Important points:
1. You don't need any Amazon echo device for this IoT Project.
2. You need to install ESP Rainmaker, Google Home, and Amazon Alexa IoT application on mobile.
3. You can control relays from any WiFi network if ESP32 is connected to WiFi.
4. Update the Preference URLs to install the ESP32 board version 2.0.3 as shown in the video.
5. To generate the QR code, press and hold the ESP32 BOOT button for 4 seconds.
6. Please watch the complete video, otherwise you may face some issues.
**Please take proper safety precautions while working with high voltages.

During the internet of things tutorial video, I explained all the steps to make this IoT-based home automation system, and how to connect Rainmaker with Google Assistant and Amazon Alexa app.
In this ESP32 project, you can control the relays without internet from the manual switches. ESP32 will automatically connect with the IoT cloud when the internet comes back.
If the ESP32 is connected with Wi-Fi, then you can control the relays from anywhere in the world with Alexa and Google Assistant. And you can also monitor the real-time feedback in the Amazon Alexa and Google Home IoT applications. So with this smart house project, you can convert any appliance to IoT devices and control them through the internet.

So, now you can just ask Google Assistant, "Hey Google, turn off lights", or "Alexa, turn on light". that's it.
