It's wild ... I picked a wired KPL and did a restore device and watched the Event Viewer log run through the restoration ... and then when it was done, cleared the viewer and when pushing any of the buttons on the KPL, there is no activity ...
Here is a shot showing the full PLM Links Table, a compare of that KPL ... and then the event viewer ... it was showing activity when I ran the "start" for each of the links table and the compare ... and then I cleared it and pushed the buttons on the KPL ... on, off, fast on, fast off, etc. That KPL is linked to three other hardwired devices and a no-load switch (for virtual 3-way) ... but there is not events showing for any of them ... hmm.....
