custom pollers

Good Day
I have a client of our orion that requested some custom mibs polled. It has to do with remote buildings and things like door alarms, power failures, generator status etc.
The orion custom poller works fine but the results are numeric, for example a value of 3 for a closed door and 4 for an opened door. What my client would like to see is a green dot for a closed door and a red dot for an opened door. Has anyone played with this already and willing to share your ideas??
