I just did a whole house with Philips Hue lights and the RunLessWire switches. Love the fact that the switches are piezo-powered. The downsides to them are the loud click they make and that you have to learn how to properly press them (with about a 200ms hold) in order to come close to 100% reliability.

They're actually not piezo-powered! That's an EnOcean switch module, it's generating the energy from a coiled wire. Clicking the switch loads up force in a spring mechanism and then releases it to move a magnet through the coil.

ArsTechnica has a look inside a similar module in the Hue Tap.

RunLessWire looks to be selling two variants of them, one with the same 2.4 GHz module as above for use with Hue, and another version for on/off circuit control, which would be 902 MHz EnOcean in the US.

My water filter infuriates me to no end with this. Maybe if the switch were polled every 50ms I wouldn't notice it, but 200ms is so long for my otherwise patient composure that I prefer to drink the water from the tap.
