@rwidman, nothing special. After permanent installation of the outlet device, I just fired up the ST app and used the Connect Now feature for generic device addition. While ST is searching, press the button on the outlet faceplate slowly (approx. 1-2 second interval) a few times and it eventually sees it.
Now, the removal process wasn’t quite so reliable for me. Most of my outlets were migrated from a Honeywell Tuxedo Touch panel. I had to run through the remove device process probably a dozen times for each one before it actually worked. I think the issue there is that to remove it, you have to put the Z-Wave controller into removal mode and then press the faceplate button twice… but nowhere does it say how fast to press the button twice. I had the most luck with timing just slightly slower than a standard “double-click” of a mouse button.
