Mm my take is that the camera say it has support for motion which is has. However not over Onvif. So when your app try to enable it i guess it sets your app in some kind of mode however since it’s not really support you end up in a loop or something. I saw in some earlier screenshot you had a manual disable. I guess that option could be good to just avoid confusion. But no biggi.
Just tried the motion snapshot and that works perfect. With my own motion sensor I can then achieve what I want. Also a good thing is that notifications in homey is a bit buggy. Once you looked at them they are gone. At least I don’t know where to find them again. So it’s super simple to press wrong then the image is gone. But now I can just trigger the flow again and get the image back.
Great work and thanks for the fix
