ESP8266-IoTJS

Package for control ESP8266-EVB (with loaded ESP8266 olimex IoT firmware ) over WebSocket. Npm package link

Use at your own risk, it is Beta 0.0.1

Work properly with only one board connected to host at the time

only work with

• Relay
• Button
• MOD-TC-MK2-31855 - temperature sensor (K-TYPE THERMOCOUPLE)
• more comming soon ++

Events

• Board:
  • ready (when web socket is open for requests)
  • push (Is triggered when button is pressed)
• Relay:
  • relayStateIsChange (Is triggered when relay state is change)
• MOD-TC-MK2-31855 - temperature sensor
  • temperature (Return temperature value of MOD-TC-MK2-31855 module.Event trriger is based on your Poll settings on web based config page of the firmware)
• Finger Print Sensor
  • onFingerPrintDetected - When finger print is detected.

Methods

• Relay module:
  • setRelayState(param) - Change relay state with giving param, accept (1 or 0)
  • relayOn() - TurnOn the relay
  • relayOff() - TurnOff the relay
  • relayToggle() - Toggle relay state
• MOD-TC-MK2-31855 - temperature sensor
  • getTemperature() - Force emit temperature event to handle temperature.

Requirements

To use this you have to

1. Use Olimex IoT Firmware on your ESP8266-EVB - Link
2. Configure your computer as IoT Server using ESP-Sample-Application.html-link
   • Select IoT tab
   • Check WebSocket
   • Uncheck SSL
   • Set Server to your computer IP address
   • Leave everything else blank
   • (optimal) Fill name -- required for next updates
   • (optimal) Fill token -- required for next updates

3.Type following commands , but make sure you have already installed NPM and NodeJS

npm install esp8266-iotjs

4. Require 'esp8266-iotjs' in your code:

var esp8266 = require('esp8266-iotjs');
var board = new esp8266();

board.on("push",function(){
    console.log("button is pushed");
});

####Or

var esp8266 = require('esp8266-iotjs');
var board = new esp8266();

board.on('push',function(){
    this.relayToggle();
});

####Or if you wish make a termostat:

var ESP8266EVB = require('esp8266-iotjs');
var board = new ESP8266EVB();
var targetTemperature = 31;
var relayState = 0;
board.on('ready,function(){
    board.on('temperature',function(temperature){
        if(temperature < targetTemperature && relayState == 0){
            board.relayOn();
        }else if (temperature > targetTemperature && relayState == 1){
            board.relayOff();
        }
    });
});
