Matter Scene problem

Hello. I have a Sonoff Ultra controller at home, and I can add my Zemismart ZML3 RGBCW LED controller as a Matter controller. This allows me to control the light intensity, color, and dimmer of the devices. However, I cannot control this ZML3 controller (and actually all my Matter controllers) from the scene. What could be the reason for this? When I add these devices to my Aqara M3 hub, they can be controlled from the scene.

I’d like to first confirm a few details with you to make sure I fully understand your issue.

  1. The device with the problem, Zemismart ZML3 RGBCW LED, is itself a Matter over Wi-Fi device (I’ve seen the official product link: Zemismart Matter Over WiFi Led Strip Light Controller RGBCW Smart Led Driver Support Smartthings Alexa Google Home App Control).
  2. You are using the Matter Hub feature of the ZBBridge-U gateway to add the ZML3 device to the ZBBridge-U via the eWeLink app, and you can normally control it in the eWeLink app (on/off, brightness adjustment, color control, etc.).
  3. You are unable to select the ZML3 device (or in fact any Matter devices added under the ZBBridge-U gateway) as a trigger or an action in eWeLink app scenes.

Regarding the “cannot control” issue, you could also describe it in more detail.


Additionally, please note that when using Matter features, you must ensure that the ZBBridge-U and the Matter device (ZML3) are on the same local area network (LAN). For example:

  1. ZBU (192.168.50.3) vs ZML3 (192.168.50.47) — they are on the same LAN.
  2. ZBU (192.168.1.3) vs ZML3 (192.168.50.47) — they are not on the same LAN.
