How do I add my lightbulbs to ST. Not showing up when scanning

Try using the device code in the linked post. Don’t worry about it saying it’s for the Kudled bulb. They’re identical to Hue bulbs. You probably just need the endpointId hardcoded and this will do that. You will need to follow the FAQ that @JDRoberts posted for you in the other thread to install this code in the IDE as a new Device Handler, then apply it to your bulbs.

If you can reset them (Hue bulbs don’t reset using the on/off cycling method like the Osram bulbs) and pair them one at a time; it could help you get a better join and not need the custom device handler.
