Important points:
1. You don't need any Echo Devices for this project.
2. In FREE plan you can add maximum 3 devices in Sinric.
3. For LEDs or Active-High relay, no modifications required in the auto-generated code.
4. For NodeMCU, the Boot will fail if the D3 (GPIO-0) (switch-2) is connected with the ground during booting.
5. If you use Switch (latched) with NodeMCU, make sure the switch-2 is OFF during the ESP8266 Boot.
**Please take proper safety precautions while working with high voltages.
For this project, you don't need any custom design PCB.
During the internet of things tutorial video, I have explained all the steps to make this ESP32 home automation system with Sinric Pro to control the home appliances with Wi-Fi. Also explained the circuit diagram and how to configure Sinric Pro for ESP8266 and ESP32. If the ESP32 is connected with WiFi then you can control the relay from anywhere in the world from Google Home and Amazon Alexa app, otherwise you can use manual switch to control the appliances.
