WOW!!! Whats wrong?

make sure you have cayenneMQTTesp8266 library installed.
on your dashboard add a new device using “Bring Your Own Thing” and copy the MQTT credential into below code and upload in Wemos with correct board selected.

// This example shows how to connect to Cayenne using an ESP8266 and send/receive sample data.
// Make sure you install the ESP8266 Board Package via the Arduino IDE Board Manager and select the correct ESP8266 board before compiling. 

//#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP8266.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";

unsigned long lastMillis = 0;

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

void loop() {
	Cayenne.loop();

	//Publish data every 10 seconds (10000 milliseconds). Change this value to publish at a different interval.
	if (millis() - lastMillis > 10000) {
		lastMillis = millis();
		//Write data to Cayenne here. This example just sends the current uptime in milliseconds.
		Cayenne.virtualWrite(0, lastMillis);
}
}

Thanks, already change library to Cayenne-MQTT-ESP! I’m happy!

shramik_salgaonkar · February 19, 2018, 1:35pm

so is it working now?

zolandv · February 19, 2018, 1:41pm

One time was success, but after adding my sensors locked after connecting to my WiFi (((

By the way - where can I find description of library calls,

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, bme.readTemperature());
Cayenne.hectoPascalWrite(2, bme.readPressure());
Cayenne.luxWrite(3, LightSensor.getAmbientLight());
//Cayenne.virtualWrite(3, 50, TYPE_PROXIMITY, UNIT_CENTIMETER);
}

I find only temp, pressure and lux… I’ll try to organise first my Meteo station

Many thanks for your help

zolandv · February 19, 2018, 1:43pm

And where can I find description of usage CAYENNE_OUT(xxx)?

// You can also use functions for specific channels, e.g CAYENNE_OUT(1) for sending channel 1 data.

all the supported data types: Cayenne Features - Developer | myDevices.com

zolandv · February 19, 2018, 4:28pm

OK, thanks
It;s seemd that my WiFi time to time blocked…

But anyway, is somewere functions and it’s parameters description, or, maybe CLASSes descriptoin - how they can be used?
