For a bit more detail, SmartThings isn't required in most cases, but adds additional capabilities. Harmony, while quite powerful, has focused so heavily on their activity based approach that they've limited some of the capabilities that would exist if they'd just allow straight macro commands. So yes, you could have Harmony power everything up after getting a command from a smart speaker (I'm not sure if Harmony knows what to do with a Fibaro led controller). It's the additional automations where something like SmartThings comes into play. For example, SmartThings could have triggers that respond differently at different times of day. Plus SmartThings using webcore can trigger events based on receiving a URL command.
So as an example, here's how my automation works (can't remember if I listed it out in this thread or not).
"Alexa, turn on Cinema mode"
This calls an action in Harmony which turns on a virtual switch in SmartThings in addition to Harmony remote commands
-Theater Drapes close (SmartThings)
-LED lights set to specific color and level (SmartThings)
-Theater lights turn on to specific level (SmartThings)
-AV Equipment powers up (Harmony)
-AV set to correct input (Harmony)
-Screen drops (Harmony)
Without SmartThings, I don't think I could set specific dim levels for the lights, and pretty sure I couldn't select the LED color setting (especially when I want it different based on time of day or the like).
Additional automation with Kodi/CinemaVision using SmartThings (the webcore app can respond to URL triggers which CinemaVision can send)
Start movie sequence
-Lights set to 25% (it's actually pretty bright in my case)
-LEDs set to red and 20% brightness
-Trivia slides begin (I have several versions running from just a couple minutes to 30 minutes if I want to have it running when people arrive and are getting situated)
-Lights dim to 15%
-LEDs dim to 10% and switch to blue
-Theater intro runs (just for fun. I actually use an old one from Showcase Cinemas in Boston from the early 2000s)
-Trailers run (again different modes ranging from 1 to 3 trailers)
-All lights turn off
-THX Intro (just because it's still the best, but I do have others for Atmos and such, I just like the original)
-Additional actions, if I click pause, lights automatically come on to 5% to make it easy to move around, and go back off when I resume.
-End of movie, lights come back up to 15%, LEDs back on and a purple color.
