LED Strip driver CW Matter showing wrong statuses

Hi, recently I bought a Zemismart LED Strip driver CW only color. It’s setup on SmartThings and working well, but SmartThings is showing it as a RGBW LED strip. Colors don’t work btw.

I’m using standard Matter driver that Samsung provide and my v3/Aotec hub is on 056.00011 version.

On Apple Home or Home Assistant it shows the device properly, with only CW colors.

The device:

Login here, choose the device, take a screenshot from the whole Summary section and post it here.

It’s probably the wrong profile. Instead of something like light-level-colorTemperature, it’s light-color-level.

- id: "5020/53251"
    deviceLabel: Zemismart LED Light Strip Driver
    vendorId: 0x139C
    productId: 0xD003
    deviceProfileName: light-color-level

Edit: Zemismart is using the same product ID for two different models: with and without RGB (Color Control Cluster). Not cool.

Hi. I did it. Here’s what I’ve seen:


It looks to be using light-color-level

There are two models with the same product ID: one is RGBCW and the other is CW only.

The CSA certificate is for the ZML3 (RGB):

And there’s no certification for your CW model. They just reused the product ID and SmartThings is using that ID to map the profile.

Not really SmartThings’ fault, but they should probe the devices to find out if it supports the Color Control Cluster

Edit: they are currently working on modular profiles for the Matter switch driver. From what I can see, this would solve your issue.

Omg, that’s explain a lot. I hope the new modular profiles fix it. At least it’s an aesthetic detail.

And, yeah, I just opened the driver and motherboard is still RGBW version haha it’s just some software limitation to make the device a CW version

Also, with modular profiles, do you think it will be possible to have features like Power On Behavior that are currently limited to Home Assistant?

WTF. This shouldn’t be allowed and the CSA should be informed, in my opinion.

possible to have features like Power On Behavior

That’s not part of the change to modular profiles. I’ll have a look at it.
