Hi there! 
I hope you’re doing well. I came across your post about the Osram Smart+ Switch Minis not pairing correctly with SmartThings, and I wanted to offer some suggestions that might help resolve the issue.
It’s frustrating when only one device pairs successfully while the others don’t, especially when they’re supposed to work the same way. This could be due to a few different factors. First, it might be worth checking if the switches are fully charged or if there’s any interference during the pairing process. Sometimes, environmental factors like distance from the hub or other wireless devices can affect pairing.
Another possibility is that the firmware on the switches or the SmartThings hub might need an update. Ensuring everything is up to date can often resolve unexpected issues. You could also try resetting the switches to factory settings and attempting the pairing process again. Sometimes a fresh start can make all the difference!
If you’re still having trouble after trying these steps, I recommend reaching out to Osram’s customer support. They might have specific troubleshooting steps or be aware of any known issues with the current firmware versions.
Let me know if you’d like more detailed guidance on any of these steps. I’m happy to help!
