Hi,

I'm trying to get an si7021 that should be the same as the sh21 to get correct on my pi on the i2c bus.

On my esp8266 I simply get steps of 0.1 degrees, so 20.0 20.1 etc.

On my pi, with the I2C_SHT21 module i get only steps of 0.7 degrees. so 20.0 than it jumps to 20.7 and 21.4 etc.

Why is it on the pi not that?

regards Richard

I tried http://www.raspberrypiblog.de/wp-content/uploads/2013/11/Raspi-SHT21-V3_0_0.zip

and this one works with 0.1 steps. Bug in the i2c_sht21???
