I am trying to use a UNO R4 to link to HomeKit via Homespan - when I try to run any of the examples I get the message: ERROR: HOMESPAN IS ONLY AVAILABLE FOR ESP32 MICROCONTROLLERS! as well as a missing file error (version.h). I'm new to Arduino but the UNOR4 spec says it uses ESP32 - I am confused …
