The values from BME280 get strange even after 24 h after reset -144.1 c probably lowest temp

Placed outdoors pipebend style has been running a long time with 2020 dec fw and i changed from previous temp/rh sensor a month and a half ago. BME280 Shows 581.1 hp instead of 1007 hPa real pressure. works again after reboot then goes down tu the bottom.

This usually indicates a problem with the wiring (loose connections or corrosion). It could also be an issue with the power supply.

I had this problem a while back and it disappeared after replacing the Dupont-cables with fresh ones.

I made a visit out to my balcony and checked the sensor and eliminator all ok except that the tube had rotated a bit so it invited some rainwater ... ,-[ secured it in the right position and it worked as before. Still wondering about the issue with the quick change to -144 i have one indoors without outdoor problems. But when i use a call from domoticz to read data.json it seems to disturb the registers in the lolin v3 sometimes.
