I think in the future I may try to get CM15 support going, but they offer very little over a CM11A, and are much more expensive.
Is that future in progress?
The CM11 stopped production some time ago.
The CM12 (Usb CM11) Is currently in 'End of life' so one stocks are sold they too will be no more.
So its down the the CM15,
The is especially true due to the majority of Zwave devices either failing to comply with Australian Standards or failing to find a Distributor. So X10 for us it seems. At least for the moment.
