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.
- Etekcity 5 Pack (Try promo code: BHRMTOFF)
- SMAKN 433Mhz Rf Transmitter and Receiver
- Raspberry Pi B+ Ultimate Starter Kit
- 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
- Install Rasbian on Raspberry Pi
- Install Wiring Pi
- Install Apache and PHP on the Raspberry Pi
- Clone web files
- Run: git clone https://github.com/Timl88/rfoutlet.git /var/www/rfoutlet
- Use RFSniffer to find RF codes for your devices
- Run: sudo /var/www/rfoutlet/RFSniffer
- Record all 6 digit codes for on/off for each outlet
- Update toggle.php file with your codes
- Run: sudo nano /var/www/rfoutlet/toggle.php
- Change permission of codesend program so sudo isn’t required:
- Run: sudo chown root.root /var/www/rfoutlet/codesend
- Run: sudo chmod 4755 /var/www/rfoutlet/codesend
- 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.
