Blynk Edgenet Configuration error

Need Help With My Project
1

Hey, i’m having trouble with one of my projects. I was trying to build a home automation system which remembers the previous state in case of a power loss, but after uploading the code I’m not able to connect my Node MCU esp-12E with the blynk app.

#include <EEPROM.h>

#define BLYNK_TEMPLATE_ID "TMPLBzK5MDXo"

int fan_Speed1 = HIGH;
int fan_Speed2 = HIGH;
int fan_Speed3 = HIGH;
int fan_Speed4 = HIGH;

int Speed1 = 14;
int Speed2 = 12;
int Speed3 = 4;
int Speed4 = 5;

int Speed1add = 1;
int Speed2add = 2;
int Speed3add = 3;
int Speed4add = 4;

BLYNK_WRITE(V12)
{
  fan_Speed1 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed1, fan_Speed1);
  EEPROM.write(Speed1add, fan_Speed1);
  EEPROM.commit();
}

BLYNK_WRITE(V13)
{
  fan_Speed2 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed2, fan_Speed2);
  EEPROM.write(Speed2add, fan_Speed2);
  EEPROM.commit();
}

BLYNK_WRITE(V14)
{
  fan_Speed3 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed3, fan_Speed3);
  EEPROM.write(Speed3add, fan_Speed3);
  EEPROM.commit();
}

BLYNK_WRITE(V15)
{
  fan_Speed4 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed4, fan_Speed4);

  }

  }
  else
  {
    fan_Speed3 = EEPROM.read(Speed3add);
  }
  if (EEPROM.read(Speed4add) == 255)
  {
    fan_Speed4 = HIGH;//default turn off value for relay
  }
  else
  {
    fan_Speed4 = EEPROM.read(Speed4add);
  }
  
  
  pinMode(Speed1, OUTPUT);
  pinMode(Speed2, OUTPUT);
  pinMode(Speed3, OUTPUT);
  pinMode(Speed4, OUTPUT);

  //TURN OFF all Relays on Start 
  digitalWrite(Speed1, fan_Speed1);
  digitalWrite(Speed2, fan_Speed2);
  digitalWrite(Speed3, fan_Speed3);
  digitalWrite(Speed4, fan_Speed4);

  Serial.begin(115200);

  Serial.println("Begin");
  
  delay(100);
  BlynkEdgent.begin();
}

void loop() {
  BlynkEdgent.run();
}

After Uploading the output is this

Blynk Edgent uses EEPROM to store the Auth token and WiFi credentials, so there a good chance that you are overwriting that info with your EDPROM code - hence the constant request for you to clear tge EEPROM by pressing the button for 10 seconds then re-provision the device.

TBH, you’d probably be better storing the last state on te Blynk server then fetching this whth a Blynk.sync(vPin) command within a BLYNK_CONNECTED callback.

So this is what you are suggesting

#define BLYNK_TEMPLATE_ID "TMPLBzK5MDXo"
#define BLYNK_DEVICE_NAME "HomeUTOMATION"

#define BLYNK_FIRMWARE_VERSION        "0.1.0"

#define BLYNK_PRINT Serial
//#define BLYNK_DEBUG

#define APP_DEBUG

// Uncomment your board, or configure a custom board in Settings.h
//#define USE_SPARKFUN_BLYNK_BOARD
#define USE_NODE_MCU_BOARD
//#define USE_WITTY_CLOUD_BOARD
//#define USE_WEMOS_D1_MINI

#include "BlynkEdgent.h"

int fan_Speed1 = HIGH;
int fan_Speed2 = HIGH;
int fan_Speed3 = HIGH;
int fan_Speed4 = HIGH;

int Speed1 = 14;
int Speed2 = 12;
int Speed3 = 4;
int Speed4 = 5;

BLYNK_WRITE(V12)
{
  fan_Speed1 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed1, fan_Speed1);
}

BLYNK_WRITE(V13)
{
  fan_Speed2 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed2, fan_Speed2);
}

BLYNK_WRITE(V14)
{
  fan_Speed3 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed3, fan_Speed3);
}

BLYNK_WRITE(V15)
{
  fan_Speed4 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed4, fan_Speed4);
}

void setup()
{
  pinMode(Speed1, OUTPUT);
  pinMode(Speed2, OUTPUT);
  pinMode(Speed3, OUTPUT);
  pinMode(Speed4, OUTPUT);

  //TURN OFF all Relays on Start 
  digitalWrite(Speed1, fan_Speed1);
  digitalWrite(Speed2, fan_Speed2);
  digitalWrite(Speed3, fan_Speed3);
  digitalWrite(Speed4, fan_Speed4);

  Serial.begin(115200);

  Serial.println("Begin");
  
  delay(100);
  BlynkEdgent.begin();
}

void loop() {
  BlynkEdgent.run();
}

BLYNK_CONNECTED(){
  Blynk.syncAll();
  }

No, I said…

not

I don’t understand can you please provide me with a code snippet with that implementation?
I’m Sorry I’m something of a beginner with blynk.

-edit-
Is This Right? If not can please provide me with the snippet

BLYNK_CONNECTED(){
  Blynk.syncVirtual(V12,V13,V14,V15);
}

BLYNK_WRITE(V12)
{
  fan_Speed1 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed1, fan_Speed1);
}

BLYNK_WRITE(V13)
{
  fan_Speed2 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed2, fan_Speed2);
}

BLYNK_WRITE(V14)
{
  fan_Speed3 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed3, fan_Speed3);
}

BLYNK_WRITE(V15)
{
  fan_Speed4 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed4, fan_Speed4);
}

Thank you

Does this actually work?

I’d have expected four lines of code, one for each vPin.

Pete.

7

Also, your approach seems rather clunky.
Why not use a segmented switch or a slider with values for each speed, then with a 0 value for off, or an on/off switch?

Pete.

Oh sorry if you misunderstood the code. I was reusing the code from one of my old legacy blynk projects which acted as a Speed Controller for my fan, but this one is for controling 4 different appliances. Because of this reuse the variable names can be a bit confusing.

Thank you though.

So this is the code to achieve what I’m trying to do?

BLYNK_CONNECTED(){
  Blynk.syncVirtual(V12);
  Blynk.syncVirtual(V13);
  Blynk.syncVirtual(V14);
  Blynk.syncVirtual(V15);
}

BLYNK_WRITE(V12)
{
  fan_Speed1 = param.asInt(); // assigning incoming value from pin V1 to a variable
  digitalWrite(Speed1, fan_Speed1);
}
..........
