433MHz Smart Home Controller with Sensorflare and a RaspberryPi


In this instructable we show how to use a 433 Mhz transmitter to control your home’s RF devices though Sensorflare using a RaspberryPi.

Components Required :

Step 1: Setup Sensorflare to communicate with you RaspberryPi

First you need to connect to Sensorflare and visit the Connected Accounts page to enable communication between Sensorflare and your Raspberry Pi.

Click the “Add new account” button and select Raspberry Pi 433MHz RF option.433MHz Smart Home Controller with Sensorflare and a RaspberryPi

Step 2: Securing your connection to Sensorflare

At this point you will need to set a password so that the communication between your Raspberry Pi and Sensorflare is protected.

Keep this password in mind as you will need to set it later on your Raspberry Pi.

Step 3: Copying the property file

After you have successfully set the password the contents of the property file to be added to your Raspberry Pi are available. Copy the contents to a local file and replace ‘****’ with the password you entered in the previous step.

Step 4: Connecting the RF transmitter

First we need to connect the RF transmitter to our Raspberry Pi as displayed in the image above.433MHz Smart Home Controller with Sensorflare and a RaspberryPi schematic

Step 5: Installing the Software on the Raspberry PI

The next step is to install the libraries that are needed send RF commands using the Raspberry Pi itself.

  1. We need to install WiringPi following the instructions available here.The commands usually needed are:
    sudo apt-get update
    sudo apt-get upgrade
    sudo apt-get install git-core
    git clone git://git.drogon.net/wiringPi
    cd wiringPi
    git pull origin
    cd wiringPi
    ./build
  2. Next we need to install codesend. Detailed instructions and information is available here. The commands usually needed are:
    git clone git://github.com/ninjablocks/433Utils.git
    cd 433Kit/RPi_utils
    make
