Thanks, I haven’t been able to get it flashed with tuya-cloudcutter either. Finding a post about this lamp on Elektroda, seems to be the previous version of this lamp had a CBU as opposed to what it has now.
I saw your post on the Detailed Guide on How to Flash the New Tuya Beken Chips with OPENKB7231T thread. Please let me know how you go if you try and flash it with Openbeken using the link Ferbulous provided in the response to your post.
