Turn on and off any device connected to a Raspberry Pi (Web Cams, Lights, Fans, Fire Places, Heaters, TV's . . .) via Voice Command. Just touch the screen and say Turn on or Turn off and the name of the device you created when entering the device information on the configuration screen. Link devices together and turn them all on with one word. Link devices on the fly! just say "Turn on bathroom light bedroom light hall light" and all three will come on! Make up whatever combination you need on the fly. Also has a timer option for 30 seconds to 5 minutes. Turn on your bedroom timer and forget about having to turn the light off. Speech commands are not "easy" to translate, but if Google hears you wrong phone will vibrate and show you what Google thought you said and then you can correct either by changing command word or adding new command with that command word. Do this all from your phone, no need to buy extra hardware, besides the Raspberry Pi's of course. IT DOESN'T EVEN REQUIRE PHONE SERVICE! Just a Android device and a network. It really can't get much simpler than this.
