Lifx matter bulb not showing up as color changing

Devices & Integrations
1

Can’t get these bulbs (2 of them) to show as color changing in st. Only dimmable and color temp.

Connected direct vía matter, firmware updated to latest, no errors showing, it works and connects perfectly, just no color support.

Have gone directly through st, as well as generated a new code vía lifx app and done it that way. Same issue both ways.

Any tips?

I should also mention, I have matter color bulbs from other manufacturers that work no issue. All use that same matter switch driver

It’s because the fingerprint points to light-level-colorTemperature and not light-color-level.

  - id: "5155/163"
    deviceLabel: LIFX Supercolor (A19)
    vendorId: 0x1423
    productId: 0x00A3
    deviceProfileName: light-level-colorTemperature

Don’t know if it’s a mistake.

Edit: Checked the CSA page. The LIFX Supercolor A19 (VID 0x1423 / PID 0x00A3) is officially certified on the CSA site as Extended Color Light (0x010D).

This means it should support full color (Hue/Saturation) + color temperature. However, the Matter Switch driver is matching the fingerprint 5155/163 to the light-level-colorTemperature profile (0x010C - Color Temperature Light only). That’s why full color controls are missing.

Looks like a fingerprint mapping issue to me.

Any solution?

I can also submit an issue on GH. Edit: done.

In the meantime, I can create a modified version of the driver, so you can test it with your device. Not at the computer at the moment - check back tomorrow.

Cheers mate

  • Switch the driver from within the SmartThings app: three dots → driver → Select different driver

Bulb works perfectly now! Light strip still has the same issue though.

Half way there! Any change you can take a look at the strip? Thanks again

You haven’t mentioned a light strip before!

Need a screenshot from the device’s information page for the vendor and product ID and I’ll modify the driver again - but probably tomorrow.

Holy crap. Not sure how I missed that. Talking in to many forums I guess. Sorry!

You can also give Matter Playground a try, it does not use the fingerprints for smart bulbs / strips and dynamically profiles them based on what they support.

It also unlocks many features, although LIFX last time I checked used an old Matter version so YMMV.

@mocelet Check this out. :grinning_face_with_smiling_eyes:

Going to create an issue later today.

I actually thought they already had dynamic profiling and fingerprints were not that important now but looks like for that particular case they don’t?

14

That’s what I thought as well …

The whole dynamic profiling / modular profiles system is still unfinished. And at one point they should figure out how to do dynamic preferences as well.

BTW: there was a time when it was considered best practice to start these comments with TODO: because the IDEs would handle them differently. They would nag you to actually do something eventually.

Issue.

Changed the profile for your light strip in the current version:

───────────────────────────────────────────────────
 Driver Id    0b00bd83-be2c-4f1a-ba8f-2dcd6e123868 
 Name         Matter Switch (LIFX TEST)            
 Package Key  matter-switch-lifx-test              
 Version      2026-06-13T11:39:31.372743848        
───────────────────────────────────────────────────

Important note: check back here at least once a week, because you shouldn’t use this driver forever. As soon as the issue is fixed in the official driver, you should switch back to it.

Confirmed. Colors working on the strip now. Thanks for the help on this. I’ll continue to check in for updates.

Cheers all.

Thank you for the report.

The team is currently working on correcting this issue and is also in communication with LIFX to ensure it is properly addressed.

We’ll let you know once the fix has been released to production so you can use the SmartThings driver with the correct functionality.

Thank you for your patience.

Hi,

The team has already prepared a fix for this issue, and it will be included in an upcoming driver release.

Please keep an eye on the driver version to confirm that you’ve received the update. Once your driver has been updated, let us know if the issue has been resolved.

Thank you.
