I've been trying to update the esp32 led through node js.
I also updated the variable value true/false through Arduino cloud API publish property and it does reflect on the cloud.
But when it updates it's not reflected on the ESP32 and the led is not on/off , though when i try the same with the dashboard it works perfectly fine.
Any Suggestions?
Here is my sketch code.
/*
Sketch generated by the Arduino IoT Cloud Thing "Untitled"
https://create.arduino.cc/cloud/things/****
Arduino IoT Cloud Variables description
The following variables are automatically generated and updated when changes are made to the Thing
CloudLight led;
CloudTemperatureSensor temperature;
CloudRelativeHumidity humidity;
String Wifi_SSID;
String wifi_PWD;
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.
