I been hours to figure out this, I installed Zensys tools and I found many discrepancies between what is in the USB stick and what I see in the HE hub. I know I complained of this before, I believe in upgrade 1.1.2.112 the z wave table was modified, now we can't see failed devices and or remove them when the red button appeared, I remember to use the feature, sometimes it had the initialize button.
I can see that my stick has multiples nodes that I removed, that includes the HEM, an Iris repeater, multiple GE dimmers, I can't modify anything but I can test switching all on and off and they work, everything turns on quickly at the same time.
Per the tools, those "removed" nodes are active, unfortunately the node 2, which I removed from HE, was the first device I installed, the nearest to the hub and it was z wave non plus GE dimmer, I can see the topology map and it confirms that my mesh is trying to go through a non existing node. This plus about 6 more probably is causing the problem of the slowing mesh.
I need @bravenel and @bobbyD look in to this.
My z wave mesh is frozen, everything in zigbee works fine.
