Many people like automation and me too. This is the tutorial in which I'll be guiding you how you can control lights using Alexa or Google Assistant.
Why use MQTT and IFTTT?
The answer to this question is quite easy, We are using this because this is a very easy and reliable method to work with. I tried to use a WEMO switch emulation with Alexa Device but due to recent firmware updates Echo devices are not able to find or discover the ESP board with WEMO emulation. so this is the way that I found easy and reliable because by doing this way you can also control your lights from a phone, any browser, Alexa enabled devices, Google Assistant, Cortana and from any corner of the world where you can reach to the Internet.
What will you need?
- ESP8266 Development Board
- Relay Switches (I used 4-channel Relay Board)
- Jumper Wires
- Arduino IDE and some libraries
- USB power supply for ESP and Relay to operate
What do you need to do?
- First, install the Adafruit MQTT library into your Arduino IDE.
- Download code from my GitHub repository.
- Create an account on io.adafruit.com and ifttt.com
- Create feeds in your Adafruit dashboard and then link those feeds in IFTTT
- Change the code according to your needs.
- Complete the circuit of relays and the controller as shown in the image below
- change the key in the code received from Adafruit dashboard
- Upload your code to your controller
- Test if it is working correctly and check the serial output for debugging the problems
