Enocean based (Green power batteryless button): use case?

[wb441]

Hello,
I've been experimenting with Zigbee equipment for quite some time now.
I have a couple of Niko Hue buttons which are based on the Enocean technology but have a Zigbee radio in them: PTM-215Z.
The documentation clearly states that binding is not possible.
So, how can I make these buttons do something in the Zigbee network?
