Introduction

The tplink-cloud-api NPM module allows your to remotely control your TP-Link smartplugs (HS100, HS110), smart switches (HS200), and smartbulbs (LB100, LB110, LB120, LB130) using the TP-Link cloud web service, from anywhere, without the need to be on the same wifi/lan.

It's especially useful in scenarios where you want to control your devices from public web services, like IFTTT, Thinger.io, Webtasks.io, Glitch.com...

It's based on my investigation work on the TP-Link API protocol, which I have been sharing in my blog http://itnerd.com.

Installation

You can install this module with npm:

npm install --save tplink-cloud-api

Usage

Authenticate

First instantiate a TP-Link object. TermID (UUIDv4) is generated if not specified:

const { login } = require("tplink-cloud-api");
const tplink = await login("[email protected]", "Password", "TermID");

Retrieve devices

Once authenticated, you can use your tplink instance to retrieve the list of your devices:

let deviceList = await tplink.getDeviceList();

Control your devices

Smartplugs (HS100 & HS110)

Now you can toggle a plug:

await tplink.getHS100("My Smart Plug").toggle();

You can also create an object and use it like this:

let myPlug = tplink.getHS100("My Smart Plug ");
let response = await myPlug.toggle();
console.log(await myPlug.getRelayState());

Replace My Smart Plug with the alias you gave to your plug in the Kasa app (be sure to give a different alias to each device).

Instead of toggle(), you can use powerOn() or powerOff(). See all available methods below.

If you want to trigger multiple plugs, you can do it like this:

await tplink.getHS100("My Smart Plug").toggle();
await tplink.getHS100("My Smart Plug 2").powerOn();
await tplink.getHS100("My Smart Plug 3").powerOff();
await tplink.getHS100("My Smart Plug 4").powerOff();

To retrieve power consumption data for the HS110:

await tplink.getHS110("My Smart Plug").getPowerUsage();

Smart Switches (HS200)

You can toggle smart switches with the same API as the smart plugs.

Smartbulbs (LB100/110/120/130)

If you have an LB100/110/120, you can change it's state with:

await tplink.getLB100("Bedroom LB120").setState(1, 90);

The two parameters are:

• on_off: 1 on, 0 on_off
• brightness: 0-100

If you have an LB130, use this:

await tplink.getLB130("Kitchen LB130").setState(1, 90, 150, 80);

The four parameters for LB130 are:

• on_off: 1 on, 0 on_off
• brightness: 0-100
• hue: 0-360
• saturation: 0-100

For help to choose the hue/saturation value, you can head to http://colorizer.org/.

Example

const { login } = require("tplink-cloud-api");
const uuidV4 = require("uuid/v4");

const TPLINK_USER = process.env.TPLINK_USER;
const TPLINK_PASS = process.env.TPLINK_PASS;
const TPLINK_TERM = process.env.TPLINK_TERM || uuidV4();

async function main() {
  // log in to cloud, return a connected tplink object
  const tplink = await login(TPLINK_USER, TPLINK_PASS, TPLINK_TERM);
  console.log("current auth token is", tplink.getToken());

  // get a list of raw json objects (must be invoked before .get* works)
  const dl = await tplink.getDeviceList();
  console.log(dl);

  let myPlug = tplink.getHS100("My Smart Plug");
  console.log("deviceId=", myPlug.getDeviceId());

  //let response = await myPlug.powerOn();
  //console.log("response=" + response );

  let response = await myPlug.toggle();
  console.log("response=" + response);

  response = await myPlug.getSysInfo();
  console.log("relay_state=" + response.relay_state);
  //console.log( JSON.parse(response).relay_state );

  console.log(await myPlug.getRelayState());

  // alternatively, map to light or plug objects that can directly be invoked (eg: .transitionLightState(...))
  for (const d of rawDevices) {
    const device = tplink.newDevice(d);

    if (device.disconnected) {
      // aka !connected
      continue; // can't operate on a device that's not connected to the internet
    }

    console.log(
      device.type,
      "(",
      device.genericType,
      ") in",
      device.humanName,
      "is..."
    ); // IOT.SMARTBULB (bulb) in Living Room is...

    if (device.genericType === "bulb") {
      // LB* type object
      // alias is the same as humanName
      if (device.alias === "Living Room") {
        // can be replaced by .toggle(), but written here for verbosity
        if (!(await device.isOn())) {
          console.log("off. turning on...");
          await device.powerOn();
        } else {
          console.log("on. turning off...");
          await device.powerOff();
        }
      }
    } else if (device.genericType === "plug") {
      // HS* type object
      if (!(await device.isOff())) {
        device.powerOff();
      }
    } else {
      // we haven't written the code... yet!
    }
  }
}

main();

Available methods

TPLink class

login()

This constructor method authenticates against the TP-Link cloud API and retrieves a token.

Parameters

Parameter	Specification	Description
user	String	TP-Link account user name
password	String	TP-Link account password
termid	UUIDv4 String	Your client application Terminal ID

termid is an arbitrary value. The API expects a UUIDv4 string, but at this time it doesn't validate this.

Returns

Returns the TPLink instance that you can later use to retrieve the Device List.

getDeviceList()

This method returns an object that describe all the TP-Link devices registred to this TP-Link account.

You need to call this method once after login() in order to be able to get a particular device. Call this method every time you need to refresh the list of devices.

Parameters

None

Returns

Returns an object that describe all the TP-Link devices registred to this TP-Link account.

Requires

Requires Node.js > v7.7 (async)
