Good evening friends, I need to include two relays in my project to connect two lamps. I’m using NodeMCU Esp8266. I have saved this code via IDE, but when I add new Widget (custom widgets / button) and added but I can not trigger the relay.
Code I used following the tutorial:
//#define CAYENNE_DEBUG
#define CAYENNE_PRINT Serial
#include <CayenneMQTTESP8266.h>
// WiFi network info.
char ssid = “((MP))”;
char wifiPassword = “xxxxxxx”;
// Cayenne authentication info. This should be obtained from the Cayenne Dashboard.
char username = “xxxxxxxxxxxxxxxxxxxxxx”;
char password = “xxxxxxxxxxxxxxxxxxxxxx”;
char clientID = “xxxxxxxxxxxxxxxxxxxxxxxx”;
unsigned long lastMillis = 0;
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”);
}
