Please be aware that coverage may change without notice due to factors outside Sentinel's control.

Boat Monitor consumes 1 Ah during a day of sailing and only 24 mAh while your boat is moored. The impact of Boat Monitor on your boat batteries should not be noticeable.

Yes, but very little. With a 100 Ah battery the Boat Monitor will work more than 6 months (this is without charging it).

You will receive a mobile push notification. You should be logged-in to the Sentinel app and have access to WiFi or 3G/4G.

GPS Tracking frequency is dynamic - it depends on whether the boat is turning, going straight or not moving at all. The resulting tracks are very detailed as can be seen in this image:

‍

For performance reasons the points may be slightly sparser when displaying the routes on your computer, phone or tablet. You can download the full track using the "Download GPX" button on any route in the web app.

When a guests scans the QR code and creates an account, you will be sent a guest request, which will allow the guest to see the routes and other information about the boat. You may confirm or reject the guest request by clicking on "Accept" or "Reject" buttons in the Guests section of the web application or within the application on your mobile device.

On your phone or tablet, install the application "Sentinel - your boat, online" which you may download from the App or Play Store (for Android or iOS respectively). Use the app to create an account. Scan the QR code on the front side of the device or provided by the "owner" of the boat.

Upon completion, the wizard will send a "guest request" to the boat owner for confirmation. After the request is accepted you will be able to start using the application.

‍

You may have activated the "anchor alarm" functionality, and the Sentinel service is warning you that your boat has moved from its initial position.

The CZone addon allows you to remotely switch selected CZone circuits and receive alerts from the CZone system. Two flavours of the addon are available: Unlimited and Lite

‍

The CZone Unlimited addon allows you to:

• Receive all alerts generated by the CZone system.
• Select and switch an unlimited number of CZone circuits. These are excluded from the subscription plan size limit.

‍

The CZone Lite addon allows you to:

• Receive all alerts generated by the CZone system. Some restrictions apply, see below *.
• Select and switch** a limited number of CZone circuits. Each selected switch takes one slot in your subscription plan size limit.

‍

* The behaviour of CZone alerts is different between Lite and Unlimited addons. With Unlimited, alerts that are cleared in the CZone system but triggered again will fire a push notification to the Sentinel app automatically. With Lite, alerts need to be cleared manually in the Sentinel app in order to receive new alerts from the CZone system (from same source).

‍

** When using CZone Lite, toggling a circuit in the CZone system will sync to the Sentinel app no later than every 20 minutes. Toggling a switch in the Sentinel app is reflected immediately in the CZone system. With Unlimited, the sync is always immediate.

‍

The CZone addon is not needed if you are only interested in monitoring CZone circuits (without switching and CZone alerts).
