Hi, I've tried now with a little help from my friend... ;-) to fix it. I have made a pull request for it.
Have not been able to test it myself yet.

Decription:
The Adafruit library moved P0–P3 from module-level exports into the class itself in a recent update. The fix:
ADS11.P0 → ADS11.ADS1115.P0 (lines 251–254)
ADS10.P0 → ADS10.ADS1015.P0 (lines 264–267)
Both ADS1115 and ADS1015 are fixed in openplotterI2cRead.py.

hello Leif

I modified /usr/lib/python3/dist-packages/openplotterI2c/openplotterI2cRead.py as indicated

unfortunately that doesn't fix the error
I still get the same error

the I2C gui lists the inputs as A0...3

if I rename to
ADS11.ADS1115.A0
same error

after I rename to ADS11.ADS1115.0
error gets worse :

↳service not running

Hi, yes, later last evening I managed to work locally in my Openplotter with the help of Claude, and now my code is working. I will make a new pull request and also try to publish the file here. I can now see A0-A4 as it should be. It was changes like above for the names and also a small change for the GUI in the same file.

/Leif

Leif
please, please, please give me some detailed info about how to solve this.
I am banging my head since some month as I need voltage readings to switch off automated processes to run openplotter 24/7

/Wolfgang

Finally :-). Now I managed to have my openplotter working with the updated code. Also managed to create a pull request for it:
https://github.com/openplotter/openplotter-i2c/pull/16

There you have all information about how to clean config, and updated code in :
https://github.com/LeifYKlasson/openplot...I2cRead.py

Now just waiting to have it confirmed and merged in...
