It seems so silly to me to not use the ubiquitous "RF" broadcasting stations already in everyone's house, that also includes an "okay" addressing system, a security firewall, high bandwidth communications protocol, and more. Why not focus on software which can use WiFi more securely and with a better focus on local connectivity? I can understand the "ultra low power" needs, but many of these devices are mains powered, and that's not really a concern. But yes, what I do right now for the most part is use z-wave which is connected to a central "hub" which is then connected to the outside world. But IMO that's a hacky-workaround for this problem, not a real solution.
