BME280 accuracy

[Sadsyndrome]

Hello. I appreciate that temp accuracy is +- 1degreeC but I have seen info that shows this to be worst case.

Do you think that the attached graph that shows temp readings from 2 seperate BME280 breakout boards (via PicoW micro python with default BME settings every 10 mins) is normal?

The graph also has an average of the 2 readings in yellow. The boards are next to each other with no external heat source nearby.I have a portable Hive mini thermostat also next to the 2 BME280 and this shows reading somewhere in between the 2 BME readings. My goal was to check how accurate the Hive stat was, but this is proving difficult at the moment:)

Hi Sadsyndrome,

Could we know some information about your test:
Is there an outer shell on the circuit board?
What is the testing environment like? Sensor placement, surrounding environment, etc.
