Homie2Config

Homie2Config is a node.js module to configure esp8266 boards loaded with Homie firmware.

This is for Homie version 2.0+, original codebase from HomieConfig

QuickStart

You can grab homie2-config from npm.

npm install --save homie2-config

Make sure to set an ip address or hostname for the board. By default, 192.168.123.1 is used in case you don't pass anything.

var Homie2Config = require('homie2-config');

var homie2 = new Homie2Config();

If you want to set the url/ip you can do it this way:

var homie2 = new Homie2Config({url: 'homie.local'});

Traditional Callbacks

// You can choose to use traditional callbacks
homie2.getHeartBeat(function(isAlive) {
  if (!isAlive) {
    return console.log("Oh no, we don't have a heartbeat!");
  }
  console.log("We have a heartbeat!");
});

Promises are also supported by attaching (async) to method names

homie2.getHeartBeatAsync()
  .then(function(isAlive) {
    if (!isAlive) {
      console.log("Oh no, we don't have a heartbeat! Please check the server url " + this.baseUrl);
    }
    console.log("We have a heartbeat!");
  }).catch(function (error) {
    console.log('error',error);
  });

You can chain up the methods easily using promises. I recommend you always use getHeartBeat before other methods.

homie2.getHeartBeatAsync()
  .then(function(isAlive) {
    if (!isAlive) {
      console.log("Oh no, we don't have a heartbeat! Please check the server url " + this.baseUrl);
    }
    return homie2.getDeviceInfoAsync();
  }).then(function(deviceInfo) {
    console.log('Device Info', deviceInfo);
  }).catch(function (error) {
    console.log('error',error);
  });

Please find more examples in the examples directory.
