OpenUPSmart

Go NUT(s)!

12-12-2008

All units supported by OpenUPSmart should now be supported by the Network UPS Tools. If you are having issues with any of the UPS units previously supported by OpenUPSmart they will be happy to help.

OpenUPSmart should be considered retired; NUT is your best choice for robust UPS support.

About

OpenUPSmart is a UNIX based daemon mainly for the no name UPS available from Dick Smith Electronics in Australia. It is listed on the website simply as “UPS Power Supply UPS0400 400VA”, but otherwise has no unique identifying features. If you know anything more about this little UPS, please contact us!

Update: Thanks to the Google cache, this appears to be called the “Micro Master” UPS, originally made by a company called Centralion.

The Protocol

At first OpenUPSmart used data gleened from sniffing the serial line with the Windows software. On later investigation the protocol appears to be based on the Megatec protocol, available here. (thanks to Chris Barnesfor relating this to the sniffed commands). Although the particular UPS pictured and originally targetted does not appear to be able to handle all of the commands.

The Software

The software is aimed as a daemon based replacement for the Commander Pro software available from www.ups-software-download.com It appears to be authored by a company called Waytech.

If your UPS uses software from this site, you should be able to replace it with OpenUPSmart. Please report any success.

The Linux software available from that site in RPM format is called UPSmart (hence OpenUPSmart).

The goal of OpenUPSmart is to communicate with the UPS, poll it periodically for status updates and run commands on event changes (power failure, power restore, etc).

The software is targetted at building and running on Linux and NetBSD but should be portable to any UNIX style operating system.

The SourceForge project page is available here.

Sample Output

MRTG Output

OpenUPSmart can optionally create a thread that listens on a specified port and reports status information. This can be easily plugged into MRTG.

Here is an example of how it works

gnuplot output

Here is a little of the logging information OpenUPSmart can show via gnuplot.

Console output

You can also assign various levels of console based output which is often useful for debugging your setup.
