Hi,
Can anyone advise the code changes need to enable 2 button use on the ESP32 board? The instructions in the Docs is for the D1 Pro board and the pin assignments are different.

I tried fiddling in Config.h and different pin combinations to no result.

Thanks
Glen

The only pins available of ESP8266 are D0 and D2 that should be left open when boot. That's why I implemented two buttons. The operation is awkward in my experience. ESP32 has more than enough pins for rotary encoder, so rotary encoder is the only supported input device.

OK.
I asked as I was retrofitting an ESP32 to a previous brewpiless build which used an ESP8266.
