My dashboard wont show numbers even though I have connected all the variables and etc. I have an opla, and I can see everything on the LED screen, but the dashboard wont work (web nor mobile app).
here is my code if it helps:
#include <Wire.h>
#include "thingProperties.h"
#include <Arduino_MKRIoTCarrier.h>
#include <Arduino_OplaUI.h>
// Constant for dry sensor
const int DryValue = 4095;
// Constant for wet sensor
const int WetValue = 3100;
// Variables for soil moisture
int soilMoistureValue;
int soilMoisturePercent;
// Analog input port
#define SENSOR_IN A6
const int moistPin = A6;
#define SENSOR_IN A5
const int humidityPin = A5;
unsigned long startedWatering;

}
opla.leds.show();
// Stop watering after the configured duration
if (watering && (millis() - startedWatering) >= waterTime*1000) {
stopWatering();
}
delay(100);
}
// This function is triggered whenever the server sends a change event,
// which means that someone changed a value remotely and we need to do
// something.
