IFTT if-sunrise-and-action

mit license Donate

IFTTT applet to use sunset/sunrise times as an additional if/then trigger for when to run an action. You can enable the original IFTTT applet here. Note that this is hardcoded for Dallas, TX.

Description

IFTTT made filter code a premium feature, so for the benefit of the IFTTT community, I am open sourcing the code for this applet.

You can easily adapt this template to limit any typical IFTTT action to happen between any hour and/or supported SunCalc time: ['sunrise', 'sunset', 'sunriseEnd', 'sunsetStart', 'dawn', 'dusk', 'nauticalDawn', 'nauticalDusk', 'nightEnd', 'night', 'goldenHourEnd', 'goldenHour']

After installation, two parts should be customized:

  1. GPS coordinates for your location

An adapted version of SunCalc is used to calculate sunset/sunrise times based on the GPS coordinates

// Customize for your geolocation
// Dallas, TX
var myLatitude = 32.8;
var myLongitude = -96.8;
  1. IFTTT-based code for when to skip the action. For example, in this code, the action is skipped during daylight hours.
var todaySunlight = <any>SunCalc.getTimes(triggerDate, myLatitude, myLongitude);

// Customize with getTimes properties, sunrise, dusk, etc.
if (triggerDate > todaySunlight.sunrise && triggerDate < todaySunlight.sunset) {
  WemoLightSwitch.attributeLsOnDiscrete.skip("Skipped during sunlight hours");
}
  1. If you want to use specific hours (i.e., not sunset/sunrise), here is an example of how that can be done. The filter.js code can be adapted to support any variation/combination you'd like.
var currentHour = Meta.currentUserTime.hour();
if (currentHour >= 20 || currentHour < 5 ) {
 // add action here
}

Notes

  • I experienced poor latency (up to 10 minutes in some cases) from IFTTT with this applet and moved on to other services
  • There is a small bug in the Suncalc library, affecting the time calculation in some instances having to do with daylight savings time.

See: mourner/suncalc#107
