MIMOlite Device Handler for Latching Relay

Has anyone written a Device Handler for use with the MIMOlite when used in Latching Relay Mode? I would like to monitor a 12vdc output that is constant, and report the status (active or off) to Smarthings so other devices can be triggered. Switching and alarms are not needed for my implementation. Thanks!

Did you ever find a solution? I am looking for something similar.
