Any new users who wish to be added to the system, must go through the same association process as the first user, using their own email address / account.

The first person to create an account (primary user) and connect to the Hub is able to manage the accounts of the subsequent users (secondary users).


iOS / Android Web app



Primary user

The primary user can manage the secondary user accounts, and can decide whether they can:

  • Manage heating
  • Users who can edit schedules are able to create, edit and delete heating schedules. They are also able to add and remove devices to the Cosy system (such as using the Welcome home feature).
  • Manage accounts 
  • Users who can manage accounts have the same account management controls as primary users (they can manage other accounts and delete other accounts). 
  • Delete users
  • Primary users are able to delete other primary and secondary users.
