Snow came in my balcony without realizing it!. It came into my attention after watching the temperature data fro the two sensors (SE001 and SE002). I sow on Grafana that temperature1, humidity, barometric had no values (that is the MBE280 module) . When in balcony SE001 was covered with light snow. Still working but not the BM280 module...Get it out to repair the damage.

SEE001 readings
 temperature1, humidity (BME28 module) not working
temperature2 (DS18B20 external waterproof) working fine

SEE002 readings
temperature1 (BME28 module) working fine
temperature2 (DS18B20 external waterproof) working fine
