A switch to ground can already be monitored as a contact in the SkyView EMS function. If it's connected to ground it shows closed, if it's not it shows open. This could be a switch, or could be an actual wire that gets physically broken.
This works for a switch. This does not always work if what you are connected to is some complex load that can do weird things when disconnected.
We need more information about exactly what you are trying to monitor. Are you trying to indicate when a breaker that powers something pops, when a physical wire gets broken, or ???
