DIY IoT projects with no coding or soldering required!


Getting Started (2): Setup IFTTT

All of the projects on SimpleIOThings use an internet service called If This Then That (IFTTT). IFTTT executes an action, like sending an SMS or posting a Tweet, when an event takes place. Combinations of events and actions are called recipes, and you can do a lot of cool stuff with IFTTT recipes. For example, I use publically available recipes to automatically tweet my Facebook posts, change my phone wallpaper to the NASA Picture of the Day every morning and send me a smartphone notification if its going to rain tomorrow. Click here to setup an IFTTT account. You’ll need it later to execute actions from your IoT devices.

Using the Maker Channel

For SimpleIOThings projects we’re going to use IFTTT recipes that use the Maker Channel. The Maker Channel allows people to create recipes that interact with DIY devices. The DIY devices you can build using tutorials from SimpleIOThings will send messages over the internet to the IFTTT Maker Channel, which then triggers actions like phone calls and SMS messages. The Maker Channel can also send messages to DIY devices to trigger actions on the device as well.

Follow the link and connect to the IFTTT Maker Channel.


Once you connect to the Maker Channel, take note of your “Maker Key,” which is an alphanumeric code that identifies you and your DIY devices when they send web messages. You can jot it down somewhere, or you can always go back to to find it.

Using IFTTT Recipes & Organizing Events and Actions

Now that you’re connected to the Maker Channel, lets build some recipes that will trigger cool actions like smartphone notifications, SMS notifications, and phone calls. A greatfeature in IFTTT is the ability to share recipes. I’ve shared my recipe here, but just take a look before you sign up for it.

IFTTT Maker & SimpleIOThings Smartphone Notification Recipe

There are also other cool recipes that you can use. Using IFTTT, your devices can trigger phone calls, emails, and send SMS’s to your friends. Here are links to some more recipe I’ve shared for your convenience.

You can sign up for each recipe using the links. All you need to do is input an event name like “SmartButton” and clicking “Add.”

The reason why I asked you not to sign up for the IFTTT recipes just yet is because I want you to think about how you want to organize your event triggers  and recipes. Lets take a look at them in the next section.

Organizing Recipes 

Understanding how to organize your IFTTT Maker recipes will help you trigger the desired actions for a given event.

Example 1: Smart Button – Triggering One Action

One of the devices you can build on SimpleIOThings is the Wifi Smart Button. In the default case, I’ve assumed the user is going to use it to report a bad event (like security problems in a store) but it can really be used to send just about any message.

Lets say in this example you are using it to tell you’re significant other that you’re thinking about them. In a case like this, maybe you want to just send your significant other a quick SMS that says “Thinking of you. 😉 ~[Your Name].” You COULD send your partner an SMS, PLUS an email, and a phone call at the press of a button, but that would probably be overkill (depends on the message you’re trying to send I guess). To keep it classy, you could setup an event called “SmartButtonThinkingOfYou” in IFTTT, and have it trigger ONLY the smartphone notification with a sweet message. Later, once your program your smart button to trigger the “SmartButtonThinkingOfYou” event over Wifi, the following process should occur:

  1. You press the button.
  2. The Smart Button sends a message (via HTTPS protocol for you nerds out there ;] ) to IFTTT over Wifi with your Maker Channel Key and the Event Name (SmartButtonThinkingOfYou).
  3. IFTTT receives the message, finds your recipe, and sends a SMS to your partner’s phone carrier.
  4. Your partner receives an SMS, and smiles.

Example 2: Wifi Smoke Alarm Notifier – Triggering Multiple Actions

Pretty awesome right? However, there’s another project (Wifi Smoke Alarm Notifier) on SimpleIOThings that notifies you when your smoke detector goes off. When this device sends a message to IFTTT, you’d probably want an SMS, Smartphone Notification, Email, and Phone Call to tell you something might be wrong at your house. So for the Smoke Alarm Notifier, you’d probably want to setup an event called “SmokeAlarm” and sign it up for all 4 of those recipes. To do this, you’ll have to sign up for the SMS, Smartphone Notification, Email, and Phone Call recipes with the “SmokeAlarm” event, and then later program your Wifi Smoke Alarm Notifier device to send the “SmokeAlarm” event name when its triggered.  Once that’s done, when your device triggers it should result in the following process.

  1. Smoke Detector goes off.
  2. Wifi Smoke Alarm Notifier detects the noise from the Smoke Detector alarm.
  3. The Smoke Alarm Notifier sends a message to IFTTT over Wifi with your Maker Channel Key and the Event Name (SmokeAlarm).
  4. IFTTT receives the message, finds your recipe, and then:
    • Sends a Smartphone Notification
    • Sends a SMS.
    • Calls your phone with an automated message.
    • Emails you.

The bottom line is, you can setup your devices to tell IFTTT that an event occured, and depending on how you’ve configured your IFTTT recipes, the event can trigger a single action, or multiple actions. Some good planning and organization ahead of time will help you trigger the desired actions when an event occurs.

Testing Recipes 

Once you’ve signed up for your recipes you can test your them by going to the Maker Channel, then clicking “How to Trigger Events.” In the following page, enter the event name you created earlier, and click “Test It.” You should get a smartphone notification.

Download the IF App for Android & IOS

To receive smartphone notifications and monitor your IFTTT activity, you can download the IFTTT app on your smartphone. The app can also be used to manage your recipes and channels. You can download the “IF” app from the Android Play Store, or the Apple Itunes Store.

Okay! We’ve got some really nifty digital infrastructure setup for your projects. Now take a look at some of the easy to build Do-It-Yourself projects on SimpleIOThings, and use them to send messages, protect your stuff, and make your home safer.
