During the ESP Rainmaker tutorial video, I covered the following topics:
02:02 Control relays with Google Assistant & Alexa using ESP32.
02:30 Control relays manually with IR remote & switches.
03:38 Monitor DHT11 Sensor & LDR values on ESP RainMaker.
04:11 Add automation in ESP RainMaker.
05:05 Circuit diagram of ESP32 smart home project.
05:56 Source codes for the ESP32 IoT Project.
09:12 Update WiFi details through OTA with the Rainmaker app.
10:18 Connect Amazon Alexa with the ESP Rainmaker app.
11:03 Connect Google Home with the ESP Rainmaker app.
Required Components for the ESP32 internet of things project.

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. R receiver sensor must have a metallic casing. Otherwise, you may face issues while trying to get the Hex code.
7. 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 ESP32 home automation system, and how to connect Rainmaker with Google Home and Amazon Alexa app.
In this ESP32 project, you can control the relays without internet from the IR remote & switches. ESP32 will automatically connect with the IoT cloud when the internet comes back.
You can also add schedule in ESP Rainmaker app to control the relays automatically.
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 and sensor reading 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.
