Additional boards manager URLs

Community Help With My Project
1

I failed to connect my board to dashboard. i have ensure that there is no error on all of the wire connection and the codes. is there any additional boards manager URLs to be added in the IDE?

2

which device are you using?
also can you ask all your queries here in place of creating new topics.

3

i am using ESP32 to create a power monitor using few sensors which are DHT22, ACS712 and MQ135.
also i am using relay module to control the light bulbs via this platform.

can you share the code you are using and if any error while uploading.

Sure. I haven’t include for the bulb remote control yet. this only for the sensors.

can you run the below code and share the serial monitor output.

#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP32.h>

// WiFi network info.
char ssid[] = "ssid";
char wifiPassword[] = "wifiPassword";

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


void setup() {
	Serial.begin(9600);
	Cayenne.begin(username, password, clientID, ssid, wifiPassword);
}

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

// Default function for sending sensor data at intervals to Cayenne.
// You can also use functions for specific channels, e.g CAYENNE_OUT(1) for sending channel 1 data.
CAYENNE_OUT_DEFAULT()
{
	// Write data to Cayenne here. This example just sends the current uptime in milliseconds on virtual channel 0.
	Cayenne.virtualWrite(0, millis());
	// Some examples of other functions you can use to send data.
	//Cayenne.celsiusWrite(1, 22.0);
	//Cayenne.luxWrite(2, 700);
	//Cayenne.virtualWrite(3, 50, TYPE_PROXIMITY, UNIT_CENTIMETER);
}

// Default function for processing actuator commands from the Cayenne Dashboard.
// You can also use functions for specific channels, e.g CAYENNE_IN(1) for channel 1 commands.
CAYENNE_IN_DEFAULT()
{
	CAYENNE_LOG("Channel %u, value %s", request.channel, getValue.asString());
	//Process message here. If there is an error set an error message using getValue.setError(), e.g getValue.setError("Error message");
