@petro but thats the just the thing, something changed caused what was working 2 weeks ago setting it through MQTT like you showed me; isnt working now.
So now I CAN set partials through the service call. Heres a working flow where I can set the dimmer bar to either red fast blink or green pulse. I had to add the 500ms triggers between each one or else sometimes not all 4 would get set. For example, it would change to pulse, but still be red instead of green.

I used this page, which I just found out about and really helps with parameters.
