OK, this would sound like all the usual wishful thinking nonsense you see in Kickstarter campaign’s except for one thing: the source of the comments. Official zwave alliance comments to a reputable news source, FastCompany.
They’re saying that the new security 2 framework for zwave is there in part to allow an eventual zwave/HomeKit hub for use by professional installers.
Also note the really interesting comments from Fibaro about how the Z wave and homekit versions of their sensors vary technically.
Additional comments from Yianni at Philips regarding zigbee.
