Surface Requirements

The hub should be placed on a flat, stable, and level surface. Avoid placing the hub on uneven or unstable surfaces where it could fall. Do not place the hub on or near heat sources, in direct sunlight, or in environments where it may be exposed to moisture.

Setup

Step 1: Connect Power

1. Insert the small end of the included USB cable into the power port on the back of the hub.
2. Insert the other end of the cable into the included power adapter.
3. Plug the adapter into a standard wall outlet.
4. Confirm that the cord is routed away from any crib or other sleep surface and remains at least 3 feet (0.9 m) from any place a child sleeps or plays.

The hub will power on automatically. The status indicator LED will illuminate.

Step 2: Download the Dozzi App

The Dozzi app is required to operate the hub.

• iOS: Search for "Dozzi" in the App Store, or scan the QR code on the Quick-Start Insert.
• Android: Search for "Dozzi" in Google Play, or scan the QR code on the Quick-Start Insert.

Step 3: Create or Sign In to Your Dozzi Account

Open the Dozzi app and follow the on-screen instructions to create a new account or sign in to an existing account. A valid email address is required.

Step 4: Pair the Hub

1. In the Dozzi app, tap Add Device.
2. Follow the in-app instructions to enable Bluetooth on your phone.
3. The app will detect the hub and guide you through Bluetooth Low Energy (BLE) pairing.
4. When prompted, enter your home Wi-Fi network name and password. The hub connects to 2.4 GHz Wi-Fi networks.
5. Wait for the hub to complete its initial connection. The status LED will indicate when pairing is complete.

Operation

Status Indicators

The status LED on the hub indicates current state:

• Solid green: Connected to Wi-Fi and operating normally
• Slow blinking: Pairing mode (waiting for app connection)
• Fast blinking: Cry detected
  

Receiving Alerts

The hub continuously monitors for infant sounds and routes alerts to paired devices. When an alert is triggered, you will receive a notification via the Dozzi app on your phone and your paired Apple Watch or Wear OS device.

Adjusting Sensitivity

In the Dozzi app, you can adjust alert sensitivity to match your environment and preferences. Higher sensitivity detects quieter sounds; lower sensitivity ignores ambient noise. Find the setting that works best in your home.

Co-Caregiver Setup

Invite a partner or other authorized caregiver to share alerts. Dozzi allows for users to decide which method determines which caregivers receives an alert. There are four modes to choose from: Smart, Alternate, Schedule, or Broadcast.

Smart: the caregiver in the lighter sleep state receives the alert.

Alternate: the alerts switch between caregivers.

Schedule: one caregiver receives all the alerts during one shift and the other receives all the alerts in the second shift.

Broadcast: all alerts go to all monitoring caregivers.

Apple Watch and Wear OS Integration

The Dozzi app supports paired smartwatches for delivering alerts to your wrist. Configure smartwatch pairing in the Dozzi app settings. Critical Alerts (iOS) are supported for high-priority notifications.

Turning Off the Hub

To turn off the hub, unplug the power adapter from the wall outlet. The hub does not have a power button.

Care and Maintenance

Cleaning

Clean the hub exterior with a dry or slightly damp soft cloth. Do not use liquids, sprays, abrasive cleaners, or solvents. Do not allow moisture to enter the hub through any opening.

The cord and adapter may be wiped with a slightly damp soft cloth. Do not submerge in water. Disconnect from power before cleaning.

Cord Inspection

Inspect the cord regularly for signs of damage:

• Cuts, fraying, or exposed wires
• Cracking or splitting of the jacket
• Loose or damaged connectors
• Discoloration or burning around connection points

If any damage is found, stop using the product immediately and contact Dozzi Sleep Systems LLC for a replacement cord. Do not attempt to repair a damaged cord.

Storage

If the hub will not be used for an extended period, unplug it from the wall outlet and store it in a clean, dry location away from direct sunlight and extreme temperatures.
