Reading OPI Cables with and Arduino

I am interested in seeing if anyone has been able to successfully read OPI cables with an Arduino or other microcontroller. I found an old thread about it, and it looks like folks have been able to get the temperature and relative humidity.


The main question I have here is how can you get the addresses of the different sensors, and how do you know which level in the cable they are?

Thank you for your ideas. The subscriptions on these cables are just getting very high.

Why are analog capabilities necessary? With 1-wire everything is digital, even the temperature and humidity values you are reading.
