Remove the device from Inbox

Recently entered a headache problem, remove the Inbox after the device and did not really delete! When I add the device again, it re-displays the device that has been deleted, but these devices do not work properly, either do not recognize the device or the device that has left the current Zwave network. Is there any good way to solve this problem?
Thank you very much!

You need to go into HABmin and remove the bad nodes from the controller. As long as the controller still has a device mapped to that node it will keep showing up in your inbox.

But the question is coming!
Why I will power all the equipment, habmin will show the device online. I would like to know how this is the state of the device? Is it a regular refresh? How long is the delay?
