Relay timer issue not looping

/*
Timer relay control set up for 4 relay unit.
Each relay is individually controlled.
 */

// Questions?  Ask them here: Hi Guys new to Arduino as you will see trying to get a 4 channel relay to work based on time of day for a Aquaponics setup, it will work for the first section of Alarm.alarmRepeat and then stop. I'm fairly confident that's its not looping through the pump controls functions, i need a loop function for the time and also for the pump control. Don't know how to use a while loop to control. if you could help that would be appreciated. Regards Damien.

Never used the alarm library but I suggest You go back to its documentation and read the lines You have not been reading yet.
Is that all that's needed, calling Alarm.delay? I suggest investigating that.

Thanks Railroader (me too work with track machines) yes all I need is a nice way to continue looping through the code for the time. I’ll have a look at the documentation and see what I’m missing I’m sure it’s a bit. Thanks for the help.

Hi,
I tested your code here and the same problem occurred.
But I identified that the code is executed with the first 6 events of alarmRepeat():

So I modified your code for simplicity and added 2 new functions.
The problem remains.
I'm not competent enough to identify why the library only allows 6 alarmRepeat(): events.

/*
  Timer relay control set up for 4 relay unit.
  Each relay is individually controlled.
*/

Thankyou ruilviana,

Appreciate you effort yes a bit of a tricky problem I’ll try read more on the documentation for the time function and see if there is a reason it won’t work properly. Damien.
