HI can you detail what board you are using? along side the reef-pi version and little but of your setup. reef-pi only uses the opensource ph board driver or ezo driver.

What do you mean with "the opensource ph board driver" ? How can i check that ?

For information, my "simpletest.py" works ONLY with python3 and not with python. Maybe it's the problem ??? But I dont' kno how to fix it.

Thank you.

The pH board driver is compatible with ADS1119, so it will not work with ADS1115. We have a separate issue to add support for ADS1015/ADS1115. I expect to begin working on that feature in June.

I recommend closing this issue since it is not currently supported.

Ok, thank's for your quick answer. Can i help you ? I can try to implement it if you explain me quickly how and where code this. Did you have a developper guide ? June is perfect if it's longer to explain to me than to developper by yourself ;-).

You are welcome to give it a shot. I was planning to start on it this weekend, after I finish adding a few more light profiles to the UI.

We have a developer guide at https://reef-pi.github.io/additional-documentation/development/. It does not address driver development directly, but you would need to be able to build and run reef-pi in order to confirm the driver works. We also have a slack channel for more realtime dev discussion.

Developing the driver would require implementing the Driver, DriverFactory, AnalogInputDriver, and AnalogInputPin interfaces. You could use the pH-board driver as a sample.
