Basic usage example

import {
  Device,
  DeviceId,
  MdnsDeviceDiscoverer,
  Shellies,
  ShellyPlus1,
} from 'shellies-ng';

const shellies = new Shellies();

// handle discovered devices
shellies.on('add', async (device: Device) => {
  console.log(`${device.modelName} discovered`);
  console.log(`ID: ${device.id}`);

  // use instanceof to determine the device model
  if (device instanceof ShellyPlus1) {
    const plus1 = device as ShellyPlus1;

    // toggle the switch
    await plus1.switch0.toggle();
  }
});

// handle asynchronous errors
shellies.on('error', (deviceId: DeviceId, error: Error) => {
  console.error('An error occured:', error.message);
});

// create an mDNS device discoverer
const discoverer = new MdnsDeviceDiscoverer();
// register it
shellies.registerDiscoverer(discoverer);
// start discovering devices
discoverer.start();
