Zigbee/Z-Wave replacements for LED downlight drivers

Hi Aussies (and Kiwis),
I have a bunch of these LED downlights that I'd love to re-use:

Is it possible to buy a Zigbee or Z-Wave controller that replaces the existing LED driver? If so, could anyone recommend one? I'd like it to be dimmable like the existing driver.

A close up of the existing driver:

Thanks in advance!

The trouble is the constant current driver. I recently looked for one, and all the Zigbee and Zwave drivers I could find are not constant current.

Oh man, that's a curveball. I just assumed everything was constant current. :-/
