MeWo

A node-based WeMo emulator intended for use with the Amazon Echo. Largely ported from the python fauxmo.

What?

MeWo is the jumping off point for building custom on/off home automation scripts in node. It provides an interface for connecting to an Amazon Echo and performing whatever (on/off) tasks you want.

Installation

You will need to be running node 6 or later as MeWo makes use of ES6 features.

npm install --save mewo

Example Usage

 
const { UPnpBroadcastResponder, MeWoDevice } = require('mewo');
 
class MyUPnpDevice extends MeWoDevice {
  constructor(...args) {
    // Super must be called
    super(...args);
  }
 
  // Called when "alexa turn 'device' on" is said
  on() {
    return new Promise((resolve, reject) => {
      resolve();
    });
  }
 
  // Called when "alexa turn 'device' off" is said
  off() {
    return new Promise((resolve, reject) => {
      // Do something when the device is turned off
      resolve();
    });
  }
}
 
const responder = new UPnpBroadcastResponder();
responder.init({
  // These are the default options
  port: 1900,
  iface: 'eth0',
 
  // You may need to play around with this...
  multicastAddress: '239.11.3.8'
}).then(() => {
  // Create the new device with a name that will show up in the Alexa app
  const myDevice = new MyUPnpDevice('my-upnp-device', responder);
  // Register with the UPnP responder
  responder.registerDevice(myDevice);
});
