@GeordieDave is it possible to register pre-owned (registered to another account) deco to another account by factory reset?  i will buy used Deco devices and i want to make sure i can use them after factory reset.

@whiteface  pre owned is no problem as it's the user who is registered rather than the unit.  Set yourself up and then simply add the new (second hand - reset) decos to your system. It's no different to resetting your own decos. Have fun.
