Zigbee Devices Not Responding After Migration from C5 to C8

Hey everyone, I’m facing a puzzling issue with my Zigbee devices after attempting a migration from my C5 hub to a C8 hub. I decided to stick with my trusty C5 hub since it was working perfectly, and the C8 upgrade wasn’t worth the extra cost for me. However, after unplugging the C8, I noticed that all my Zigbee devices stopped communicating with the C5 hub. Everything else, like my Sonos speakers, Lutron remotes, and Philips Hue bulbs, worked fine. It’s just the Zigbee devices that are unresponsive now.

I tried resetting some of the devices and pairing them back to the C5 hub, but it didn’t work. For example, my ST buttons wouldn’t pair properly—they’d show as detected but then time out without being added. I’m wondering if this is a known issue or if anyone has experienced something similar after migrating from C5 to C8. Any insights or suggestions would be greatly appreciated! :blush:
