Harmony Hub + ST relationship - help!

Just fired up my new Harmony Hub and I have it setup as a Thing in ST. In the Harmony app my devices are functioning. Now I just want to create a routine that when pressed does this:

Turns on the basement HT lights to 40%
Turns on projector, receiver, and Apple TV
Turns off HT lights after 120 seconds.

I’m confused on how to bring the Hub into the equation here. Thank you!

Talk to @arielgon we were just talking about this in this thread.
No matter what I do I can't get Echo, Harmony hub and ST to cooperate
He just finished doing this.
