Loop and publish variable

Firmware
1

I am having a little trouble with the looping of a variable being published. In short I am unable to adjust the time between publishing, either it doesn’t publish or it publishes ever hour.

I have tried delay, sleep and time now with set wait times.

Current firmware I am running is below;

int analogvalue = 0;
int boardLed = D7; // LED
int moister_value = 0;
char *message = "Kentia_P02";



void setup()
{
  Particle.variable("Unit", message, STRING);
  pinMode(boardLed,OUTPUT);
  pinMode(A1, INPUT);
}

void loop()
{
    digitalWrite(boardLed,HIGH);
    analogvalue = analogRead(A1);
    moister_value = (100 - ( (analogvalue/4095.00) * 100 ) ); // read capacitive sensor
    Particle.variable("moister", &moister_value, INT);
    delay(4000);
    digitalWrite(boardLed,LOW);
    // put device to sleep for 1 hours (3600 seconds)
    //System.sleep(D1,RISING,3600);
    //delay(360000);
}

I’d be grateful if someone can put me on the right track.

Particle.variable() is not to be called multiple times for the same variable.
You register a global variable (or function) once in setup() and from then on whenever the cloud requests that variable the value of that variable/function will be sent back.

Also a Particle.variable() is never published/pushed but needs to be requested.
If you want to push data you’d use Particle.publish() (at a rate of no more than 1/second).

BTW, your syntax is outdated.
The correct (current) form is Particle.variable("moister", moister_value);

In addition: Have you tried researching that question in the forum before posting?
