Cacti templates for OW-Server

The OW-Server is an interface between 1wire protocol and IP (through ethernet of wifi for the wifi version of the product). It has 3 1wire channels which support 8 devices each for a total of 24 devices. The OW-Server is sold by Embedded Data System.

Embedded data systems sell a more advanced 1wire to ethernet interface : the HA7net. The HA7net supports more devices but the OW-Server has an advantage over the HA7net : it supports SNMP.

With SNMP it is easy to create RRD graphs from the OW-Server. However I did not find templates for my favorite graphing/monitoring tool : cacti. So I created some templates you can download from here. Note that the SNMP data query xml file contents all references to the data available in the OW-Server. However I had no time yet to create templates for all supported devices. At this time, only data/graph templates for DS18B20 and DS18S20 (temperature sensors) are implemented.
