Don’t believe so. The factory reset, which de-registers the hub, wipes it for security reasons. I know this to be the case because a week or two ago, I de-registered my spare C-7 and sent it to a community member who was having Z-Wave difficulties.
What I have done is to register the hub and all integrations, etc., to the house, which has its own email address just for home automation things. I’ve also got a folder with all settings, IP addresses, passwords for each automation (of course, different passwords for each) printed out.
That way, when/if we sell the house or when I die, the next owner gets that folder and can change passwords as they wish, with no access to my or my wife’s personal emails. My wife insists that she is leaving the house when I die because she won’t be able to maintain the smart home stuff.
And welcome to the community.
