In this Internet of Things project, I have shown, how to make Google Assistant ESP32 based home automation using Arduino IoT Cloud. Also control relays with IR remote and manual switches and monitor the room temperature from DHT11 sensor. I have used all the FREE tools for this IoT-based home automation system.

During the Arduino IoT cloud tutorial video, I have explained all the steps to make this ESP32 smart home system with Arduino IoT Cloud to control the home appliances with and without the internet. I have also shown how to connect Google Home with Arduino Cloud to control the relays with voice commands. If the ESP32 connected with Wi-Fi, then you can control the relays from anywhere in the world with the Arduino IoT Cloud mobile app and Google Home. And if there is no internet, still you can control the relays manually with IR remote and switches. 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 say "Hey Google, turn on Light" to control the home appliances.
