I recently purchased MiBoxer 5 in 1 RGB controller for my RGB led strip and it's fairly terrible. I set it to RGB mode and paired it over HUE bridge and color control precision is awful. Box says that it supports "16 million colors" but i genuinely feel like setting 8 bit color palette. When using RGB color picker it seems to jump over some predefined colors and there's not a lot of them so as a result I'm really struggling to set color that i want.
I'm aware that RGB stripes are not perfect but CRI is most likely not much of an issue for me because i have completely black and white home (literally, everything here is #FFF or #000 and whole house is designed to be colored by light so there's a lot of RGB). I also know it's not led strip issue because MiBoxer controller animates fade between colors and it often briefly fades through exact color that i want, but i can't just set it statically :T
When using it in white mode (cold-warm white) it can display colors that cannot be picked in RGB mode (and tbh they're absolutely terrible as well).
All in all I'm extremely disappointed with this controller and I'm looking for something significantly better, preferably something allowing for callibration to my particular led strip gamut. I was already really disappointed with IKEA bulbs color precision but this controller is another level of terrible lol.
I wondered if that could be the case but it's hard to verify. I only have comparison hue bulb vs ikea tradfri vs this led strip, all cases paired over hue bridge because i don't have ZigBee radio for HA. And while IKEA bulb is not great and colors jump as well it still has much-much better variety than miboxer. I believe tradfri jumping is mostly noticable because ikea bulbs don't animate fade between colors so they just change instantly and thus i can see it's not 100% smooth transition. But it's more than bearable and I don't struggle with color matching all that much there. Unlike that miboxer. Something that scares me away a bit is that all those LED controllers look exactly the same and feel like they're all just the same Chinese OEM rebranded 6000 times lol... Though at leaat one that you linked has 2 buttons instead of one so it may be a bit different design.
