node-samsung-aircon

An attempt to refactor the node-samsung-airconditioner library to use promises. Of course, this is not a bullet proof solution, because we connect to a socket that sends events...

However, for basic use cases like connecting, reading a status and change a value it works fine. And for other use cases it's probablby flawed and buggy. Please submit an issue if anything strange is found.

Installation

npm i node-samsung-aircon -S

Examples

The main function in all examples below are called like this:

main()
.then(() => process.exit(0))
.catch(err => {
  console.log('ERROR!', err);
  process.exit(1);
});

With promises

import SamsungDiscovery, { Utils } from 'node-samsung-aircon';
 
async function main() {
  // Create a discovery (with an optional logger)
  const discovery = new SamsungDiscovery().withLogger(console);
  const [aircon] = await discovery.discover();
 
  // Found device(s), we can now stop to discover more
  discovery.stop();
 
  // If a token is not supplied, just follow the
  // instuctions when prompted to power on the AC
  // and write down the token for the future.
  await aircon.login(process.env.TOKEN);
 
  // Wait before we ask for status (due to promises and events)
  // below is also an example where we consume events.
  await Utils.sleep(2000);

  const status = await aircon.fetchStatus();
  console.log({ status });
}

With promises (and events)

import SamsungDiscovery, { Utils } from 'node-samsung-aircon';

async function main() {
  const discovery = new SamsungDiscovery();
  const [aircon] = await discovery.discover();
 
  // Found device(s), we can now stop to discover more
  discovery.stop();

  // Consume events
  aircon.on('read', line => {
    console.log('Read line', line);
  });
 
  aircon.on('state', state => {
    console.log('New state', state);
  });

  await aircon.login(process.env.TOKEN);
  await Utils.sleep(2000);

  await aircon.setTemp('22');
  await Utils.sleep(2000);

  await aircon.fetchStatus();
  await Utils.sleep(2000);
}
