You need to find a device handler for the lights. Given that they are Zigbee 3.0, you might be able to use one of the built-in Zigbee Light device handlers.
You’ll need to do this in the IDE:
- Log into the IDE at https://graph.api.smartthings.com
- Go to My Devices.
- In the list, you should see the lights that you just added. Click on the name of the device to access its properties.
- Scroll to the bottom of the page and click on “Edit”.
- Given that they seem to only be tuneable white, I’d start with the “Zigbee
White Color Temperature RGBW Bulb” device type.
- Click on “Update”.
Now, in your mobile app, log out and log back in (you might be able to do a simple refresh in the “My Home” tab, but a log in/log out refreshes better imho).
Test the light and see if it works. If it doesn’t, try the “ZLL
White Color Temperature RGBW Bulb” device type. That should at least get you basic control of the lights. If all else fails, you can try to work with one of the awesome devs we have here in the community to hammer out a custom device type handler.
EDIT: Just saw where you posted the controller type.
