Installed 9 Blues yesterday as multi-way smart-to-smart switches. They worked great - until I packed them back into the wall. Then 2 of them stopped responding at all to any updates from bound switches, and stopped updating the switches to which they were bound. 100% failure rate on those 2 switches.
Found this thread - it’s unclear which ranges are impacted (is it all 38.xx and 94.xx ranges, or just 38:5b:44:ff:fe:ee and 94:34:69:ff:fe:08?)
6 of my 10 switches are 38.xx or 94.xx, but only 3 are in the more restrictive ranges. 2 of those 3 aren’t working for me at all.
By the way, for SmartThings users on the Edge drivers - you can view the EUI/IEEE address digitally by digging through “Switch to Bulb(s)” → “Smart Bulb(s) Wired to Smart Switch” → “Smart Switch to 1x Smart Bulb” → “Written Instructions” → “Getting the Zigbee ID” → “Smart Bulb is using an Edge Driver” at How To's | Setup Zigbee Binding - SmartThings When you get to the end of that chain, you find a link to generate an OAuth-like token at SmartThings (Samsung account) and then paste it into an Inovelli page that can list device details (ST Device Info Viewer). Don’t lose the token - you’ll need to re-paste it every time you visit the Inovelli page.
