I want to start a waterpump every six days and run it for four minutes when ”vattningstimer” reaches zero. After the pump is stopped I also reset the timer which starts over again. Three messages are also sent for control purposes. I use CountDown which uses seconds so the reset value for the timer is 518 400 seconds (six days). However there is a delay of about 41 minutes when the pump starts again after six days. Can anyone explain why?
Also a basic question, are the set delay for the different action counted from when the timer reaches zero or are the different executed one by one with the delay time starting after the previous action is executed?
The timer restarts 6 minutes after the previous one ended. So the timer so be 6 days minus 6 minutes?
(Doesn’t explain the 42 minutes)
(Is an interval of 7 days an option? Because then can use a alarm. Or ‘it is 8:00’ and ‘today is a Saturday’)
Hi, no that’s not an option, I want a flexible timer working with any interval. Are you shure that the timer resets 6 minutes after the previous card i.e. 15 minutes after timer reaches zero and not 6 minutes after timer reaches zero? Neither explains the delay though.
Both notifications (efter 5 min, efter 7 min) are posted on the timeline 2 minutes apart. Not 7 minutes So the minutes are counted from the moment the timer ends. Therefore I think you should subtract 6 minutes form the timer. (Or remove ‘efter 6 min’)
(41 minutes on 6 days is 0,5%. Maybe the timer is just not very accurate?)
Hi again, thanks for your help. I did not note your observation that the notifications are two minutes apart, confirming that all programmed delays are counted from the trigger instruction ”timer reaches zero” 
. I guess the CountDown timer isn’t more accurate than this, perhaps not meant to be used as at ”day” or ”week” timer? I will shorten the timer setting and see what happens.
