Got myself a wired selfie stick now and it works like charm. Video capture on and off works perfectly with Open camera even. I guess you can do much more if you learn the “Morse” codes of the button to zoom in and out and that.
Bluetooth did not work after all which is a bit strange because I had a connection but nothing happened when I pressed the button. Since Bluetooth selfie sticks address the exact same button I have no idea why this way is not functioning.
