Nucleus offers two types of connections between devices: Home and Remote. All devices in the Home group can see and call each other. Even devices at different locations can be added as Home connections. After your first Nucleus is set up, you will receive a Home code in your email. Using this code will make it easy to set up additional Nucleus devices in your Home group. Mobile devices are added as Home connections as well.
If you wish to connect with someone outside of your family, you can choose to share your Nucleus device by going to Settings > Add or Manage Devices > Share this Device. The person you share with will receive a Remote code via email that they can input into any of their Nucleus devices. Once you approve the connection, their device will show up in your Remote tab. Remote connections are one to one–the person you invite to connect can only call the Nucleus you invited them from.
Please note: mobile devices cannot be added as Remote connections, and a Nucleus needs to be set up as part of an existing family or with a new account before it can be added as a Remote connection.
