Wireless Power Outlets RF from Raspberry Pi

Thanks LifeHacker and HackADay for featuring my post. If anyone has questions please leave a comment below and I’ll be happy to help!

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.

Steps:

1. 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

1. 1. Run: git clone https://github.com/Timl88/rfoutlet.git /var/www/rfoutlet
2. Use RFSniffer to find RF codes for your devices
   1. Run: sudo /var/www/rfoutlet/RFSniffer
   2. Record all 6 digit codes for on/off for each outlet
   3. Update toggle.php file with your codes
      1. Run: sudo nano /var/www/rfoutlet/toggle.php
3. Change permission of codesend program so sudo isn’t required:
   1. Run: sudo chown root.root /var/www/rfoutlet/codesend
   2. Run: sudo chmod 4755 /var/www/rfoutlet/codesend
