Hue flashing/blinking light commands on webcore

I’m trying to have some of my hue lights flash or blink upon someone’s arrival (different color depending who’s arriving)
I’m not sure which command to use in webcore, I tried to play with setting but it seems somewhat off
I see emulated flash (color) but I need to set 2 colors which is not something I want (I just one) also the duration and number of flashes are somewhat funky to understand what they really do
Thanks for your inputs

The webCoRE forum is a great place for help with pistons.

Here is a thread i found there that might help give you some ideas:
