How do I register this device for admin if it was used by someone else?
Did the person from whom you purchased the hub perform a full reset first? That wipes the hub and de-registers that person's Hubitat account from being associated with the hub.
The previous owner would have to provide you the admin login/password, or initiate the transfer for you.
From the FAQ:
Log into my.hubitat.com with your current admin account and select Registered Hub then select Hub Details . On the Hub Details you will see a place where you can Replace existing Admin with a different Hubitat user. Be sure to create a Hubitat Account for your new email by visiting the following page: My Hubitat
I bought it on ebay. I don't know who the previous owner.
Presumably the eBay seller can provide that information to you?
Can you email him to remove the hubitat from his account at my.hubiat.com ?
This is a completely unacceptable answer. As long as there is some sort of verification of new ownership, hubitat should be able to de-register it for use by a new person. I bought mine from Amazon (not a private seller) and it already is registered to another admin account. There doesn't seem to be any support options for this scenario.
Amazon is not supposed to send out returned units, but they have been. So it is likely Support can/will help you reset the unit.
Your situation is very different than someone purchasing a “used” hub from eBay, which is of indeterminate provenance. It is not uncommon for stolen merchandise to be sold on eBay.
Sorry for the confusion. If you could please open a return case using the "Hub is not new" option, we would be glad to take care of the replacement. Unfortunately, Amazon has been known to put a returned unit back in stock from time to time.
I have this same issue. Is there a reset for this or do I have to return to Amazon?
@bobbyD see above. Do I have to return this or can you reset it remotely?
Yes, please send me a private message along with your Hubitat account and hub ID (or MAC address).
