No Humidity Data? about bme280

[bradyjoh]

It looks like in the BME280.h file there is no return set for float hum(); so could this be an issue, where the BME280 library is actually not reading the data?

You probably have a BMP280. They don't do humidity. Christian

I am relatively confident have a BME280, as that was the part I ordered. I guess they could have sent me a BMP, but that's shady :(

There's no way to test, is there?

You can read the chip id: chipID().

 static const uint8_t BME_ID          = 0x60;
 static const uint8_t BMP_ID          = 0x58;

A lot of the manufactures refer to the BMP sensors as BME/P 280.
