Instructables
Picture of Triggering IFTTT from Arduino using Lithouse

In this instructable, we will build a motion detector and trigger IFTTT events from that device.

You may create IFTTT recipes for receiving email if someone is inside the house or switching a Belkin WeMo when you walk into a room.

As the motion detector cannot directly contact IFTTT, we will use Lithouse as the broker.

Step 1: DIY Motion Detector

You will need the following components:

  • LED, Breadboard and some Wires.

Please connect these components as shown in the image.

  • Mount the Ethernet Shield on Arduino.
  • Connect the 5V and GND pin of the PIR to the respective heads of the Arduino Ethernet Shield.
  • Connect the PIR’s output pin to the pin #2 of the Ethernet Shield.
  • Connect the negative (short) leg of the LED to GND of the Shield.
  • Connect the positive (long) leg of the LED to one of the end of the 330 Ohm resistor.
  • Connect the other end of the 330 Ohm resistor to the pin #7 of the Shield.

Step 2: Register with Lithouse

Now, let us register the device with Lithouse:

  • Go to Devices tab and click the '+' button. A new window will show up.
  • Provide a meaningful name and description for your device group.
  • Then hit Add.

A more direct connection to IFTTT would be better. Lithouse should get their own channel on IFTTT and not rely on an email trigger.

Thanks for the feedback rmarler.

We just released Lithouse app in the App store (https://itunes.apple.com/app/id866665066). It is a one stop place for controlling all your smart home devices. This version supports Philips Hue and Belkin WeMo switch.

Please download, use and let us know your feedback.

Lithouse has some nice examples, but sending and email trigger to ifttt via smtp2go or some other simple email sending service is not difficult at all.

Thanks for the smtp2go reference. But, as you pointed out, Lithouse is more than IFTTT integration. We provide remote read and write access to DIY devices.
