At the moment the IKEA Trådfri color bulbs only come as part of a kit with the dimmer. I bought one and I have to say, it’s Trådfri vs Hue Gen 3, but has a deficiency in green/yellow. I’ve tried it with Wink, SmartThings and Hue Bridge. It pairs with all three, but I didn’t bother with looking for a compatible SmartThings Device Handler for color control because I have the Hue Bridge and that’s where I wanted it. Wink does not give you color control at the moment. You can only pair as a generic Zigbee bulb. Apparently, you also get better Hue Bridge control vs Trådfri Gateway currently. I no longer have a Trådfri Gateway with which to test.
The bulb works with Hue because it has the newer firmware the supports Zigbee HA. You can also authorize the remote with the Hue Bridge so it will not be “stolen” by subsequent pairing with the gateway, however this only gives you ON/OFF and dimming capabilities and you cannot cycle through associated Hue Scenes with the Ikea remote in the same way you’re able to toggle through “Moods” when the remote is paired with the IKEA Trådfri Gateway.
The trick with getting the IKEA Trådfri color bulb to pair with a Hue Bridge is, you must first scan for new bulbs in the Hue app, and then put the IKEA color bulb into pairing mode (Power ON & OFF 6 times). It will then appear in the Hue app and you can treat is as you would a Hue color bulb.
If you’re having trouble getting the remote to be accepted by the Hue Bridge, consult the link below. It will show you a basic pairing procedure, which you can in turn use that concept in order to get any Zigbee remote to be accepted by the Hue Bridge and the SmartThings hub. The only difference is you’ll get some feedback from the SmartThings app, but the Hue app will not give acknowledgment that you have paired a non-Hue Zigbee remote, but you will have, and it does work. I have five Lutron Connected Bulb remotes, one IKEA Trådfri remote and one Philips Hue remote paired with my Hue Bridge and various bulbs. They all work, but only the Hue remote is programmable via Hue Labs and third-party apps like iConnect Hue.
