TPLinkKasa - Stand-alone php Class providing access to TPLink KASA HS100-Family Cloud-Controlled WiFi-Switches

Author: rh1492raw@gmail.com License: none Relates to / Inspired by: https://github.com/TheHackLife/TPLink-hs100-PHP-REST-API/blob/master/tplink.class.php

My thanks to to [Joan "TheHackLife" Manual (https://github.com/TheHackLife)] for providing the base logic (API reverse engineering) of this package

Pre-requisites

It just needs a basic php7.3++ Environment.

Outline

This Class can be used to switch TP Link KASA HS100-Family WiFi-Switches (HS-100/HS110) The builds a basis for extending it to other devices API calls are provided as granular functions constructor is built with file "caching" to avoid redundant repeated calls to the KASA API but depends on whether the PHP-Code can write in the local folder (location of the library)

Some details

A capability toggle (PHP_CAN_WRITE_TO_FILES_IN_PACKAGE_FOLDER) can be used to turn the file "caching" off. Rewritten php TP Link Kasa Library https://github.com/TheHackLife/TPLink-hs100-PHP-REST-API/blob/master/tplink.class.php

added local file caching
added method phpDocs and comments
separted queries and extracted some reused constants
divided it into granular, resuable methods

Class TPLinkKasa

 constructor: establishes the connection and authentication, has switches to force a re-authentication or a refetch of the device list
 sendQuery:     runs a sendQuery
 getDeviceList: get list of devices (from cached file devices.json or the internet)
 togglePlugbyId(): toggle the relais switch of Plug x by ID
 togglePlugByName(): toggle the relaisswitch of Plug x by togglePlugByName
 ...

Possible Improvements:

App throws lots of exceptions in many situations - maybe build a centralized error handler
Caching abstraction - Relying on writing local files might be more than standard server environments offer (see PHP_CAN_WRITE_TO_FILES_IN_PACKAGE_FOLDER switch)

Basic Usage

Initialization

     include 'TPLinkKasa.php';
     // Try using "cached" logins, if not available, login and fetch device list, store ClientID, Authentication Token and Device list in "cache" files for reuse
     $myTPLink = new TPLinkKasa(<username>, <password>, false , false);

Toggle a plug (relay) by alias (name)

    $myTPLink->togglePlugByName(<PlugAliasName>);

Set a plug state

    $deviceId = $myTPLink->getDeviceIDbyName(<PlugAliasName>);
    $simplifiedDeviceList= $myTPLink->getDevicesById();
    $appServerUrl = $simplifiedDeviceList['deviceURL'];
    $myTPLink->setPlugState(true,$deviceId,$appServerUrl); // Turn device on
    $myTPLink->setPlugState(false,$deviceId,$appServerUrl); // Turn device off

Get a plug state

(with deviceId and appServerUrl as above)

    $myTPLink->getPlugStateBool($deviceId, $appServerUrl);

How I use it

I put a basic constructor and toggle command in a file on my webserver and toggle it via a JS bookmark:

   javascript:(function () { window.open('http://localhost/tplink/myTPLink.php','_blank');})();

More Features?

The package is self-explanatory using phpDoc and lots of comments. Therefore, it can be extended easily. I am happy to add contributors...
