Question on selling a lifetime tivo roamio

I purchased one of the renewed tivo roamio basic w/lifetime that they have on sale right now

I decided I really did not need it and listed it on ebay and it sold..... Is there anything I need to do for the new owner? Also would there be any way that I can have it removed from my "Tivo account" that shows my Roamio Plus, Mini and the Roamio basic I just sold.

Thanks
