Best RGBW controller for low dimming (under 10%)? Picture attached

Hi,
Super new to home assistant. Just got myself set up with a Raspberry Pi 3 B+ and installed the Hassbian image a few weeks ago. (I found out after purchasing that Hass.io isn’t released for the B+ yet)

Anyway - I took on an LED strip project with RGBWs and purchased a dresden elektronik FLS-PP lp to control it with. It paired with my Osram Lightify Hub instantly and Home Assistant sees it no problem (although I can’t control the white channel through Lightify so I either need a Hue hub or Z-wave stick)

The other problem is I went completely overkill with 24V 5050 RGBW chips and at 100% they are stupid bright. The controller doesn’t seem to recognize anything below 10% and at 10% brightness, the color selection is very limited to about 12-15 different hues.

I have an amplifier on the controller so current capacity of the controller isn’t an issue (and I get the same results with the amp as I do with a short strip directly on the controller).

So my question is out of the hoards of RGBW controllers out there, what one is best, works with HA, is reliable (rebooting it every few days is not acceptable) and can dim down to really low levels?

Must be 24V compatible, I’d prefer something Z-wave but WiFi is acceptable too. I’m not opposed to something expensive if it’s rock solid, I just can’t find anything.

Fibaro?
LEDENET?
MagicHome?
One of the thousands of others?

Thanks and here’s a picture of my project (still in work)

Fibaro RGBW allows to dimm from 1% to 100%.
