I'm using owfs to integrate 1-wire temperature sensors into a comprehensive system to monitor a fleet of HVAC systems for my lab, datacenter, power plant and IT server room. Very cool!
Owfs creates a directory tree populated with files containing the variables from my 1-wire network. It was going to cost $2500 to monitor a couple dozen temperature points using an SNMP based temperature sensor system, but by choosing 1-wire and owfs, I have the sensor cost down below $100 for 2 dozen sensors.
To integrate with zabbix, I only have to tell zabbix to read the appropriate temperature file for the particular probe I'm monitoring.
I'm also using the ibuttonlink.com LinkHub-e 1-wire hub to allow me to combine 4 different 1-wire busses into one network. Each network segment can be up to 1000 feet long, and the number of sensors I can support is inversely proportional to the length of the network. Each device reduces the maximum length of the network by about half a meter.
1-wire has changed the way I think about building sensor networks. Owfs has simplified the process of integrating 1-wire designs into working applications. Add that to my favorite network management system, Zabbix... It doesn't get much better than that!
