@csteele thanks for your info, I got the ghost nodes removed and immediately I saw a change in my Z-Wave network speed, even deleting other nodes were faster after I deleted the node 2 of my mesh.
@bravenel Definitive the hub has something weird with ghost nodes, I'm not sure if this was corrected already but I deleted 4 GE dimmers after latest update 1.1.3.116 and they were there in the stick as ghost nodes, after I removed node 2, it took about 5 minutes, then everything else was faster.
Using Zensys I tested with my cloned stick first, I found ghost nodes 2,8,9,33,59 and 63. I removed them, everything was fine so I proceed to do the same on the HE stick, I noticed that node 8 was removed already by HE, I removed 2,9,33,59 and 63.
Right now everything looks stable, I will keep posting if I see something else.
Thanks
