Another Kind of Compile Warning

Hi first of all I'm sorry for my english! I have a ESP 32S board and the three examples in the your library don't work and give me a compile error:

I2C scanner give me the address 0x23.

I have tried the same sketch on an ESP8266 board and the sensor work great!

Please, can you help me?

cc1plus: some warnings being treated as errors ignore warnings and don't treat them as error. Or put a default: break; in line 174

Great! I have change the line and Arduino IDE have compiled the sketch! Resolved the problem Thank you so much!

Seems resolved now.
