Yes, because each poll means a specific 1-wire command on the hardware.
Thus on each ds2409 coupler if both branches are in use (ie contain
Hi,
The phantom problem is resolved by adding the
w1_smem slave to the kernel as a module (after some modprobe no more
unregistred 01..3d's).
but still no reset pulse on the bus...when I modprobe my slave device, the
w1_family_register returns a 0, which means after reading the code
My current setup checks outdoor and greenhouse temp to determine
whether to turn on a 240VAC power switch to heat up (or cool down)
the greenhouse. owfs polls every 15 seconds?
owfs never poll on itself !
If owfs never polls itself, how does the cached directory structure get
updated? Maybe
you should read the directory, or cat the value if using owfs (filesystem)
to 'poll' the ow network

by itself, owfs does not actively poll the slaves. it only access the bus to
get the informations queried by the client application (ls, owread, ...)
1-wire is a slow bus on which many sensors (slave) may be attached.
Discovering every slaves connected and reading theirs state is a relatively
long
Thanks for all the replies, I have made some progress!!!
The problem was indeed caused by volt drop, the thing that confused me
was that as I said I have separate supplies for sensors and relays.
What was happening was that the relay circuit was causing the Gnd
connection at the far end to come

Hi everybody.
In the company which I'm working for, we use 1-wire for more than 18 months.
We use it in our server rooms, to monitor the temperature in it (and
send alerts when it's too hot) and we plan to monitor temperatures

put the new power supply with the onewire ground, ground the master ow

Hi folks,
Well I'm progressing well with my 1-Wire bus master over IP. I don't
have the bus locking in place yet but the code is in for owfs to use the
bus master and things work.
Perhaps I am missing the obvious, or you're talking about
