You’ve clearly decided I’m ‘wrong’ without looking to read what I was responding to.
Which was...
Still can't believe someone hasn't made a receiver/shutter release system, I would think that would be pretty useful. But maybe its too niche.As I read it the OP would like an all in one solution to fire the camera and the lights ‘at the same time’, I was explaining the timing problem, which you then also explained.
You’re clearly reading something different.

Oh. i see what you are saying now.
I'm approaching it from the POV that a press of one button to set the shutter release > flash fire process in motion is in practice, "at the same time"
You are approaching it from the POV that there is some tiny fraction of a second delay between shutter release signal being sent and the flash firing, so it is not technically, "at the same time"
I'm still on my first cup of coffee, but I don't think that any amount of engineering would be able to overcome the minuscule delay, or provide any benefit to the user.
