[Owfs-developers] experiences with raspberry pi

[Nico B. <ni...@cu...>]

Hi all,

I’ve just lost a couple of days troubleshooting this…

I’ve been using a BeagleBone Black with a DS2482-800 for years without 
any issues to control my greenhouse. Recently, I decided to upgrade and 
switched to three DS2482-800s on a Raspberry Pi. At first, everything 
seemed fine—the devices and sensors were detected. However, from time to 
time, the DS2482-800 and the connected devices would disappear.

After some digging, I found the cause: I had also connected a SATA/USB 
disk to the Raspberry Pi for storage. Somehow, the disk interferes with 
the I²C interface. When running |i2cdetect -y -r 1|, the I²C addresses 
occasionally disappear.

Has anyone experienced something similar? It doesn’t seem to be a 1-Wire 
issue, but rather a Raspberry Pi flaw.

Thanks,
Nico
