I use the temp08 made by http://www.midondesign.com/

Quick delivery to the UK, good build quality / support

I connect into homeseer to monitor temps in various rooms script provided

I mounted the DS18S20 on the back of my alarm PIR's and used spare cores to
connect back to unit.

I know some on the list have/do use iButtons so I thought this would be the
best place to ask.

I've been reading about iButtons and their usage recently and I would
really
love to use them around the home. My first project would be to use an
iButton on a keyfob for identification just as you enter the house. The
iButton would be used to retrieve relevant information for that person such
as how many emails are waiting for them, outstanding appointments/tasks
e.t.c. What is the best iButton for this? A DS1990A?

My second use would be for temperature monitoring. I'm in the process of
installing CAT5e to the bedrooms for ip camera's and would love to add temp
monitoring as I am doing it. Am I right in guessing that I need the DS1920
for this?

Also where do I get the hardware from? The US or is there somewhere here in
the UK that I can use?

Any help would be appreciated as I'm an iButton virgin ;)

Thanks,
Jamie.
