Provided that you have the Owner role in a home, you can at any time edit the details of other users (including other owners).

To do so:

  1. In the WiZ app, open the Settings tab
  2. Under "Current home", tap on the Members tile
  3. Tap on the home member you want to edit
  4. Edit the various parameters, which include
    1. member's name
    2. role in this home
    3. if the role is user or guest, access duration

If you wish to delete the home member instead, locate the trashcan icon in the top right corner of the member details page, and tap on it.
