I have a philips hue system and want to be able to operate it via the app as well as via the remote control, these should complement each other, not get in the way. After help from Coolblue, transferred to KAKU because I couldn't figure it out with this manual:

At step 2.B it says: channel 1,2,3,4,5 blink once, this did not happen with me. So instead you walk up to your hue lamp, hold your ZYCT against the hue lamp and press the I button. Hold this until the lamp starts flashing, then it goes from weak to bright (takes about 10 to 12 seconds in total). If you want to link more lamps under the same "led group", keep that group selected and do the above again. Now this remote works perfectly with the hue app! (note: switching off the lamp(s) is 2x short 0, switching on is only 1xI).
