Check for a particular Time to fire an event

frlobo · May 21, 2017, 11:18pm

Hi,

I am looking for the best way to trigger an event at a particular time of day or even at a particular day. Say every Monday at 8pm. Is there a preferred way to do this?

My thoughts are with Time.day() == the day I want to fire, Time.hour() == etc…

I think @BulldogLowell has had a library for that and there also is this

@frlobo, as @scruff mentioned have a look at Timer2 in this example:

BulldogLowell/DailyTimerSpark/blob/master/firmware/examples/SimpleExample.ino

/*
DailyTimer.h Library
BulldogLowell@gmail.com
April, 2016
** Library provides tools to set daily timers for control of devices such as lamps, appliances, etc. Developed primarilary for houshold presence simulation.
** Allows for setting ON and OFF times, days of the week (i.e. weekends, weekdays, Fridays) and the use of random on/off times using this Constructor:
   DailyTimer myTimer( START_HOUR, START_MINUTE, END_HOUR, END_MINUTE, DAYS_OF_WEEK, RANDOM or FIXED)

** Timers may bridge midnight, simply enter times accordingly:
   DailyTimer myTimer( 18, 30,  1, 45, WEEKENDS, FIXED);  // starts at 6:30pm Saturdays and Sundays and ends at 1:45am the next day.

** Automatically sets correct timer state on powerup, using isActive() in loop(), see example below.
** Random start and/or end times using this member function:
   myTimer.setRandomOffset(30, RANDOM_START);  //  Can be RANDOM_START, RANDOM_END, or both (RANDOM)  default random offfset is 15min

** Random days of week using this member function:
   myTimer.setRandomDays(4); // will select four days of the week, randomly.  Useful to run this member function once a week, for example.

** Select custom days of the week using this member function:
   myTimer.setDaysActive(0b10101010);  // e.g.Sunday, Tuesday, Thursday and Saturday Note: Days in this order:  0bSMTWTFS0 <- LSB is zero

@ScruffR, I’m in the process of completely refactoring this lib to use start/end callbacks. the original was just me converting my original from Arduino, I’ve re-shaped its use.

The Arduino is already updated, I still need to finish some simple constructors, refactor for Particle’s time library and put into new library format.

You could use IFTTT to ping your device using the date&time module. That’s an extra service to configure, but then you can easily update the timing if necessary without modifying your firmware.

Thank you everyone for your help!

@BulldogLowell will give it a shot! Thanks
