I use event Engine, and actually a few other of his apps, and I have found @bptworld to be more than helpful and accommodating, and very responsive. When I started using EE, I flat out told him what I wanted to do. He wrote up a few examples for me and was there to help if I had questions. You have to work with him and give him details, information and sometimes logs so he knows what he is looking for or trying to do. Keep in mind he does it for fun. He doesn't work for hubitat, and he's not doing it to make money.
Near as I can tell, the app you were looking for, lighting effects, isn't a stand alone app, or even a stand out section of event Engine. It is embedded in the triggers, actions etc. I have not used it myself (I looked at it, but it didn't meet my needs) but it is there. I have found with both event Engine and rule machine you are best served to figure or write out what you want and how before working on your rules or cogs. I generally find Event Engine much easier for me to wrap my mind around. Not saying it's perfect, just easier for me.
