Most of the home management and entertainment can be done now...it's just an integration nightmare and a handful of apps for each specific task. Be it security systems, home lights, appliances, energy consumption monitoring, energy generation monitoring, home music and video streaming anywhere in the house, infrared devices, wifi devices, etc...each one requires particular hardware and software to be "integrated" by means of scripts and specialized software. Add in "automatic updates" and the system breaks and needs to "pampered again".
Then throw in the various phones and you end up with about 6 different apps just to control everything.
Need well adopted standards!
