This article explains where to find the Serial Number (SN) and Product Number (PN) on eufy devices.

Knowing your product’s SN and PN helps us provide accurate customer support, warranty service, and repair options.

You can find this information on the device itself or, for supported models, in the eufy app.

Where to Find the Serial Number (SN)

For eufy RoboVac devices：

1. On the device

Most Devices

Location: on the bottom of the robot, or on the back of the base station

S1 Pro (PN: T2080)

Location: The SN is located under the dustbin.

• Open the magnetic top cover, remove the dustbin, and you will see the SN inside (below the QR code).

2. In the App (Wi-Fi–Enabled Models Only)

If your device supports Wi-Fi and can connect to the app, you can view the SN directly in the app.

• App → Settings → Device Information (Device ID)

Note

• Only Wi-Fi–enabled models display a Device ID in the app.

• Older models (such as RoboVac 11S) do not support app connections and do not have a Device ID.

Important:

• Only Wi-Fi–enabled models display a Device ID in the app.

• Some older or non–Wi-Fi models (such as RoboVac 11S) do not support app connection, so it is normal that no Device ID is available.

For eufy security devices：

1. On the device

The serial number (SN) can be found printed on the back of the camera.

2. In the App 

You can find the SN in the app by navigating to:

Device Settings > General > About Device> Serial Number

Tip：The PN is often located near the SN label or on the device’s rating label.
