DIYer Tim Leland decided to build his own using a Raspberry Pi and some cheap RF power outlets.
The project controls your power outlets over RF and a Wi-Fi connection powered by the Pi.
Once it’s set up, you get a web interface to control your power outlets from.
Head over to Leland’s site for the guide and necessary software.
