Why Is Your Eufy S330 Offline? (100% Working Solutions!)

If you’re constantly having your eufy S330 offline, this can represent quite a significant threat to the premises’ security, which is unacceptable.

At ZontSound, we expect 24/7 availability from a security camera, and if yours keeps going offline constantly, you’ll be missing important events.

The common causes for this issue often include an unstable Wi-Fi connection, an outdated version of the OS, and lasting power supply disruptions.

So, proceed further into the guide to discover all effective solutions!

How to Fix the eufy S330 Offline Problem? (8 Quick Steps)

Note: Have you checked if there is a red light indication on your eufy S330 camera?

1. Refresh the eufy Camera Wi-Fi Status

When the status of the eufy S330 switches to “Offline” within the app, it does not always mean that the camera has lost connection.

Hence, eufy has designed a status “Refresh” function that updates the connection indicator of your camera. 

All you have to do is tap the Refresh Icon visible in the application’s interface and wait for a few seconds until the camera details update.

If the eufy camera’s Wi-Fi details are not outdated, the status should switch back to “Online” in a brief moment after pressing the refresh button icon.

Important: If this resolves your problem, we strongly recommend continuing troubleshooting, as it’s unclear when the camera would go “Offline” again.

2. Update the HomeBase Wi-Fi Details

The eufy S330 camera does not connect to the internet directly, but uses the existing connection of the eufy HomeBase.

So, in case the HomeBase has lost connection to the internet, so will the eufy S330, and the only resolution is to update the HomeBase Wi-Fi.

Here’s how to update the eufy HomeBase Wi-Fi details:

1. Launch the eufySecurity app and head to the Devices tab.
2. Select your HomeBase, then navigate to the General page.
3. Access the Connection, and then the Wi-Fi Setup section.
4. Choose your 2.4GHz Wi-Fi network from the list in the app.
5. Enter the password for the 2.4GHz network and tap Next.
6. After that, wait until the HomeBase reconnects to the Wi-Fi.

Tip: Follow the instructions from solution #1 to refresh the Wi-Fi status of the camera and determine if the issue is still there. 

3. Power Reset the Router, HomeBase & Camera

Since it is still unclear whether the HomeBase, network router, or your eufy S330 camera is at fault, we recommend conducting a power reset.

We mean your entire equipment, one by one!

3.1 How to Power Reset the Router:

1. Unplug the router power cord from the A/C outlet.
2. Wait 30 seconds to allow a full system discharge.
3. Reconnect the router and wait for a reboot.

3.2 How to Power Reset the HomeBase:

1. Disconnect the HomeBase power adapter.
2. Wait 30 seconds until the device discharges.
3. Reconnect the power cable and test the unit.

3.3 How to Power Reset the eufy S330 Camera:

1. First, find the Sync button on the eufy S330 camera.
2. Press the button 5 times quickly to turn off the unit.
3. Wait for ~10 seconds, then reboot the eufy camera.

After discharging each of the devices in your system, check the eufy Security app to confirm the S330 status has changed to “Online”.

Keep in mind that you might have to reconnect the eufy HomeBase to Wi-Fi after completing the power reset. 

4. Charge the eufy S330 to Maximum Battery

The reason for the Eufy S330 camera’s offline status might be power-related, specifically with the charging of the device.

Fully recharging the camera to maximum capacity ensures the S330 functions properly, without powering off due to power insufficiency. 

Wait for at least 10–15 minutes after fully recharging the camera and check if the Wi-Fi status changes from “Online” to “Offline”.

This way, you can identify the exact moment at which your camera loses connection and determine if the charging is involved in any way. 

5. Shorten the Camera-HomeBase Distance

The eufy S330 camera might keep losing connection if it is too far away from the HomeBase or there is a large amount of obstructions in-between.

A wall or two is often not a problem for the 2.4 GHz, but positioning the camera beyond 100 feet from the HomeBase could be a problem. 

So, place the eufy S330 within two feet of the HomeBase 3, follow the instructions in solution #2 to update the HomeBase Wi-Fi details, then slowly move the camera away.

Keep checking and refreshing the eufy S330 camera Wi-Fi status within the eufy Security app during that time.

6. Re-add the eufy S330 Device Profile

Well, a synchronization problem with the HomeBase could disrupt the Wi-Fi connection of the camera, leading to persistent losses of the reception.

Removing and re-adding the camera in the eufy Security application can address everything at once.

Step #1 Remove the eufy S330 from the App:

1. Enter the eufy app and select your S330 device.
2. Head to the Device Settings pane in the section.
3. Press “Remove Device” to delete the S330 profile.

Step #2 Re-add the eufy S330 to the App:

1. Launch your eufy app and press the “+” icon.
2. Choose Add Device from the drop-down menu.
3. Now, select eufyCam 3/eufyCam 3C in the tab.
4. Pick HomeBase 3 as the base station in settings.
5. Press the SYNC button on the S330 until it beeps.
6. Tap Next and wait for the HomeBase 3 to connect.

All camera settings in the app will be erased after removal.

Don’t forget to keep the camera within 10 feet of the HomeBase during resynchronization and wait for the status to display “Online” within the mobile application.

Tip: If you fail to connect your eufy S330 camera to the app, find more info at the eufy official!

7. Troubleshoot Issues with the Network

If your eufy S330 camera is still unable to establish a secure connection, the issue could be with the Wi-Fi network.

So, ZontSound recommends several different methods to address potentially underlying issues with the network equipment.

7.1: Reduce Network Usage:

Start by disconnecting unnecessary devices from your Wi-Fi to reduce the bandwidth usage, ensuring the 2.4 GHz band has enough capacity for your eufy S330. 

This helps prevent connection disruptions that might cause the camera to go offline consistently. 

7.2: Reset the Wi-Fi Router:

Locate the Reset button of your router, press it for 10 seconds to perform a factory reset, then reconfigure the 2.4 GHz Wi-Fi network.

We only recommend this step when you are confident that you can rebuild the network configuration of your router.

If not, get in touch with your ISP.

Warning: Resetting the router will erase all network configurations and settings, so you’ll need to set up your router from scratch.

7.3: Test on a Mobile Hotspot:

If troubleshooting the network does not resolve the problem, try updating the HomeBase details to your smartphone hotspot instead.

Simply activate the personal hotspot function of the phone, then follow the instructions in solution #2 to pair the HomeBase with your smartphone and test.

8. Factory reset the eufy S330 Camera

If the Eufy S330 is offline regardless of the solutions you have attempted so far, a factory reset is your resort.

Unfortunately, all of the camera Wi-Fi details and settings will be erased by the factory reset, hopefully along with the underlying Wi-FI errors.

Here’s how to reset the eufy S330 camera to factory settings in easy steps:

• First, find the SYNC button on the eufy S330 camera rear panel.
• Press and hold for around ~15–20 seconds to begin the reset.
• Release the button once the camera has shut down completely.
• Re-synchronize the camera with the app once the reset is done.

Note: If your camera remains “Offline” after everything you’ve tried, perhaps your product has a defect, and the best course of action would be to contact eufy Customer Service.
