From the project
Open Source Area Timer for combat robotics
An open-source, ESP32-based event and match timer platform featuring wireless remote integration, with web interface.
Note: The local AP interface is identical to the network interface. If no external Wi-Fi network is available at your venue, you can run the timer in this standalone mode completely offline.
4. Station Mode (Optional): To connect the timer to an existing venue Wi-Fi network, use the configuration section at the bottom of the webpage to save your local SSID and Password.
