Sounds like all this should work.

The keypads/buzzers wouldn't be 1-wire (as far as I know).
The LCD screens could be 1-wire, if they are small text screens.

We hadn't put in a family-read (reading just one class for efficiency), but it
wouldn't be hard -- that's for the keyfob control. You'll still need to poll for
it. (Though I suppose you could only poll if there is an alarm present).

The DS2408 has a "latch" -- it triggers if the sensors hit a certain condition,
like a disconnect. You can then make the polling loop more efficient. Only the
triggered sensors would show. There is an "alarm" directory that only shows
devices that have triggered.

Finally, you can read owserver with multiple clients, PHP, webserver, shell
scripts, etc simultaneously. That would make sense -- separate display,
monitoring and control. You could even run your web client remotely, and reset
it remotely if you had sufficient security.

Subject: [Owfs-developers] RE: Help Designing a 1Wire system


hello, thanks for your input...
So will it be able to handle 100+ ports (divide by 8) approx 13 2408's? as
well as a couple of keypads/buzzers/lcd screens?

also how would i go about using a ibutton keyfob for user authorisation?
instead of using a key to reset/turn on/off the alarm i want to use a keyfox
with an ibutton in it. So it will just be touched to a reader then verified
against a valid user list and then  deactivate the alarm system..
I am looking at making it web manageable, with the php part of owfs is it
only a frontend to the owfs or can they not run at the same time, i am
wanting to build the system to run 24/7 and just use the web console as a
management/monitoring system, not actually using php to do the processing

thanks
