This project is a Flask-based web application designed for managing and monitoring network devices, including lab equipment and SATCOM systems. The application provides real-time access to device information, control over relay states, live video feeds from RTSP cameras, and network monitoring via LibreNMS.
Power Controls: Users can remotely control the state of relays, which are critical for managing various configurations within the networked environment. New devices are automatically discovered and added.
Live Video Feeds: The application supports live streaming of video from RTSP cameras, providing users with a visual feed of SATCOM antennas.
Network Monitoring: Integrated with LibreNMS, the application monitors the network of the lab environment. It tracks device status, internet connectivity, and SNMP poll results. New devices on the network are automatically discovered and added.
IP Subnet Calculator: Users can calculate subnet information based on IP address and subnet mask represented in CIDR notation.

## Dependencies
The required dependencies for this project are listed in the requirements.txt file. Install them using:
pip install -r requirements.txt
## Usage
1. Start the Flask application:
python app.py
2. Access the web interface by navigating to 'http://<your_server_ip>:8000' in your web browser.
## Making Changes
To make changes, connect to the server with an FTP client such as FileZilla and transfer the updated files to the application directory. Then, perform the following commands in the server shell:
sudo systemctl daemon-reload
sudo systemctl restart labwebapp.service
To check the status, use the following command:
sudo systemctl status labwebapp.service
