Hi RainerS,

Could you give further feedback? Thanks.

Hi, Sorry was quite busy lately.

I am located in Germany Stuttgart Area near Renningen/Boeblingen

FYI: The replaced sensor is still running fine after ~3 Month now. Will update if it goes bad.

I can still offer to send/give the broken sensor to you.

Hi RainerS,

I located in China.

As the HSMI document description, user should avoid to use the sensor in below chemicals environment which can damage the sensor permanently.

Also, as our previous experience, 'the sensor communication is ok and at same time the sensor performance is not good', maybe caused by contamination.

You can continue to observe replaced sensor, update if it is abnormal.

By the way, where did you buy BME280?
