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.
Had anyone successfully read the moisture sensors with a home brew one wire reader that would like to share how they do it? My Arduino detects an unknown one wire chip on the bus and I suspect the moisture sensor is connected to it but I don't know how to read it.
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.
