Vc mexeu apenas no arquivo BrewManiac.cpp?
Eu sou bem ruim de programação, já tentei estudar oq modificar pra utilizar o MAX31685 mas não consegui entender o código pra saber como alterar os sensores.
Também não sou bom em programar, mas a gente se ajuda powh.
Eu alterei sim o BrewManiac.cpp e coloquei um #define UseMAX6675 true||false no config.h pois se eu quiser usar o DS18B20 ou MAX6675. Ajustei os pinos pra usar a interface SPI na Wemos e realoquei para usar na PCF8574 a bomb e heat e sensor level.
