I am trying to use IoT Cloud to be able to control some lights using Google Home. I have created 5 variables there (once using CloudLight, once using CloudSwitch) and have integrated my thing with Google Home. These variables update correctly when I turn them on or off on my phone, but my code doesn't seem to reflect that, as they always stay at "false".
I have this code, partially generated by AI (I was desperate).
#include "arduino_secrets.h"
#include "thingProperties.h"
#include <WiFi.h> // Include the WiFi library for ESP32
/*
Sketch generated by the Arduino IoT Cloud Thing "Untitled"
https://create.arduino.cc/cloud/things/3043cf77-3b19-4f99-b247-fcd202a2dd05
Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
CloudSwitch luz_garagem;
CloudSwitch luz_quarto_direita;
CloudSwitch luz_quarto_esquerda;
CloudSwitch luz_quarto_tras;
CloudSwitch luz_sala;
Variables which are marked as READ/WRITE in the Cloud Thing will also have functions
which are called when their values are changed from the Dashboard.
These functions are generated with the Thing and added at the end of this sketch.
