Cheap Home Automation

One of the most difficult aspects about smart homes, is that we’re trying to retrofit our old homes to become smart homes. As such each light switch and outlet has to have it’s own controller, it’s own switches etc. This makes setup time consuming, and requires more expensive equipment. Life would be easier if we could have one set of centralized controls.

RF Remote Switches

That’s kind of what iam is going for with his $10 smart home project. By using a 4-way remote control unit, he is able to centralize his controller (a Raspberry Pi), and use simple RF remote controls to control devices around the house. The great thing about RF switches is, although maybe not as secure, you don’t have to worry about pairing, or connecting. You buy them and they work.

Amazon has a wide array of products you can choose from for this kind of application. A lot of them operate only at 12V though, for use with garage doors, so be sure to select one appropriate for your application. 110V are available, and come in single and multi-channel variants. You could possibly even avoid the dodgy wiring by picking something like the Etekcity Wireless Remote Control Switches.

Connect the remote to your centralized hub and you can have your smart home up and running in no time at all.
