simple 1-wire contact closure

[politics123]

Hi all --


Is there a 1-wire solution for monitoring contact closures? (not a counter, just something that can tell whether a door is open or not). I have a punch of 1-wire temperature sensors in my network, but I'd like to track (along with the temperature data) whether the windows/doors are open.

Thanks!

Both HB and Midon have devices you could use on your 1-wire network.
