ESP32 based IoT project using CADIO, Android App, Google Assistant & Alexa - No Coding

We will utilize CADIO firmware and the CADIO mobile app to develop this project. For both the ESP8266 and the ESP32 development boards, CADIO firmware is available. We can communicate with our IOT devices using local networks and the internet, from anywhere globally by using the CADIO app. We will also be able to access our IOT device by connecting Amazon Alexa and Google Home to the CADIO account.

Required Components for the ESP32 Internet of Things project.
1. ESP32 (ESP-WROOM-32)
2. 4-channel 5V SPDT Relay Module.
3. 4 AC light bulbs
**Please take proper safety precautions while working with high voltage.

Key points:
1. To obtain the CADIO firmware, visit the CADIO official website at egycad.com
2. Download ESP Flash Tools in order to install firmware into our ESP microcontroller.
3. Sometimes, we may need to press the Boot button on the ESP32 board to start uploading.
4. If you want to alter anything in the info file, you must erase the flash and re-flash the firmware using the ESP Flash Download Tools.
5. by pressing the config button for 3 seconds, the device will generate a configuration WiFi network to which you can connect and alter the unit configuration.

I went over every step of how to create an IoT-based home automation system with an ESP32 and Cadio in this tutorial video. This IoT platform is the easiest for beginners to use because it doesn't require any coding knowledge. To automatically control the relays, you can also set a timer or make a schedule via the Cadio app.
