Ive gotten a lot of e-mails in the past about controlling lights, plugged-in utilities, etc. with my voicecommand software on the Raspberry Pi and I decided to make a quick easy guide.
Why would you want to do this?
This is an easy question to answer. I walk into a room and I say Pi . . . Let there be light and behold the lights turn on. Or for those with less dramatic flair, just saying lights and having the lights turn on.
Having voice controlled lights in your house just seems convenient.
How can I do this?
Its easy actually.

Once you have the image on your Raspberry Pi, buy some RF 433 MHz light switches or sockets like these:
Ive created an image for the RPi that already has everything you need on it. This means its easier than ever to control electronics with your voice.
You can download it at:https://mega.co.nz/#!MM8W1JxR!4PlZ_1-dumasDUCYRI4LuiBwEJgtqhfoin0R8ls90NQ
Once you have the image on your Raspberry Pi, buy some RF 433 MHz light switches or sockets like these:
Etekcity ZAP 5LX Auto-Programmable Function Wireless Remote Control Outlet Light Switch with 2 Remotes, 5-Pack Outlet
You can plug those into an outlet and plug anything (including a light) into them.
Next you need a 433 MHz transmitter and receiver for the RPi. You can get those here:
433Mhz RF transmitter and receiver kit for your Experiment
Then you can wire them up to the pi using the GPIO and use pilight to control them. You wire them in as below:
The smaller unit is plugged into voltage, ground, and pin 17 while the larger board is plugged into voltage, ground, and pin 18.
Once your transmitter and receiver are wired up, simply point the remote at the receiver, run pilight-debug, and press the button on the remote you want to learn. Now you can copy that string and use pilight-send to send it.
Example:
sudo killall pilight-daemon or sudo service pilight stop
sudo pilight-debug
Then CTRL+C when you see a RF string. Mine looks something like this:
172 688 172 688 172 516 172 688 172 688 516 172 172 688 516 172 172 688 172 688 172 688 516 172 172 688 516 172 516 172 516 172 172 688 172 688 172 688 172 688 516 172 516 172 172 688 172 688 172 5814
**Note** Sometimes I have trouble escaping out of pilight-debug. When that happens I kill it (kill -9) from a different terminal
Now I can turn that light on.
First restart the pilight daemon:
sudo pilight-daemon or sudo service pilight start
Now send the command:
sudo pilight-send -p raw -c "172 688 172 688 172 516 172 688 172 688 516 172 172 688 516 172 172 688 172 688 172 688 516 172 172 688 516 172 516 172 516 172 172 688 172 688 172 688 172 688 516 172 516 172 172 688 172 688 172 5814"
but with your own string. Do this for the on and off settings for as many lights as you want.
Now I can add that command in a script and use voicecommand to run it when it hears the right command!
You can do this with voicecommand -e
You can plug those into an outlet and plug anything (including a light) into them.
