Control TP-Link smart-home devices from nodejs

NPM

This will allow you to control TP-Link smart-home devices from nodejs or the command-line.

  • If you want to use kasa (allows you to hit your tplink devices, on an external network) have a look at kasa_control.
  • If you'd like to run a GraphQL server to control your lights, see tplink-graphql.
  • If you like to see a demo web-app that uses react & websockets, see tpserver.

supported devices

Not all TP-Link smart-home devices can do all things, here's the support-matrix:

LB130 X X X X X X X X X X

I have LB120, LB130, and HS105, so any testing (and packet-capture) with other devices would be greatly appreciated.

command-line

If you have nodejs installed, you can install it for your system with this:

npm i -g tplink-lightbulb

You can even run it without installing:

npx tplink-lightbulb

If you don't want to install nodejs, or just want the standalone-version, install a release for your system.

Now, you can use it like this:

Usage: tplight <COMMAND>

Commands:
  tplight scan                               Scan for lightbulbs

wireshark

If you want to analyze the protocol, you can use the included tplink-smarthome.lua.

Install in the location listed in About Wireshark/Folders/Personal Plugins

I captured packets with tcpdump running on a raspberry pi pretending to be a router. In general, this is a really useful way to capture IOT protocols and mess around with them.

I ssh'd into my pi, ran sudo apt update && sudo apt install tcpdump, then tcpdump -i wlan0 -w lights.pcap

I connected the lights to that network (reset them to factory default by turning the power off/on 5 times, then configure in Kasa app.)

After I did stuff like switch the lights on/off in app, I open the pcap file in wireshark on my desktop.

library

You can install it in your project like this:

npm i -S tplink-lightbulb

Include it in your project like this:

const TPLSmartDevice = require('tplink-lightbulb')

or for ES6:

import TPLSmartDevice from 'tplink-lightbulb'
