Hi ,

I’ve setup my unit and the SDS 11 is working fine , but temp \ pressure sensor not working

Like here : [BME 280 not found](https://forum.sensor.community/t/bme-280-not-found/198) the unit is not found

I thought it might be this : [NodeMCU flashing additional info](https://forum.sensor.community/t/nodemcu-flashing-additional-info/966) so erased and reflash to the bme-280 latest firmware but still no avail

I have soldered all pins , I have a multi meter and have checked Continuity between the pins and the board to make sure solder is good , have measured 3.3 v across GND and VCC , tried different gnd and 3.3 rail
