37. Scenario Creation
• Basically possible through designated controlling apps/ software i.e.
Google Home, Amazon Alexa etc.
• Other 3rd Party app is also available. i.e.: IFTTT (If This Then That)
22-Dec-21 All resources from Internet| Non-Commerical Usage 37

38. If This Then That (IFTTT)
• One of the most powerful ways of making disparate smart home
devices work together is to open an IFTTT account. The acronym
stands for “If This Then That,” a service in which an action by one
device (or service) can trigger an action on one or more other devices
or services.
• IFTTT is very much like having a smart home hub in the cloud, and it’s
widely supported—and not just by smart home products and
services.
