Wirelessly control power outlets from your phone using Raspberry Pi #piday #raspberrypi @Raspberry_Pi
HackADay posted this great project from Tim Leland. Check out more info here.
Have you ever wanted to wirelessly control power outlets from your phone? You could buy a Belkin WeMo Switch for over $40 for 1 outlet or build your own with 5 outlets for under $35 if you already own a Raspberry Pi. Hopefully this post will guide you in the right direction.
Hardware Needed:
Etekcity 5 Pack (Try promo code: BHRMTOFF)
SMAKN 433Mhz Rf Transmitter and Receiver
Raspberry Pi B+ Ultimate Starter Kit
Steps:
Connect wires to Rf transmitter and receiver chips. If you use different gpio pins the programs CodeSend and RFSniffer will not work. If you would like to use different pins check out Ninjablocks 433Utils
Browse to Raspberry Pi ip address ‘http:///rfoutlet/ App demo
Now you should be able to power on/off your outlets from a web browser. If you would like more range you can add an antenna to the transmitter chip. I cut a 12 inch wire from a cat 5 cable and it worked great.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
Have an amazing project to share? The Electronics Show and Tell is every Wednesday at 7pm ET! To join, head over to YouTube and check out the show’s live chat – we’ll post the link there.
This is interesting. I wonder if there are any dual outlet devices out there that can both control on/off and tell me how much power I am using. That would be a neat project to not only turn all your outlets on and off remotely but also see how much each outlet is using.
