Zeroconf (LAN mode)

Zeroconf only works if you're connected to the same network of the device you wanna control.

Notes

• at this time, only turn on/off action is available.
• after initial setup, internet connection is not required to turn on/off your devices.

Introduction

Before start, you will need to create 2 files with information about your devices (the library includes methods to generate both files).

1. a cache file with information about your devices.
2. an "arp table" cache file with info from your network connected devices.
3. toggle specific device power state

1. Generate devices cache file

const ewelink = require('ewelink-api');

const connection = new ewelink({
  email: '<your ewelink email>',
  password: '<your ewelink password>',
  region: '<your ewelink region>',
});

await connection.saveDevicesCache();

A file named devices-cache.json will be created.

2. Generate arp table cache file

const Zeroconf = require('ewelink-api/src/classes/Zeroconf');

await Zeroconf.saveArpTable({
  ip: '<your network addres, ex: 192.168.5.1>'
});

A file named arp-table.json will be created.

3. toggle device power state

const ewelink = require('ewelink-api');
const Zeroconf = require('ewelink-api/src/classes/Zeroconf');

/* load cache files */
const devicesCache = await Zeroconf.loadCachedDevices();
const arpTable = await Zeroconf.loadArpTable();

/* create the connection using cache files */
const connection = new ewelink({ devicesCache, arpTable });

/* turn device on */
await connection.setDevicePowerState('<your device id>', 'on');

/* turn device off */
await connection.setDevicePowerState('<your device id>', 'off');
