Storing data

Community Help With My Project
1

Hi,
I made a project with nodeMCU ESP8266 and DS18b20 and relay. It is working fine. i can switch the relay and can see the temperatures. The problem is that temperatures are stored in the cloud only when i am login in. There is no data when i am no login in to mydevice. What could be the problem?

When you say there is no data when you are not logged in, what are you logging in to?

Are you using the sleep function in your sketch? Is anything shown on hour/day?

Not that I know about. I don’t think so but i am using wifi nodemcu.
The code look like below
Sometimes i can see the live view and minute view but don’t know whats the key for displaying.
Right now i can see the day and week view but with strange hour view

#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space

#include <ESP8266WiFi.h>
#include "CayenneDefines.h"
#include "BlynkSimpleEsp8266.h"
#include "CayenneWiFiClient.h"

#include <Wire.h>
//Wirtualne porty dla cayenne
#define VIRTUAL_PIN V1
#define VIRTUAL_PIN V2

#include <DallasTemperature.h>
#include<OneWire.h>
#define ONE_WIRE_BUS 2
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "mytoken";

char ssid[] = "xxxxx";
char password[] = "xxxxx";

IPAddress ip;
unsigned long previousMillis = 0;
unsigned long lastTempUpdate = 0;

int mq2 = A0;

void setup()
{
  Serial.begin(115200);
  sensors.begin();
  delay(10);
  pinMode(mq2, INPUT);

  sensors.begin();
  Cayenne.begin(token, ssid, password);

}



// ==============( Void Loop  ) ====================================

void loop() {
  Cayenne.run();
  sensors.requestTemperatures();
  int temp1 = sensors.getTempCByIndex(0);
  int mq2read = analogRead(mq2);

  delay(200);
  unsigned long now = millis();

  if ( now - lastTempUpdate > 600 ) {
    String MyIp;
    String Both;
    MyIp =  "IP: " + String(WiFi.localIP()[0]) + "." + String(WiFi.localIP()[1]) + "." + String(WiFi.localIP()[2]) + "." + String(WiFi.localIP()[3]);
    String MyWiFi;
    MyWiFi = "WiFi: " + String(WiFi.RSSI());
    Serial.println(MyIp);
    Serial.println(MyWiFi);

    Serial.println(temp1);
    Serial.println(mq2read);
    Cayenne.virtualWrite(V1, temp1);
    Cayenne.virtualWrite(V2, mq2read);

    lastTempUpdate = now;
  }

}

Try this:

#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space

#include <ESP8266WiFi.h>
#include "CayenneDefines.h"
#include "BlynkSimpleEsp8266.h"
#include "CayenneWiFiClient.h"

#include <Wire.h>
//Wirtualne porty dla cayenne
#define VIRTUAL_PIN V1
#define VIRTUAL_PIN V2

#include <DallasTemperature.h>
#include<OneWire.h>
#define ONE_WIRE_BUS 2
OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature sensors(&oneWire);
// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "mytoken";

char ssid[] = "xxxxx";
char password[] = "xxxxx";

IPAddress ip;
//unsigned long previousMillis = 0;
unsigned long lastTempUpdate = 0;

int mq2 = A0;

void setup()
{
  Serial.begin(115200);
  sensors.begin();
  delay(10);
  pinMode(mq2, INPUT);

  sensors.begin();
  Cayenne.begin(token, ssid, password);

}



// ==============( Void Loop  ) ====================================

void loop() {
  Cayenne.run();
  sensors.requestTemperatures();
  int temp1 = sensors.getTempCByIndex(0);
  int mq2read = analogRead(mq2);

  delay(200);
  //unsigned long now = millis();

  //if ( now - lastTempUpdate > 600 ) {
    if ( millis() - lastTempUpdate > 600 ) {
	    lastTempUpdate = millis();
	
    String MyIp;
    String Both;
    MyIp =  "IP: " + String(WiFi.localIP()[0]) + "." + String(WiFi.localIP()[1]) + "." + String(WiFi.localIP()[2]) + "." + String(WiFi.localIP()[3]);
    String MyWiFi;
    MyWiFi = "WiFi: " + String(WiFi.RSSI());
    Serial.println(MyIp);
    Serial.println(MyWiFi);

    Serial.println(temp1);
    Serial.println(mq2read);
    Cayenne.virtualWrite(V1, temp1);
    Cayenne.virtualWrite(V2, mq2read);

    //lastTempUpdate = now;
  }

}
