What’s new: A creative maker has developed a Wi-Fi mood light that visualizes network data through dynamic light patterns using an ESP32 microcontroller. The device operates in promiscuous mode to detect nearby network activity without needing access credentials, providing real-time visual feedback on Wi-Fi channel usage, signal strength, and device connections. It features multiple display modes, including channel scanning, LAN traffic visualization, and an intrusion alert mode that flashes red when a new device connects to the network.
Who’s affected
Network administrators and users of Wi-Fi networks may find this tool useful for monitoring network activity and performance. The device can help identify congestion and potential security issues by visualizing real-time data.
What to do
- Consider building the Wi-Fi mood light for enhanced network monitoring and visualization. The project is open-source, with available design files and code for customization.
- Utilize the device’s features to optimize Wi-Fi channel usage and monitor for unauthorized device connections.
