**With this IoT project I can control all 4 relays manually with switches. But as I have used the free Sinric Pro account, so I can control 3 devices with Google Assistant and Alexa. To control the fourth device, you have to purchase 1 device in Sinric Pro.
**You don't need any Alexa devices like Echo Dot or Google Home Mini. You can just use Google Home App and Amazon Alexa App for this smart home system.
**If the ESP32 is not connected with Wi-Fi, then you may face some delay while controlling the relays from switches.
Download Code for this ESP32 smart house automation project from the following article. https://iotcircuithub.com/iot-based-projects-using-esp32/
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. I have made this Google Assistant control smart home system without IFTTT. If the ESP32 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.
