Trying to register a new SDS011 sensor but it is already registered

FAQ

Hello I am trying to register a new sensor as far as I understand I get the sensor this way:

Then I tried with this recommendation by GPT:

response = b'\xaa\xc0\x86\x01\x16\x03\x71\x77\x88\xab'

# Extract the device ID bytes
device_id_bytes = response[6:8]

# Convert to hexadecimal
device_id_hex = device_id_bytes.hex().upper()
print(f"Device ID (Hex): {device_id_hex}")

# Convert to decimal
device_id_decimal = int.from_bytes(device_id_bytes, byteorder='big')
print(f"Device ID (Decimal): {device_id_decimal}")

and got a matching HEX from the ID of the sticker on the part but I still get:

" This sensor ID is already registered."

This is the ID in HEX and Decimal that I get:

root@raspberrypi:/home/ubuntu/pm2-sensor# python3 test.py
Device ID (Hex): 7177
Device ID (Decimal): 29047

Please let me know if this is the ID or I am doing something wrong.

We don’t need the id of the SDS011. What system do you want to use, esp8266 or raspberry or esp32?

I have a raspberry with the SDS011 sensor

Then you should use the serial of the raspberry cpu. This is normally listed in /proc/cpuinfo .

Thank you! Sensor registered and will write up the integration to send some “clean” data :smiley:

Hallo Zusammen, ich habe ein Sensor Community" Sensor.community KIT (SDS011/BME280)" gekauft. Ich habe Sensor angeschlossen. Alles funktioniert bis Sensor registieren möchte. Sensoren senden die Daten zu Web, aber ich kann sensor nicht registrieren, weil schon regiostriet als warnung steht. Wie kann ich dieses problem umgehen?
Sensor ID:
esp8266-13677651

Viele GrĂĽĂźe

Hello! I tried to register my sensor, but it was not visible on the map. Than I tried to register again, but the system writes the id is alredy registered.
What should I do?
Thank

Hello @ ricki-z, I have the same issue with the sensor id: 4890898

I’ve deleted my sensor from the system because of the wrong configuration. I want to register it again and now I getting an error: This sensor ID is already registered.

Can you help me please?

Why deleting when one has just to change the configuration ? I will never understand…

Hi, I tried to change the configuration ( working via mobile phone ) but I was missing the functionality to add sensor and change type of NODE… I decided to delete configuration and add it again. I’m wondering that delete works but it keep the NODE id in the database… It’s bug? Can somebody restore my id? I want to connect a new sensor into the community and it’s blocking issue for me…

@ricki-z will do soon.

@jgerek There was a warning as you deleted the registration that you won’t be able to register the chipID again …
We may need some of the information in the registration some days after deletion (i.e. saving data to our archive). So we can’t delete it completely directly.
