Power cycle your router first, then verify that your Eufy doorbell is connected to a 2.4GHz Wi-Fi network (the wired doorbell requires this; the S4 also supports 5GHz). This resolves most offline doorbells, missing video, and failed connections. If a wired doorbell still acts up, the next suspect is weak power from the transformer, the small box that steps your home’s electricity down to doorbell voltage. When the doorbell connects but remains quiet, the issue typically lies in a notification or chime setting.
The list below starts with the most common problems and ends with the rarest ones. Every entry indicates which models it covers: the wired doorbell, battery models, the Video Doorbell Dual, the eufy Video Doorbell E340, and the Video Doorbell S4 (T8215), which is compatible with a HomeBase (the small hub that plugs into your router). Menus vary slightly by model, so if an app screen looks different, find the closest match in your doorbell’s settings. The app is now named Anker eufy. Previous versions were called eufy Security.
1. Eufy Doorbell Offline
A doorbell that is offline has lost its internet connection. The cause is typically the router, the HomeBase, the Wi-Fi band, a weak signal or, on wired models, weak power.
- While connected to your home Wi-Fi, pull up a web page on your phone. Should the page fail to load, your internet is at fault rather than the doorbell. Power down the router, reconnect it, and allow several minutes. Your cameras and everything else on that router will lose connection for a short time.
- If your doorbell has a HomeBase (the S4 can), check the HomeBase light. A blue light means the connection is normal. A red light indicates the HomeBase is offline, so address the internet connection first by restarting the router and inspecting the cable linking the HomeBase to the router.
- In your router’s app or admin page, review the Wi-Fi settings. Eufy wired doorbells work solely on a 2.4GHz network rather than 5GHz. Your Wi-Fi network name (SSID) needs to be visible, and you need to set the security type to WPA or WPA2.
- Bring the doorbell nearer to your router or HomeBase, or shift the router or HomeBase closer to your door. Eufy lists this as an S4 solution for losing connection. A metal wall or similar metal barrier located between the doorbell and the router reduces signal strength.
- For wired models or the S4, verify that your doorbell is receiving 16-24V AC power. Entry 6 shows how.
- If it is still offline, delete the doorbell from your app, then add it back. Entry 8 contains the instructions plus a warning regarding the lack of service.
A Eufy community moderator proposes that battery doorbell owners temporarily relocate the HomeBase nearer to the doorbell for several days to check whether the dropouts cease. This is advice from the community, not an official fix from Eufy.
The issue is resolved once the doorbell appears online in the app and live view launches. When Eufy cameras using that HomeBase lose connection too, the Eufy camera problems guide addresses the camera side.
2. Eufy P2P Connection Failure
P2P (peer-to-peer) opens a direct line from your phone to the doorbell for live video. If that connection drops, the app displays a connection error and no video. The issue typically stems from your phone’s network, the router, or the Wi-Fi band.
- Fully exit the app, then relaunch it.
- Switch your phone from Wi-Fi to cellular data and attempt it once more. When the connection succeeds, the issue lies with your home network rather than your doorbell.
- Follow the instructions in entry 1 to restart the router.
- Make sure your wired doorbell is on a 2.4GHz network, with a visible name and WPA or WPA2 security (entry 1, step 3).
- Temporarily halt video streaming or big downloads on other devices for a few minutes. Live connections can fail when a network is busy.
After the fix, the live video appears in a few seconds. If live view is the only issue you’re experiencing, proceed to entry 4.
3. Eufy Doorbell Not Sending Notifications
When the doorbell is online but your phone remains quiet, a notification switch is disabled in the app or on the phone. Eufy lists these checks for the Video Doorbell Dual, and the same switches exist on other models.
- In the app, open the doorbell and confirm “Motion Detection” is enabled.
- Open “Notification Settings” for the doorbell and ensure that both “Doorbell Ring” and “Motion Detect” are on.
- In the settings of your phone, turn on notifications for the Anker eufy app. Also confirm that Do Not Disturb, a Focus mode or battery saver isn’t blocking it.
- See if the missed ring or motion got recorded in the app. If the clip exists but the alert never arrived, the notification path is the problem. The doorbell was probably offline if there is no clip (entry 1).
- If the issue persists, delete and reinstall the app, then sign back in. First, make sure you have your account email and password ready.
Should alerts remain absent for you, jot down precisely when a clip occurred that produced none. Eufy support needs that specific time, along with the device logs, to investigate the issue.
Once a test press of the doorbell button triggers an alert on your phone, the issue is resolved.
4. Eufy Doorbell Live View Not Working
If live view stops working, first check if you can reach the doorbell at all. Eufy begins its troubleshooting for the Video Doorbell Dual with this check.
- Open “Main Page” › “Smart” › “Events” and play a recorded video. If recorded videos play, the doorbell is online and the issue is limited to the live stream. If they also do not play, treat it as an offline doorbell (entry 1).
- Try switching your phone to mobile data or another Wi-Fi network, then reopen the live view.
- Try live view on a second phone after signing in there. Should it work, the issue lies with the first phone or its app.
- Pause heavy activity on your home network for a few minutes. Heavy traffic on your network can cause live streams to fail.
- Power cycle the router (entry 1, step 1), then attempt it once more.
Live view should now come up and display the camera feed from your door. With different models, the “Smart” and “Events” labels might vary a bit, so check for the list of recorded clips.
5. Eufy Doorbell Chime Not Ringing
Your phone receives the ring, but the indoor chime remains silent. Usually the issue is an incorrect chime type, the app’s mechanical chime setting is disabled, or the transformer falls beyond the necessary 16-24V range. Eufy lists the specifics for the E340 in its E340 and indoor chime troubleshooting article (new tab). Consult your own model’s manual for other wired doorbells.
- Determine which type of chime is installed in your home. A mechanical chime relies on physical bells and hammers to produce a “ding-dong” sound. Electronic tones are played through a small speaker by a digital chime. Check the chime’s label or model name, or look in its manual. The E340 is compatible solely with mechanical chimes. Digital chimes are not compatible.
- In the app, open the doorbell’s settings and enable the mechanical chime option. It remains off until you turn it on. The precise name differs depending on the model and app version.
- Confirm the transformer’s output reads 16-24V (entry 6).
- Ensure the blue bypass wire is not connected to anything. Before examining any wiring, shut off the electricity at the circuit breaker.
- If your chime is digital, swap it out for a mechanical one.
If you’re installing the E340, skip the blue bypass wire. According to Eufy, the chime will not function if you use it. Shut off the circuit breaker prior to making contact with any wires.
If the chime still stays silent, reach out to Eufy support (see the last section) and give them the chime make and model.
The issue is resolved when pressing the button triggers the chime and your phone notifies you.
6. Eufy Wired Doorbell Not Getting Enough Power
A wired Eufy doorbell requires 16-24V AC power from the transformer. Under that range it may go offline, not complete setup or behave strangely. Your transformer also needs to have a rating of 30VA or higher, and an aging doorbell transformer designed for a basic buzzer might not be sufficient.
- Before you touch any wiring, switch off the doorbell circuit’s power at the circuit breaker.
- Check the transformer’s label. The output voltage is displayed. Seek 16-24V AC, rated at 30VA minimum. Eufy’s requirement is not met by a transformer outside that range. If you cannot read the label without opening an electrical panel, ask a licensed electrician to check it.
- When setting up, run the “Voltage Diagnosis” test. Eufy’s wired doorbell setup flow starts by connecting the doorbell to the transformer, then adding it through “Devices” › “Add Device” › “Wired Doorbell”, scanning the QR code, pressing the button until it dings, and running the test. The transformer’s power supply is verified by this test.
- Should the test fail, a licensed electrician should swap out the transformer for one rated for 16-24V AC.
- Once the power is back on, run the test again and make sure the doorbell stays online.
The doorbell is fixed once the test passes and the app keeps it online for a full day without dropping.
7. Eufy Doorbell Randomly Rings
Should your doorbell ring on its own, check the button and the firmware first (the doorbell’s internal software). Eufy lacks a confirmed public fix for this issue, so reach out to support should the following steps fail to help.
- Check the button. Dust, dirt, bugs or dampness can hold it down.
- Wipe the button area using a soft, dry or slightly moistened cloth. Avoid spraying liquid into the gaps, and do not open the doorbell.
- In the app, access your doorbell’s settings and check for a firmware or “About” option to find out whether an update is available. Depending on the model and app version, this label varies. Keep the doorbell powered and install any update until it finishes.
- Should the ringing persist, verify your Wi-Fi connection (entries 1 and 2), then reach out to Eufy support.
Fixed indicates the doorbell will not ring for an entire day if no one activates the button.
8. Eufy Doorbell Change Wi-Fi Network
Your doorbell needs to be transferred to a different router or a new Wi-Fi name. For the wired doorbell, the new network needs to be 2.4GHz, with a visible name and WPA or WPA2 security.
Removing the doorbell from the app switches off alerts and recording until you add it again. Since your door is unwatched then, handle it when you are home and able to complete it. You may have to configure that doorbell’s settings again. First, save any clips you want to keep.
- Launch the Anker eufy app, select your doorbell, then access its settings. Check under “Settings” › “General” to find “Wi-Fi Connection”. Previous versions included a Wi-Fi setup screen there. Certain models and app versions no longer display it. If you locate it, input the new network name and password and stop here.
- When a Wi-Fi option is unavailable, delete the doorbell within the app and proceed to confirm.
- Tap “Devices” › “Add Device” and select your doorbell model. When selecting the wired doorbell, pick “Wired Doorbell”.
- Scan the QR code on the doorbell. For the wired model, hold the doorbell button until it dings.
- Select your network (2.4GHz for the wired doorbell) and type in its password.
The doorbell is back once it appears online and live view opens.
9. Transfer Eufy Doorbell to New Owner
If a doorbell remains linked to the previous owner’s eufy account, you might not be able to add it to a new account. Eufy offers no verified transfer guide, so rely on what the app displays, and reach out to Eufy support if the app prevents the new owner from adding the doorbell.
After the prior owner deletes the doorbell from their account, that account loses alerts and recording. Since clips might be unavailable later, make sure to save the desired ones beforehand.
- The new owner downloads the Anker eufy app and sets up an account.
- The prior owner retains whatever clips they wish to hold onto.
- The prior owner deletes the doorbell from their account, following entry 8, step 2.
- The new owner presses “Devices” › “Add Device”, selects the doorbell model and scans the QR code.
- The new owner links the doorbell to their Wi-Fi (entry 8, steps 4 and 5).
The transfer is complete once the doorbell shows up only in the new owner’s app.
10. Eufy Doorbell RTSP
RTSP (Real Time Streaming Protocol) is a standard method for sending a camera’s video to other software, like a home server or a recorder. Eufy confirms that the Video Doorbell Dual (Wired) currently lacks RTSP support.
Before buying any doorbell, check the specification sheet if RTSP matters to you. Should you still be picking a brand, the Blink Doorbell vs Eufy comparison details the contrasts.
11. Does Eufy Doorbell Work with IFTTT?
IFTTT (“If This Then That”) connects apps and devices through simple rules. Eufy’s help page covering third-party smart platforms indicates IFTTT is not supported for its doorbells, so you should not expect a ready-made connection. Verify which integrations your model displays in the app or on its product page. The Eufy and IFTTT guide explores the responses with greater specificity.
If nothing worked
Reach out to Eufy support. Find your model on the Eufy support site (new tab), which has articles for the wired doorbell and for other models, and use it to contact the support team for your region.
Before you write or call, have this ready:
- The doorbell’s serial number, found printed on the device itself or its packaging, along with its model (like E340, S4 T8215, Dual or hardwired).
- If you have a HomeBase, the color of its light.
- Word for word, any error message from the app.
- The “Voltage Diagnosis” test outcome, and the voltage shown on your transformer.
- The indoor chime’s make and model, if the chime is the issue.
- The precise time of a ring or motion event that didn’t trigger an alert.
Frequently Asked Questions
Do I need a HomeBase for my Eufy doorbell?
The answer varies by model. Your 2.4GHz Wi-Fi links directly to the Eufy wired doorbell, while the Video Doorbell S4 (T8215) is compatible with a HomeBase. For other models, see what the box or the app’s setup screen asks you to plug in.
How do I find my Eufy doorbell’s model number?
Look on your doorbell and its box for the model number. Since the wired doorbell, the Dual, the E340 and the S4 all follow different steps, give that number to support.
Why is there no sound in my Eufy doorbell recordings?
In the app, check your doorbell’s settings beneath “Audio Settings” and ensure that “Audio Recording” is enabled. Next, confirm your phone’s media volume is raised. If both are working, contact support with your model number.
