Script für BLU Wall Switch 4 ohne Cloud

[shelly_baer]

Hallo, falls es noch jemand gibt der die Cloud nicht mag aber den BLU4 einsetzen will, hier ein Script damit es auch ohne geht. Habe das Button-Script angepasst und es mit einer PlugPlusS getestet; funktioniert soweit. Das Script unterstützt pro Button Einzel-, Doppel-, Dreifach- und Lang-Click. Man trägt dann max 3 Actions pro Click in das Script ein. Und natürlich die MAC-Adresse.

Ist mein erster Versuch einer Scriptanpassung, also gerne verbessern.

/**
 * This script lets you use your Gen2 device as a gateway between Shelly BLU Wall Switch 4 and other Shelly devices (no matter Gen1 or Gen2)
 * by sending local requests by their local IP APIs.+
 * Based on the blu Button-Script
 * Script modifed by Joachim Reiter 2024
 * 
 * What you should change before using it:
 * > bluButtonAddress -> You should put the mac address of your blu button here.
 *                          This script will help you find the mac address: https://github.com/ALLTERCO/shelly-script-examples/blob/main/ble-shelly-scanner.js
 * 
 * > actions -> You should put the urls here to be executed at the specified event. Urls that shoudl be called on single/short push 
 *              of the button, must be placed in the singlePush object. This applies to the double and triple push as well. Example below.
 * 
 * Limitations:
 * > At the moment there is a limit of 5 RPC calls at the same time and because of this, the script will execute every 3 urls with a 1 second delay.
 *      Limitations can be check here: https://shelly-api-docs.shelly.cloud/gen2/Scripts/ShellyScriptLanguageFeatures#resource-limits
 * 
 * > The order of the execution of the urls can't be guaranteed

Danke dir, ich werde es bei Gelegenheit testen 👍🏻
