I get the approach.
Pretty sure (you never know) I did follow the rules.
No errors (..request took xy ms).
No success.
Homey Pro (2026)
Version 13.1.5
However, maybe a Version specific thing.
Scrolling in the feed, I saw [APP][Pro]Flow Converter - Apps - Homey Community Forum - which did it with not trouble.
Can only thank both authors!
Cheers,
Ralf
