High power LED controller

I am looking to control (dim only) about 200ft of 2835 led strip (understand will want to inject power at several points). What I am here to ask about is the controller to handle it.

By my calc this is 3360 LEDs, 24v, 0.2w/led=28 amp

Looking for suggestions on cheapest controller for this that will work in hubitat. 1 channel is obviously best (or multi channel is fine as long as 1 channel can handle 28amp) is this way outside of normal? Or should I be looking to group multiple controllers together in hubitat, and split my run up into 5? segments or what?

That is pretty high. The main two I use:
GLEDOPTO RGBW Controller
Zooz ZEN31 RGBW Controller

Both have a 6A max per channel, with a lower combined value of 15A for the GLEDOPTO and only 10A for the Zooz.

Yeah I have both of those for other stuff. Maybe I am overthinking this. There are kits on amazon with 3000 leds somehow pulling like 24w.... they must just be under powering them like crazy or something.

If you are wanting to only use one controller to run this, you should look for an LED signal amplifier. Here is one on Amazon.

I haven't used any of them, but this is a situation I would give them a try, or just add more controllers, and operate them from a group.

RGBGenie has a single channel that can do 8A 12-36V, still not really in the neighborhood of what you're talking about. I'm thinking using a normal single channel LED controller to toggle a relay is the best bet here, probably need a 40A DC rated relay, automotive is probably the cheapest source. You won't have pwm (dimming) but it'll work.
