Today an update of IFTTT capabilities for interacting with Nest-Protect sensor devices in the home. IFTTT lets you add layers of simple intelligence to the smart home (or business) based on streams of information from the an IOT. As a simple example you could have all the lights in a home blink when Smoke or Carbon Monoxide is detected by a sensor. Or notifications sent to an address.
Plan to experiment with these in our Smart Home. More examples of this kind here. It is recommended to understand the capabilities of IFTTT. I have a number of applets in operation.
