Fun news:
Yes, Keg Cop is supported by BrewFlasher Web Edition!I just released my latest project - BrewFlasher Web Edition! Flash BrewPi-ESP8266 (amongst other projects!) to your controller, straight from your web browser.
This project took all the magic of BrewFlasher, and stuck it in a web app. Flash any ESP8266/ESP32 firmware supported by BrewFlasher, straight from your web browser. No downloads needed.
BrewFlasher Web Edition is available at: BrewFlasher Web Edition
The code is open source, and is available at GitHub.
Note - Due to the APIs required, BrewFlasher Web Edition only works in recent desktop versions of Google Chrome, Microsoft Edge, and Opera. If you don't use one of those browsers, try BrewFlasher desktop edition instead.
