@Deedee What exactly doesn’t work? (If you hope that the position on our map is updated automatically, this won’t work by system design. We only support devices with fixed positions,)

I don’t see my SEN55 show up on the map. The location parameters have been set manually.

Is there a debug on USB/Serial.
Does the SEN55 send to PIN 1 (SPS30 emulate)

Trying to send to pin 1 now.
There is no debug on this firmware version. Using firmware 5.12 eng from Helmut Bitter.

I have checked firmware 5.12 and has pin 16
On debug level 6 USB/Serial ( NRZ-2020-133/NL)

Hi, I recently bought the SEN 54 and I have no idea where to start. I want to try it on a Raspberry Pi Pico 2 W or on an ESP8266 in MicroPython. Does anyone have an idea where I can do it or has anyone already tried it? Thanks.

Hello Bert, do you still have the SEN54 or what do you use for SEN54 works ?
Thanks !

Здравствуйте! Помогите собрать сенсор контроля воздуха, живем возле промышленной зоны. Формальдегид, диоксид азота и серы

i made a case and put the SEN55 outside once again, after months..
first of all, i noticed that some values are always the same.
for example:
```auto
SEN55 PM2.5 14.0 µg/m³
SEN55 PM4 14.0 µg/m³
SEN55 PM10 14.0 µg/m³
```
i left it several hours, logging to influx, and the results are the same as you see..
the sensor is not faulty, for sure, its brand new..
this happens to all of you using SEN55 ?

Which firmware is it?
Maybe same bits each time for the calculation of the value.
But the SPS30 also did that sometimes.

Firmware version: FWL-2025-01-P5/EN (Mar 17 2025)

i think there was a beta firmware supporting SEN55.
you know where to find it and how to flash it ?

This is a problem of the Sensirion sensors. (SPS30 ,SEN5X and SEN6X)
I have exact this problem with the SPS30 and the old SC firmware.
In NL [Samen Meten - Dataportaal](https://samenmeten.rivm.nl/dataportaal/) they have removed all the SPS30 PM10 values
Note from the Sensirion manual

so, what do i keep from these ?
and the values of p0 only differs from others..
