where in code is var "controlProtoco"l defined?

[mitchjs]

@PaulWieland , i grabbed the latest MAIN source, and i see this var is undefined
i know its a string... but odd that in the source its missing, as it wont build of course

thanks

I'd like to also be able to build the firmware to see if I can fix the issue where ratgdo stops responding to commands to open and close the door and has to be reflashed. @PaulWieland , is the webserver source for this build located anywhere on github?
