I have attached a screen shot of this Node after removing and reinstalling a Go Control garage door opener. I have had a lot of issues with the opener recently ...not reporting the true state and not working at all. I replaced the battery and that didn't help .
For a battery powered device that is still in the system you may have luck if you take out the batteries when you try the "Remove" button in the zwave list. If the device replies back the remove will fail and taking out the batteries prevent that.
It looks like it is an unsuccessful pairing of your Garage Door. If you power down the Garage Door and then hit Refresh a few times it should come up with a Remove option. After removing you could then repower your Garage Door and you should be good.
I have trouble with mine as well for a device up high the radio in it sucks. It needs to be s2 and recommend u put an extender or switch in the garage and one on wall on other side of garage towards hub.
@user1628 - in case you run into future issues like this - a ghost can result from a failed/incomplete pairing of a Z-Wave device. The ghost is usually closely followed by the actual device that caused it in the Z-Wave Details page. E.g., in your case, you try to pair the garage door opener and the pairing doesn't complete properly and the ghost device (035) is created. You try to pair it again, and the pairing is successful and the normal device (041) is created. Note the "SPECIFIC_TYPE_SECURE_BARRIER_ADDON" description in the middle column that is a clue to help you figure out what device caused it.
Ok, removed power to the opener and went to the details page and clicked remove under the ghost node. Did not remove after the 1st try and did it 10 plus times…still there
Shut down the hub and removed power and repeated the process ..
the ghost node is still showing up.
Any further help would be appreciated.
