BMP280 give wrong temp at below o
The BMP280 shows in the transition to frost a wrong temperature value. The measured value jumps nearly 2 degrees up.

I also had too high readings and I think that error is from continuous measurement in Bosch sensor so I set standby 1000ms (and some other settings) in this commit https://github.com/letscontrolit/ESPEas ... 25e985955a and my reading now are correct.c0ding4fun wrote:The BMP280 shows in the transition to frost a wrong temperature value.

I tested it on my BMP280 and on my BME280 they both show now values close to my reference ds18b20 (before that commit 1-2 degrees up).

sorry wrong reading... deleted my comment.
BME280 delivers below zero also false temperature value
With my outside temperature sensor on the chart is in the morning a jump at minus 2.1 degrees to zero and then again a jump at minus 2.1 degrees:
Could this be caused by an incorrect formula calculation from ESPEasy because I also correct the temperature measurement value with this formula:
