I have the same lamp and only realised yesterday after a while that I can also control it via the remote control. However, the dimmer levels are somewhat coarse, i.e. you can dim it less well to the desired brightness. Of course, the colour cannot be selected via remote control.

I can't find a switch or any touch switches. I only use the lamp without any bridges or other Hue devices.
But I think there are certainly switches to buy and link in the system.
