Device discovery problem in Zigbee2mqtt

Wouldn’t you be more comfortable using an external tool by exporting your database to at least get the uuid?

You can check Pierre-Gilles’ post:

For my part I almost only use that!!

Turn off Gladys, download the database to your PC/Mac and view it.
If you made a backup beforehand, you can delete it in TablePlus then re-import your database (be careful with permissions — I have to open permissions to everyone then put them back afterward)
