Need Help ---- To make it work for ESP32 Board

[joykumarsen]

Hi,

First of all thank you for this tutorial.

can you please help me or guide me to make it work for ESP32 borad.
I taken the reference of your code.

issues --- I am not able to turn ON and OFF the lights. lights are getting on only while setting the brightness using Alexa command or Brightness slider in the Alexa app. Once the lights are ON, not able to make the lights OFF.

Your quick reply will be highly appreciable.

Below is the code what i am using for ESP32 board.

I'm not able to see any bug in the above code since it looks very similar to my alexa_sinric.ino code.

Please test each section of code separately.

if(action == "setPowerState") { // Switch or Light
        String value = json ["value"];
        if(value == "ON") {
            Serial.println("checking on");
            turnOn(deviceId);
        } else {
              Serial.println("checking off");
            turnOff(deviceId);
        }
    }

Add Serial.println("checking on"); and Serial.println("checking off"); and check if this line gets printed on serial monitor.
If this is working, you have to check turnOn and turnOff functions.
If this isn't working, Try to rewrite your code with sinric.pro (new version of Sinric) as you might face issue with older version (sinric.com )

Thank you for your quick reply and guidance.

After made the below changes, ON OFF part is working fine. But setBrightness part is stop working (Earlier the scenario was just reverse). you can check the attached Serial monitor screen shot as well for just reference.

As you told there might be issue with older version. Even in the sinric web site I have noticed that the service has been discontinued.
let's hope it should work with Sinric Pro!
