With this Home Automation starterset based on the 433Mhz protocol you can start right away! Just install the RFXcom and connect your power plug, an off you go... Despite the fact that 433Mhz doesn't support two way communication, it's still a popular system because it is quite cheap and there are many nice products on the market. You can extend this set for instance with the following products: wallswitches, dimmers, door/window sensors, sirens, light bulbs and so on.
