Supported hardware

The Richcomm dry-contact to USB solution is a generic interface that is used to upgrade an existing (RS-232) contact closure UPS interface to USB. As such, all the limitations of the underlying contact closure interface apply. This means that you will only get the essentials in ups.status: OL, OB, and LB. See also genericups(8).

Bugs

Most contact-closure UPSes will not power down the load if the line power is present. This can create a race when using secondary upsmon(8) systems. See the upsmon(8) man page for more information.

The solution to both of these problems is to upgrade to a smart protocol UPS of some kind that allows detection and proper load cycling on command.
