@fagallo79,
I think the custom button may be broken.
I have been using this functionality in my BBQ project so I know it works.
Try this:
Add a new generic actuator
Set it to Virtual
Set your channel to 7
Select Button
Unfortunately, setting the channel is broken in the browser, but you can use the mobile app. Here’s a screen shot.
My BBQ code:
//#define CAYENNE_DEBUG // Uncomment to show debug messages
#define CAYENNE_PRINT Serial // Comment this out to disable prints and save space
#include <WiFi101.h>
#include <CayenneMKR1000.h>
#include <Timer.h>
#include <PID_v1.h>
#include <SPI.h>
#include <MAX31855_SPI.h>
//Define Variables we'll be connecting to
double Setpoint, Input, Output,PID_Input;
#define AugerPin 2
//Specify the links and initial tuning parameters
PID myPID(&Input, &Output, &Setpoint,0.5,1,5, DIRECT);
int WindowSize = 30000;
unsigned long windowStartTime;
byte cs = 0; //chip select is DIO 0
double internal_temp;
double coupler_temp;
MAX31855_SPI *max31855;
int running = 0;
Timer t;
// Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
char token[] = "";

{
max31855 = new MAX31855_SPI(cs);
SPI.begin();
//relays
pinMode(1,OUTPUT);
pinMode(2,OUTPUT);
pinMode(3,OUTPUT);
pinMode(4,OUTPUT);
//setup the pid
windowStartTime = millis();
//initialize the variables we're linked to
Setpoint = 100;
//tell the PID to range between 0 and the full window size
myPID.SetOutputLimits(0, WindowSize);
//turn the PID on
myPID.SetMode(AUTOMATIC);
Serial.begin(9600);
Cayenne.begin(token, ssid, password);
