                                                          How Does This Work

This project takes the help of two online platforms, IFTTT and Adafruit MQTT . IFTTT stands for If This Then That, its a great platform on which we can merge two services by making an applet. In this, we need to provide one condition and one action. The Action will be performed whenever the particular condition will be satisfied.

With the help of IFTTT, I’m merging Google Assistant and Adafruit MQTT. The applet which I made is something like,

“If Google assistant listens to turn on fan, then send data 1 to fan feed of Adafruit MQTT broker.”

So this is one kind of applet which I made using IFTTT which combines my Google Assistant and Adafruit MQTT. Now how does Adafruit MQTT works? Basically, MQTT works on Broker Client Publish Subscribe method in which Clients are subscribed to one topic on the broker. Any data change in that topic will be reflected to all the devices connected to that same topic in that broker.

I Will Upload Video Tutorial Soon .
