I have another simpler idea.
I read the manual you sent. In Photon, do in the fixtures list. Then find the LIXADA manufacturer in the list, swipe “LED Mini Mooving Head Light” and select the duplication icon.
The editor will open and you can edit the fixture properties.
Then edit the “strobe fixture”, touch “+ OPEN/CLOSED” to add the shutter open/closed values.
Set OPEN : 134
Set CLOSED : 0
Then save the device, you will find it in the “My Custom Devices” manufacturer.
Then you have to add in your DMX mapping to address it.
Tell me if you understood what I said and if my solution works. It’s not very simple = S
