I had someone walk away with 4 of my HS103's. They are still on my Kasa Account, I haven't removed them from the app, hoping they will show backup. Since all devices have a unique MAC Address, and they are still registered devices on my Kasa Account, will I be notified if someone tries to register them on their account, will they be notified it can't be used since it is associated with another account?

I have an idea of who has them, just want to make sure it's like most of the other devices that have a MAC Address, it can be associated with 1 account.
