Is there an api for status?

If you subscribe to ISY events, you will see event type _21 (<control> tag) with one of the following status values (<action> tag):

2.1 - Not in discovery mode                                           
2.2 - Include a Z-Wave device                                         
2.3 - Exclude a Z-Wave device                                         
2.4 - As Primary, Replicate to controller and make it the new Primary 
2.5 - Learn mode                                                      
2.6 - Replace Failed Node (similar to Include)                        
2.7 - Verifying the node is a failed node                             

e.g. Currently including a Z-Wave device
<Event seqnum="25" SID="uuid:27">
    <control>_21</control>
    <action>2.2</action>
    <node/>
    <eventInfo/>
</Event>

I withdraw my objection .  I was able to add the new devices from their final locations tonight, and I think the problem was that my mesh was insufficient before.  I noticed that the first one I added showed a bunch of retries as it the ISY added it, and successive devices were much smoother.  Now that I've added 4 more devices I hope the mesh is a lot stronger.
