The Bromic Smart-Heat App assigns Users to sites and there are 2 types of User roles. Admin Users have complete access and control of the site setup. User roles are restricted to operational control of the appliances.
Both types of users are added to a site by invitation unless it is a new installation, the user that creates the site is automatically assigned as an Admin user. Admin users having complete control of the site setup are responsible for inviting other users. Go to Manage Users under the settings menu to invite new members by entering their name and email address. All members need to download the app, register, and confirm their invitation by email.
