#include <TimeAlarms.h>
I have this class:

Code: Select allclass Device {
  public:
    int pin;//pin
    int enable;//enabled?
    int ON;//On or off?
    String itsName;//name
    boolean ScheduleForOn;//is it schedule to turn on?
    boolean ScheduleForOff;//is it schedule to turn off?
    void scheduleOn(){
      Serial.println(pin);
      Serial.println(" set to on by schedule");
      }
    void scheduleOff()
      {Serial.println(pin);
       Serial.println(" set to off by schedule");
        }
      };



Using TimerAlarms lib I want to set the "on" property of the device at a designated time.
I use this function:

Code: Select allDevice device[10];
  Serial.println(Alarm.alarmRepeat(13,55,50,device[0].scheduleOn);


but I get an error:

Code: Select allArduino: 1.6.9 (Windows 7), Board: "NodeMCU 1.0 (ESP-12E Module), 160 MHz, 115200, 4M (1M SPIFFS)"

I'm so confused of this void (*)() thing, I am missing something for sure!
device[0].scheduleOn(); works great!
What's that "onTickHandler" variable that the "AlarmRepeat" function gets?

The end result I need is:
user logs in and attaches an alarm to a device and when it goes off the device is turned on/off.
I thought about adding turnOn and turnOff functions to be called when the alarm goes off.
I'll use an index to the device I want to attach the alarm to like that:
Alarm.alarmRepeat(13,55,50,device[i].scheduleOn);
Any recommended ways to implement this?

Thanks for the help

Code: Select allclass Device {
  public:
    int pin;//pin
    int enable;//enabled?
    int ON;//On or off?
    String itsName;//name
    boolean ScheduleForOn;//is it schedule to turn on?
    boolean ScheduleForOff;//is it schedule to turn off?
    OnTick_t scheduleOn(){
      Serial.println(pin);
      Serial.println(" set to on by schedule");
      }
    OnTick_t scheduleOff()
      {Serial.println(pin);
       Serial.println(" set to off by schedule");
        }
      };
