ESP 8266 problem

I am working with a ESP8266 development board. I have programmed it with Arduino IDE. I used #include <ESP8266WiFi.h> for the Wifi Connection and #include <CayenneMQTTESP8266.h> for the Cayenne connection. I add a button widget on channel 1 to control the pin 16 with a led attached and i use CAYENNE_OUT_DEFAULT() to send millis()/1000 on channel 0. Using the browser i can see all well working, while using the Cayenne app on two cellular only when i enter the device i can see the right values but i ca’nt send commands. Do you have an idea?
