Our smarthome system employs IoT devices, with the ESP32 serving as the control hub. Communication between the ESP32 and the server is facilitated by the MQTT protocol, while NodeJS is used to develop the server and MongoDB is employed to store data. A web client is built to oversee device control and data analysis, with REST API used for server-to-web-client communication, complemented by WebSockets for real-time communication.
In addition, we try to use great platform Sinric Pro - a cloud service that enables voice control of devices. Specifically, we use Sinric Pro to control up to 3 devices and , employing either Alexa or Google Assistant for device control.
