OK, in plugin.py I know I can access device plugin properties with dev.pluginProps and I can access states with dev.states (where dev is the device reference), but how do I access the UI values I entered into a device settings form (Devices.xml)?
I know some methods in plugin.py expose valuesDict or validateDict, but this is not exposed in the deviceStartComm method in plugin.py that I need this from so that I can set the address property to one of these values on the devices UI form.
I've trawled the Indigo documentation and Google for about 3 hours and can't work it out
