Hi team, my sds011 sensor has worked for some weeks in the past but currently it does not work anymore with firmware NRZ-2024-135. I have checked to flash the esp-8266 with the SDS011 example SW from the Arduino IDE and with this SW the sensor works like a charm.
Back to the “airrohr” SW the sensor refuses to work (no data available in the device sensor status view). The BME280 instead works correctly.
Here is the output of the debug info (minicom):
