While useful, the fact that it only allows one action for each button is not ideal. That is, each button can be a scene or a state, but not cycle through and you will need another button for off state. The other Philips switch is more practical, unless you need a battery free alternative.
UPDATE: You can modified the operation of the device using Philips developer kit, API commands and JSON.... if that made sense to you, then you will find altering the commands so that a single button pressed once turns on, pressed again turns off - this way you can have this remote control multiple rooms, even one button for on/off the entire setup.
If not, then you will either have to stick with the basic function or look at alternative app to control your Philips Hue setup that allows customised buttons - you will have to pay for this.
Change the way you control light at home with the Philips Hue Tap Switch. Remotely recall your four favourite Philips Hue light scenes at the press of a button. Select from your own scenes, scenes created by Philips, or program a button to switch all lights on/off. Requiring the Philips Hue Bridge (sold separately) for the full Hue experience, this switch does not need batteries. It uses kinetic energy and is powered by your touch. Mount the Hue Tap anywhere with the included mounting plate, or detach it and carry it with you as you move through your home. Add up to 12 other Hue accessories (sold separately) such as the Hue Dimmer Switch or Hue Motion Sensor. Control by voice with Amazon Alexa, Apple Home Kit and Google Assistant. Connect it with your Nest or Samsung SmartThings system. This box includes a Hue Tap with wall plate and two-year warranty.
