Node app to controll 433mhz switches connected to a raspberry pi

switch

Setup

In order to controll 433mhz transmitters connected to your Raspberry pi, switch uses rcswitch-pi and wiringpi.

You can $ rake bootstrap to install all necessary dependencies automatically, alternativly you can install the node dependencies and submodules manually:

$ sudo npm install
$ git submodule init && git submodule update

Afterwards follow the instructions on how to build wiringPi and rcswitch-pi via the links above.

Hardware

I'm using a 433Mhz transmitter like this. There are several good tutorials online on how to connect the transmitter to a Raspberry pi. I also will add a sketch for the connections to this readme soon.

Controlling the switches

To control a switch you need to pass the id, unit and state of the switch in the request body. An example POST request JSON body to controll a switch looks like this:

{
  "id" : "10110",
  "unit" : "1",
  "on" : true
}

At the moment there is no authentification, so anyone in your network could control the app. This could easily be changed by adding Passport or something similar.
