Hi Nico,
I have been running a 1-wire system on a Raspberry Pi with a Sheepwalk
Electronics RPI3 adapter for many years. I believe the adapter uses the
DS2482-800.
The 1-wire network lock up occasionally and needs the +5v supply to the
adapter to be turned off and back on again. I understood from feedback
on this forum that it was an unavoidable 'feature' of 1-wire. I then
installed a second Pi which monitors the first and operates a relay to
cut the +5v for a few seconds. It is random but I guess every month or
so on average.
I don't know if that helps at all....
Cheers
Mick

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
