Switch sensor on and off using switch present in dashboard

I want to set up a toggle switch in dashboard in order to switch my PIR sensor ON and OFF. I mean when the PIR sensor is switched ON data should be sent to the dashboard in real time while as when the PIR sensor is switched OFF via toggle button in dashboard, it shouldn’t send any data because i dont need it on regular basis but i can’t find a way out.

add a button and use a if condition for the PIR sensor.

if(x == 1)
{
//PIR sensor reading.
}
CAYENNE_IN(1)
{
	int  x = getValue.asInt() ;

}

"expected unqualified-id before ‘if’ “.While compiling code this appears in the arduino IDE. I tried to keep it in void loop() which gives " ‘x’ was not declared in this scope” error.

int x; before void setup() and change

CAYENNE_IN(1)
{
	x = getValue.asInt() ;
}

place below code in void loop()

if(x == 1)
{
//PIR sensor reading.
}

I tried, but unfortunately not working… Here is my code… please check it and make some necessary alterations…

i cant find above code in your code.

Thank you for replying quickly… I apologize as i posted previous code…For making sure that the toggle switch on the cayenne dashboard is working , instead of sensor I tried the code on LED but LED isn’t working which means that the variable x isnt taking the value that is assigned to it in

CAYENNE_IN(1)
{
x = getValue.asInt() ;
}

your code is bit confusing.

does this work for you??

yes, flawlessly…

I really need to sort this problem out but I cant do it on my own… I have to submit my project next week.

so your entire code is working? your entire code is confusing .
