If the door is opened send me a notification.

Connect

Hook up a door sensor (like https://www.adafruit.com/products/375) to a device that notifies a feed with its value. When the door is opened it will notify your phone!

This Trigger fires anytime it validates the data that you send to your feed. Example: If Feed Temperature > 80, fire Trigger.

This action will send a notification to your devices from the IFTTT app.
