It can control lights, plus audio and video equipment, and even hook up to a digital lock for automated door locking—and it doesn’t cost an arm and a leg and maybe another leg. It’s Mi Casa Verde’s powerhouse little Vera system, and it works with wired or wireless web cams as well as Z-Wave compatible light switches and dimmers, outlets, thermostats and motion sensors. It can also be controlled by iPhone, iPod touch or Android phone—so you can stay in touch with your home.
