Residential automatization should not be complicated. should be easy as plugging a bulb or a fan. With the BT modules, you can control each thing separately, without any wires or complex setup. Just connect the module, open the app on your smartphone and control everything. (both 110 and 220V are supported).
When leaving home, just press the "Turn all off" button, and go ahead. When going in vacation, just press the "Travel mode" button and let your lamps imitate your on/off patterns and don't care about thiefs, just enjoy the trip!
