Thought I’d share my experience so people don’t make the mistakes I have. Ikea recently announced that their TRÅDFRI bulb were compatible with Philips Hue. I went to ikea to grab some bulbs. Got home and tried to connect them only to find they need a firmware update to make the compatible. To do the firmware update you need a TRÅDFRI gateway. Another trip to IKEA to pick up a gateway. Get home, connect it all up to find you can’t connect a bulb unless you first connect a switch or motion sensor. So I’m going to have to go back again to get a switch. In short, if you want to use ikeas bulbs with Hue either wait until someone has confirmed that they are stocking bulbs with the latest firmware. Or make sure you get a gateway and switch as well as bulbs just to update the firmware.
