Let's consider the following case:
  • I create a home on one phone and sign in, for example with Facebook
  • I create a different home on another phone, and then attempt to sign with the same Facebook account.
What happens then?

WiZ will automatically merge the two accounts. You will be signed in with Facebook on both devices, and see both homes on both devices.

The only cases when account merging will not work are:
  • If you use different accounts (e.g. two different Facebook accounts, or one Facebook account and one Google account...)
  • If you use several providers, and some accounts aren't the same. For example, you signed in on one device with a certain Google account, on another device with another Google account, and you are now trying to link the same Facebook account to both devices.
