This smart intercom system connects a TV app, mobile app, and an ESP WiFi module to enable real-time communication across devices within a building or home network. The system is designed for seamless operation using local WiFi, without the need for internet connectivity.

Key Components:
TV App: Acts as the receiving station, usually installed on an Android TV or smart display device. It displays messages, announcements, or calls in real time.
Mobile App: Used to send text messages or announcements directly to the TV app.
ESP Module : This WiFi-enabled microcontroller connects to the same network and acts as a bridge, synchronising time and ensuring real-time data flow between the TV and mobile apps.
How It Works:
All components (TV, phone) connect to the same WiFi network.
The mobile app sends messages or voice commands, which are transmitted via the ESP module.
The ESP module ensures accurate, real-time communication, providing timestamped data and keeping the system synchronized.
The TV app receives and displays messages instantly, enabling efficient intercom functionality.

Features:
Real-time date/time using the ESP module as a sync hub.
No internet required.
Encrypted and secure local data transmission.
Ideal for buildings, homes, offices, or apartment complexes.
