I am using your excellent plugin(s) to control a couple of pio receivers.
It is working well (although I suffer the pesky Amazon Echo connection issue).

Anyway, my main interface to my system is iRule and I need a way of pushing any status change to iRule so it can update buttons/labels etc...

I use drule's ip/serial plugin for this. It works well.

Here's where I'm stuck. I need to somehow trigger a script every time a value changes in an UltraPioneer AVR device. I would need to access the device, and the new value. I could set up 500 events with triggers but that seems totally crackers. Any ideas how I could pull this off more simply? Would be awesome if I could set a global setting in UltrPioneer and give it a scriptname and then the plugin calls that script with DevRef and Value as Params.
