node-raspi-rcswitch-api

RESTful API for the node-rcswitch binding based on Node.js/restify. Allows controlling of 433Mhz RC remote controlled power sockets with the raspberry-pi using HTTP Protocol. There is a german post on my blog describing the hardware requirements and schematics.

Requirements

• To use node-rcswitch, WiringPi must be installed in order to compile.
• Tthe data and power Pins of the transmitter must be connected to the Raspberry Pi.

Installation

$ npm install raspi-rcswitch-api

Configuration

• transmitter_pin defines the GIPO pin on which the transmitter is connected to the Raspberry Pi. Note the number of the WiringPi data Pin. (see http://wiringpi.com/pins/)
• retries number of times the signal is send (optional)

Usage

Starting

$ npm start

> [email protected] start /home/pi/node-raspi-rcswitch-api
> node daemon.js start

raspi-rcswitch-api Server started. PID: 9082
raspi-rcswitch-api listening at port 3000

The server is running as deamon using daemonize2 by default. As alternative you can start with

$ node server.js

Stopping

$ npm stop

Direct device access

http://host:port/api/v1/switch/systemCode/unitCode/state

• systemCode five character long binary system code identifying the rc switch system.
• unitCode integer number between 1 and 4 identifying the power socket number in the system.
• state can be either on or off for the target state of the power socket.

For example a GET call to http://host:port/api/v1/switch/10101/2/on will switch on the second power socket of the system 10101.

Mapped device access

You can specify named devices in the device_config.json file to gain quick access to them.

The following example provides access the power socket with the system code 01001 and the unit code 1 under the name Living_Room_Ambient_Light.

{
  "Living_Room_Ambient_Light": {
    "systemCode": "01001",
    "unitCode": 1
  }
}

Now you can quickly access the power plug using http://host:port/api/v1/switch/Living_Room_Ambient_Light/state. For the state and the config values the same restrictions as mentioned in 'Direct device access' section apply.
