Describe the issue

Responding here to my remark in the other issue to support type 8 blinds (TDBU). Happy to help you out with some testing. Can't disconnect a shade from regular operation for long without being able to switchthem back to normal operation though, I will get in trouble with the missus. But if I can help you out providing info that's sniffable, or if there's a low-impact way of switching control back and forth I'd be happy to help you out. No expectations in result and time. I have to share my time so here and there as well. Let me know if I can help.
