But the plugin is still broken.....
I don't use the panel for X10.
More important than x10 is a few miscellaneous "thingies" such as Flags reside in the Units created by/dependent on the X10 polling of the plugin
Units 1-192 = X10
Units 193-200 = Relays
201-255 = Flags
I use flags to maintain an overall state of windows and cycle HVAC Off if windows are open and on when closed.
