If you leave your boat to go ashore and take your iPhone with you, your phone will lose its Wi-Fi connection to the DataHub once you move out of range. The Anchor Alert App does not send a notification to tell you that the Wi-Fi connection to the DataHub has been lost.

However, if your iPhone has a cellular internet connection, you can still receive Anchor Alert notifications for any alerts you have enabled, such as drag, swing, scope, wind speed, wind gust, wind direction, depth, or AIS alerts. Notifications are delivered to your iPhone via cellular data in the same way you would receive other app notifications, such as a WhatsApp message.

How can I check the connection to my DataHub?

When you reopen the Anchor Alert App, it will detect that your phone is no longer connected directly to the DataHub. The Wi-Fi radio waves in the top-left corner will display in red to indicate that the connection has been lost.

To check the latest information from your boat:

Check the large green REFRESH button. This updates automatically approximately every minute, but you can tap REFRESH and wait around five seconds to retrieve the latest information from the server.

Return to the Anchor Map screen to see your boat at its latest reported position.

1. Go to Dashboard &gt; N2K Data.
2. Check the large green REFRESH button. This updates automatically approximately every minute, but you can tap REFRESH and wait around five seconds to retrieve the latest information from the server.
3. Return to the Anchor Map screen to see your boat at its latest reported position.

Keep your DataHub connected to the internet

Before leaving the boat, make sure your DataHub has a reliable internet connection that will remain powered on while you are away. You can connect your DataHub to the internet using:

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.
