I snagged one of the Philips Hue Smart Button V3 (model 605774).
Oddly enough the List of Compatible Devices Amazon link for Philips Hue Smart Button 046677553715 takes you to it.
It will pair and auto select the Philips Dimmer Button Controller V2 driver, also manually tested the Hue Smart Button driver.
It semi-works, but it triggers 3 presses for each press.
