Ok, soffit first. That strip you linked is warm white only. Since the soffit is pretty close, here's my setup:

Lights: 2 x https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
Power: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
and Fibaro of course: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1

Then various connectors, right angle connectors for corners, etc... For the setup, I have my power supply in the soffit. The Fibaro connected to it, then a red, green, and blue wire out of it that is connected to both strips. Then the 24v lead from each strip is connected directly to the power supply. The power doesn't pass through the Fibaro, it just gets its own power and sends out the signal levels for the 3 colors. In my case, this is in one corner of the room, so one strip fed each direction and they meet up at the opposite corner.


Now, for the columns, what I was talking about was the idea of putting the real power at the start of each column. So you'd have the Fibaro wherever you need it, running the RBG wires to the top of each column. Then, before it connects to the strip in a given column, you'd put an inline amplifier (i.e. a baby power supply). It would get the power either from an outlet, or a 24v loop around the soffit, then be combined with the 3 signal wires from the fibaro. In other words, the Fibaro and the actual light strips would not be using the same power supply. I wish I could draw up a sketch for you, but I suck at that, and I'm buried at work right now, only had a couple minutes to breathe. Using an inline amplifier means having to power each one, but takes away the worry of voltage drop.

Using the strips I went with as a guide (Supernight 24v RGB 10m reels), they hit at 144 watts per 10 meters. You'd be looking just shy of 20 meters, so assume 288 watt load. I'd suggest a power supply with enough overhead to prevent the fan from coming on, or find a really quiet supply (can get pricey). Fanless at that power would get pretty hot, I'd be wary of having that in a soffit. With that approach, you'd have 2 10 meter strips that would both connect to the power supply and contoller, meaning each run is only 10 meters, so you shouldn't see any light drops. I'd suggest a 350 watt supply. I went with this 360 watt model https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1 which works well. Unless I crank the lights (my normal programmed level is about 15% bright), the fan never comes on.

The columns are a bit trickier as your total light distance is getting up there. I'm not sure you'd be able to use the same controller that would be running the soffit lights or need a second one. Using a second Fibaro, you could power it with a small supply, run 18 or 22 gauge wire to the columns and put in-line amplifiers to power each column. The challenge there is getting juice to all 7 columns from two outlets, or running a lot of romex around the soffit. Still, that approach would give you a single controller for all 7 columns. Alternatively, you could get a beefy power supply, and run a single thicker gauge power wire around the room. In other words, one small power supply to power the Fibaro and send the control signals around the room, then a second heavy duty supply to send a 24v wire around the room to each column. Then at the column head, you attach the control wires from the Fibaro and the Power wire from the big source. I'll have to defer to others on here to the code/safety aspects of that. You'd use something like this to run the control signals: https://www.amazon.com/accexpert%C2%...s=rgb+led+wire then a higher gauge from the big supply. Since it's only one wire, just buy a reel of whatever gauge you want to go with.

Ok,
I appreciate you trying to spell it out.
I think I understand somewhat better.

You're sayingfor the soffit whereas an RGB strip needs 4 wires (Red green blue and black), you're saying you used 3 wires, red green and blue in small gauge, and for the 4th wire, you're using a larger gauge black wire which is actually supplying most of the power, and that wire goes from strip terminal, directly to the black + terminal on the power supply? So, a red and black go from the power supply to the fibaro, and you're connecting a black from the strip back to the SAME black terminal on the power supply where the first black (of the red and black) are connected?

Correct. This is actually the intended wiring for the Fibaro.

http://manuals.fibaro.com/rgbw/

Look at the RGBW strip wiring diagram (in our case, RGB so ignore the W wire as it's not in play). The feed from the power supply is what goes to the Black wire on the strip.

Remember, no matter where you go... You're not where you were anymore.
