If you would like your friend, for example, to also use your iKettle 3rd generation, what you can do is invite them to your network. No need to re-blink up!
All your friend needs to do is download the Smarter app and create an account.
You will then go into your network and select add user, a pop-up will appear asking you to enter their account email, the app will generate a share link then give you the option to email them the link.
Once they have received the email all the need to do is open the link in their mobile and they are now able to use your iKettle 3rd generation.
