Temperature shows -141.63 °C

Hi, been using the sensor for a while now, but for a few weeks the temperature shows -141.63 °C constantly. A reboot didn’t help. Any suggestions? Todays actual temp is somewhere around 4-6°C.

(SDS011 & BME280)

Solved: A combination of rebooting again and unplugging the power supply seems to have helped finally. So far I only tried one or the other, never both.

Look like a bit shifting because of connections or insufficient power supply.
