy.~~
~~I transferred my existing zigbee network to the new dongle and after some moderate troubleshooting (I have proxmox, VM passthrough, plus HA to deal with) I had it moved over and unplugged the old dongle, and everything continued to work.~~
