Before I get started..... I am an electrical engineer with a lot of circuit design experience.

So I just bought a couple of the Chinese LED lights (55x3W) wifi enabled. The real pain on these things is the configuration. If you have more than one you have to turn off your phone wifi.... change the configuration.... turn wifi back on and restart the app. It looks like the wifi board inside simply puts out 0-10V to the LED drivers. I don't know how much current the LED drivers pull but has anyone tried running GND and the 3x 0-10V signals from one wifi module to the other light? That way they would both be controlled the same?

I have seen mods to use these with the Apex controller but not to chain 2x of them together.

Is it 0-10V or PWM?

In either case there should be no problem just paralleling the control signals to multiple drivers. If there are issues, a buffer op amp (for 0-10V) or a Schmit trigger buffer (PWM) will solve it
