Example Applets using queries and filter code

Applet: IF you complete a new activity on Strava → THEN Send a notification

This Applet triggers whenever you complete a new activity on Strava. If so, a notification will be sent through the IFTTT app. But what if you don't want notifications on a weekend day? Or, what if it was rainy out and you still got your workout in? Congratulate yourself for training in unfavorable weather. Adding queries and filter code to this Applet will help you do that

Here's how you can set up the Applet:

Trigger service: Strava

Trigger: New activity by you

Query service: Weather Underground

Query: Two day forecast

Action service: Notifications

Action: Send a notification from the IFTTT app

Filter code:

// Filter code that demonstrates Meta.currentUserTime
// and logic to skip actions on weekends
// 0 is for Sunday and 6 is for Saturday

let currentDay = Meta.currentUserTime.day();
let currentCondition = Weather.twoDayForecast[0].Condition;

if (currentDay == 0 || currentDay == 6) {
  IfNotifications.sendNotification.skip();
}

else if (currentCondition == "Rainy") {
  IfNotifications.sendNotification.setMessage("Nice work getting your workout in on a rainy day");
}

Applet: Turn on my entryway lights based on outside brightness

To prevent turning on lights when it is light outside, we can make use of a query and filter code that will check for the brightness using the Tempest Weather System.

Trigger service: SmartThings

Trigger: Unlocked

Query service: Tempest Weather System
Query: History of observations
 

Action service: SmartThings
Action: Switch on 

Filter code:

let aboveThreshold = 100;
let currentLum = Number(Weatherflow.historyOfObservations[0].Brightness);

let time_unlocked = moment(SmartthingsV2.unlockedSmartthings.UnlockedAt,'MMMM D, YYYY at h:mmA').format("HH:mm");

var msg = 'Door unlocked at ' + time_unlocked + ' and it is currently ' + currentLum + 'lum above the ' + aboveThreshold + 'lum threshold.';

if (currentLum > aboveThreshold){
    SmartthingsV2.turnOnSmartthings.skip(msg)
}

Applet: IF you start traveling to your vacation home →THEN heat some water for your stay

When you have plans to spend your weekend at your cabin, you want the heater turned on before you arrive. This Applet, along with the Google Calendar Query and the filter code, will check whether you have an event with the keyword "Weekend at the Cabin" when you arrive near your cabin. If it does, the heater will turn on

Trigger service: Location

Trigger: You enter an area

Query service: Google Calendar

Query: Search events (set Query to “Weekend at the Cabin”)

Action service: WeMo Smart Plug

Action: Turn On

Filter code:

// locationDate will fetch the moment.js date object for the location trigger
// calendarDate will fetch the moment.js date object for the Google Calendar query

let locationDate = new Date(Location.enterRegionLocation.OccurredAt);
let calendarDate = new Date(GoogleCalendar.searchEvents[0].Start);

// The following if statement checks if the date and the month when you enter 
// the location matches the date and the month are the same. If they are the same, 
// then the action should run.

if (locationDate.getDate !== calendarDate.getDate && locationDate.getMonth !== calendarDate.getMonth) {
    WemoSwitch.attributeSocketOnDiscrete.skip();
}

Applet: IF tomorrow's forecast is clear → THEN schedule a long run

This Applet checks tomorrow’s weather then adds a “Go for a run” event to your calendar depending on the forecast. If it’s going to be sunny, you’re signed up for the long run. Otherwise, make it quick. Either way, you get a notification the day before as a heads up.

Trigger service: Date and Time

Trigger: Every day at

Query service: Weather Underground

Query: Two day forecast

Action service: Google Calendar

Action: Quick add event

Action service: Notifications

Action: Send a rich notification from the IFTTT app

Filter code:

if (Weather.twoDayForecast[1].Condition == "Sunny") {
  var length_of_run_in_minutes = "90"
  var length_of_run_in_words = "long"
} else {
  var length_of_run_in_minutes = "60"
  var length_of_run_in_words = "short"
}

GoogleCalendar.quickAddEvent.setQuickAdd(`8am tomorrow Go for a run ${length_of_run_in_minutes} minutes`)

IfNotifications.sendRichNotification.setTitle(
  `You're going for a ${length_of_run_in_words} run tomorrow`
)

IfNotifications.sendRichNotification.setMessage(
  `It's going to be ${Weather.twoDayForecast[1].Condition.toLowerCase()} with a high of ${Weather.twoDayForecast[1].HighTempFahrenheit}° F`
)

IfNotifications.sendRichNotification.setLinkUrl(
  Weather.twoDayForecast[1].ForecastUrl
)

IfNotifications.sendRichNotification.setImageUrl(
  Weather.twoDayForecast[1].TodaysConditionImageUrl
)

Applet: IF there's a new post on Reddit → THEN post a tweet with an image
 

This Applet posts a tweet with an image from a specified X (Twitter) account and skips tweeting if there's no image on the Reddit post.
 

Trigger service: reddit
Trigger: New hot post in subreddit

Action service: Twitter
Action: Post a tweet with image

Filter code:

let redditImageURL = Reddit.newHotPostInSubreddit.ImageURL;
let noImageURL = `https://ifttt.com/images/no_image_card.png`;

if (redditImageURL == noImageURL) {
  Twitter.postNewTweetWithImage.skip(`No image URL present`);
}
