       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.

       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.
