The server is up here, but it's password-protected and the ESP32 is not connected right now.
- ESP32 uses a photoresistor to detect light flashes on an energy meter
- Sends a timestamp over TCP+TLS to the server every time
- NGINX handles TLS and forwards
- Server saves timestamps and builds up indexes in files
- Server streams live timestamps and responds to requests from frontend via application-level protocol over websockets
- NGINX handles HTTPS and forwards
- The API and indexes for viewing arbitrary graphs is implemented in the backend but only viewing live data was finished being implemented in the frontend
