Relay not working

Community Help With My Project
1

Hello folks,

Since the update Nothing work.

I have a relay using 3 channel and i am able to only make work one a the time.

here the code working for 1 channel :

/*
Cayenne Relay Switch Example

This sketch sample file shows how to set up a Relay Switch with Cayenne.

The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.

Steps:
1. In the Cayenne Dashboard add a new Relay Switch widget.
2. Select a virtual channel number for the widget.
3. Set the VIRTUAL_CHANNEL value below to the virtual channel you selected.
4. Connect your relay switch to a digital pin.
5. Set the ACTUATOR_PIN value below to the digital pin number you selected.
6. Set the Cayenne authentication info to match the authentication info from the Dashboard.
7. Compile and upload this sketch.
8. Once the Arduino connects to the Dashboard you can use the widget button to turn the relay switch on and off.
*/

#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space
#include <CayenneMQTTEthernet.h>

// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username[] = "16";
char password[] = "";
char clientID[] = "6";

#define VIRTUAL_CHANNEL 3
#define ACTUATOR_PIN 4 // Do not use digital pins 0 or 1 since those conflict with the use of Serial.

void setup()
{
  Serial.begin(9600);
  pinMode(ACTUATOR_PIN, OUTPUT);
  Cayenne.begin(username, password, clientID);
}

void loop()
{
  Cayenne.loop();
}

// This function is called when data is sent from Cayenne.
CAYENNE_IN(VIRTUAL_CHANNEL)
{
	// Write value to turn the relay switch on or off. This code assumes you wire your relay as normally open.
	if (getValue.asInt() == 0) {
		digitalWrite(ACTUATOR_PIN, HIGH);
	}
	else {
		digitalWrite(ACTUATOR_PIN, LOW);
	}
}

So i though to add my other relay i should add the following line

#define VIRTUAL_CHANNEL 3
#define ACTUATOR_PIN 4 // Do not use digital pins 0 or 1 since those conflict with the use of Serial.
#define VIRTUAL_CHANNEL 5
#define ACTUATOR_PIN 3 // Do not use digital pins 0 or 1 since those conflict with the use of Serial.
#define VIRTUAL_CHANNEL 4
#define ACTUATOR_PIN 2 // Do not use digital pins 0 or 1 since those conflict with the use of Serial.

It’s work once and then Nothing so if i switch the actuactor pin i able to make work different channel on the relay but only one a the Time

I don’t get what have changed from before

Appreciate any help thanks

change

to #define VIRTUAL_CHANNEL_1 5 and #define VIRTUAL_CHANNEL_2 4.

you need to add more two of this function to read status and turn on relay for respective virtual channel and actuator pin.

3 
#define VIRTUAL_CHANNEL1 1
#define ACTUATOR_PIN4 4

CAYENNE_IN(VIRTUAL_CHANNEL1)
{
	if (getValue.asInt() == 0) {
		digitalWrite(ACTUATOR_PIN4, LOW);
	}
	else {
		digitalWrite(ACTUATOR_PIN4, HIGH);
	}
}

ok thanks for your help i gonna try that.

I have the same issue of the creator of this post, and i can solved it with the replys you write here. Thank you very much!!

This worked for me once I paid attention to details. Funny how that works.

Hey there @flammeur Make sure to delete you credentials when you post your sketch. Anyone could highjack your board or worse.

Time to edit.
