Mi Light Wireless 2.4G RF RGB + White/Warm White Controller Kit, 4 x Controllers and 4-Zone Remote, Wi-Fi Bridge Compatible, 4CH Multicolor RGBW/RGBWW LED Strip Light Controller

I'm using these to dim some white only lights, and so far so good. Please note the PCM is active on the negative side and the positive is just a pass through. Each of the units controls a separate zone. You can select which zone you want to control via the remote.

Once you get the hang of the remote, it is great. There is no true bright white, but close. I had used the same lights with a different controller and got the bright white, so I know it was not the lights. The ability to control multiple strings is great. Once you get what you want, walk away from the controller. It is very sensitive and your warm hands could totally mess it up.

It does what you expect. It’s easy to connect and pairing multiple controllers with one remote makes creating a large set up very easy (1 had 18 controllers with 1 remote). The only con is the remote is very sensitive so you can’t just hold the remote on your hand otherwise you keep activating functions or changing colors accidentally. I prefer remotes with actual buttons you press.

Worked great and easy to install. Be advised that if you connect this RGBW controller to only RGB there are certain modes in which the light goes dark because it is outputting on the W pin which is not connected. You could connect this to another color but this didn’t meet my needs. Seller promptly replaced with an RGB unit. Great service!

Ultimately they were real cool. Worked great separating the zones . But it’s been maybe 3 months under minimum use and 2 out of 4 don’t work anymore.
