I've been around Arduino IDE for years. Primarily using ESP32's. So I bought a Arduino 33 Iot and thought Id give the Arduino Iot Cloud a go.
The follow is the Thing that was created. To me it's very straight forward.:
Thing Variable Names:
Zone1CloudSwitch zone1; true
Zone2CloudSwitch zone2; false
Zone3CloudSwitch zone3; false
Zone4CloudSwitch zone4; false
The following is the Scetch:
/*
Sketch generated by the Arduino IoT Cloud Thing "Untitled"
https://create.arduino.cc/cloud/things/94b8d542-8cb9-4849-a9dc-dca3fa393e14
Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
CloudSwitch zone1;
CloudSwitch zone2;
CloudSwitch zone3;
CloudSwitch zone4;
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.

}
else
digitalWrite(led1, HIGH);
// Add your code here to act upon Zone1 change
}

void onZone3Change() {

}
/

executed every time a new value is received from IoT Cloud.
*/
void onZone4Change() {
// Add your code here to act upon Zone4 change
}

Note: My relay board activates to a low state and I have only coded for Zone 1. The moment I put any code in the call routine "onZone1Change" routine the relay activates and the Zone1 Switch in the Dashboard won't turn off.
As I'm new to the Arduino Iot Cloud, perhaps I'm missing something. Thanks in advance for taking the time to read this topic.
