UnDP Custom Gauges

Good afternoon

I have three UPS to monitor, I set up UnDP's to monitor the Input Line Voltage, now I want to display the results on a web page. I am using the triple custom poller to display the three phases for each UPS. However each of the three custom poller gauges only diisplays data from one of the UPS  so I have 9 gauges showing the lime voltage for the pahes of one UPS. How can I point the custom poller at a specific UPS?
