Hello Dave,
We are busy getting Lua Drivers ready for all SmartThings users. We are using this file to communicate fingerprints that belong to DTHs that will be Migrated to Lua Drivers. Please note, we are migrating Hub Firmware Beta users to our Beta Channel, not the default join channel.
I have reported your migration issues to the development team, thanks again for your communication. I will follow up as soon as we know more.
