zu2 / wp6003 Goto Github PK

Hello, I'm trying to connect from my Raspberry Pi Zero with python 3.7.3. I seem to find the device and get a connected, but then get traceback errors ending in dbus.exceptions.DBusException: org.bluez.Error.Failed: No discovery started, Error in atexit._run_exitfuncs:
Can you give me any advice for troubleshooting?

I have previously connected to from this Pi to Mijatemp sensors with http://www.d0wn.com/using-bash-and-gatttool-to-get-readings-from-xiaomi-mijia-lywsd03mmc-temperature-humidity-sensor/ My M5stickC seems to be able to connect to the WP6003 without problems.
Thanks in advance.

First off, thank you for your work decoding the information. You saved me a lot of time!

But I have doubts regarding the calibration ('ad') command at startup.
As this happens indoors I now only get values around ~0.001 mg/m³.
I've put the sensor outside for recalibration and removed the 'calibration' code, and now it works better IMO.

Does your sensor work differently?

Thank you for your work.

Hi,

Thanks for the great work in decoding this device!

Has there been a change in the latest version of the app (v. 1.2.1 on iOS). Previously I got consistent CO2 reading between App and the python script of this repository. Now I don't anymore. Anyone else observing the same?

Example: 539 ppm with python script, 417 with app.
