Using IKEA TRÅDFRI dimmer on Philips Hue

How to pair the IKEA TRÅDFRI dimmer with your existing Philips Hue system to get a cheap remote control of your bulbs.
If you have the IKEA TRÅDFRI remote or the IKEA TRÅDFRI motion sensor instead it's exactly the same recipe.

You /may/ need to update your IKEA remote if it's using an old firmware. For that you'll need an IKEA gateway - which is not covered in this video as it is standard IKEA procedure.

Compared to Hue control units it has both advantages and disadvantages.
It's cheap
It's basic so once setup it's easy to use for everybody
It doesn't take up resources on your bridge as it's just a ZigBee node on your system which the bridge is unaware of
It'll control your bulbs even if your Hue Bridge is turned off
It's not configurable from the bridge/hue or other app so no fancy things
Since it's talking directly to the bulbs (through the ZigBee network) it can take up to ½ a minute or so for the bridge to be aware of the bulb's new status

Not applicable for this Trådfri dimmer as it's only on/off and dimming but applicable for the Trådfri remote:
For the moment it seems that adjusting color temperatures and colors are only supported for IKEA bulbs - also IKEA bulbs on the Hue system. Lets hope for an update to the remote in the future.
