NUT currently supports two fairly generic standards, SNMP and USB HID/PDC (in addition to a wide variety of proprietary protocols). The DS80C411 seems to support Ethernet, so SNMP might be an option. (Don't be fooled by how complex the host-side SNMP code is - SNMP is meant to be easy to implement on the embedded-device side, if you are serving up a static dataset.) You also mentioned USB above. If you go the USB route, and design a HID PDC (power device class) interface, it should be fairly simple to add support to the usbhid-ups module in NUT. It might also even work in other OSes. > The "PowerWhatch" module picks only the Voltage and Amperes and > Temperature from each of the 11 modules... and maybe it will store them > for a while in a 8-16 kByte NV-RAM or something like this... One thing that we currently don't do much with in NUT is deal with historical data - mostly because there are very few UPSes out there that return anything other than current status. You can, of course, log things external to NUT by querying it through the TCP client interface, and many people have stored the data in systems such as rrdtool or MRTG. -- - Charles Lepple _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
