Can't remove node Ecolink Motion Sensor Z-Wave

I’ve successfully paired 6 Ecolink motion sensors, however on the 7th one, I had problems pairing. It shows up on the Zwave manager but it doesn’t work. I tried every method to get it unpaired. The unpairing process for the Ecolink sensors is fairly easy. Take the battery out for 5 minutes and put it back in. I’ve successfully unpair multiple times, but I’m having trouble with this one.

Steps I’ve taken

1 remove node using Z-Wave Network Management.
2 “remove failed node” and “replace failed node” (Status is showing as Sleeping and not Dead)
3 Removed the Aeotec Z-Stick put it on exclusion mode and tried unpairing
4. Removed battery from Sensor and restarted HA in hopes of getting the Dead status

Nothing I’ve done worked, can anyone help me get back on track? Thanks in advance…

I have a Smartthing lying around so I tried to find the Ecolink sensor, sure enough I was able to find the sensor and pair it to Smartthings So the problem is that HA thinks that the sensor is still paired, can’t find any options to remove it from HA. Any help?

Here’s the log for the problematic sensor Node 13

Solved

Under Z-Wave Network Management exclude the problematic node, restart and wait 20 minutes. It becomes unknown, then remove failed node.
