Hallo, anbei ein Script damit der BLU4 auch ohne Cloud und Internet geht. Habe das Blu-Button-Script angepasst und es mit einer PlugPlusS getestet; funktioniert soweit. Das Script unterstützt pro Button Einzel-, Doppel-, Dreifach- und Long-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.
Code
/**
* 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
*/
