Flashes the fan controller firmware directly from this page — no PlatformIO or cables beyond the USB one you're already using.
Plug the ESP32 into this computer via USB.
Click install, then pick the board's serial port in the browser prompt.
When flashing finishes, the page will offer to set up Wi-Fi — enter your network name and password there.
Once connected, check the on-screen IP address (or the serial log) and open it in a browser.
Your browser can't do this — use Chrome, Edge, or Opera on desktop.
This page needs to be served over HTTPS (or from localhost) for the browser to allow serial access.
Note: installing erases any fan names/speeds and Wi-Fi
credentials already saved on the board (you'll be asked to confirm).
For source, wiring, and the full REST API, see the
project repo.
