Set up your eufy Video Doorbell C31 with Chime and pair the chime correctly. Follow this wiring and app guide to avoid common mistakes and fix chime issues.

Quick answer

To set up the eufy Video Doorbell C31 with Chime, first wire the doorbell to your existing doorbell transformer, then power the chime and pair both devices in the eufy Security app. Pair the chime before mounting the doorbell to avoid repeated removal.

Why wiring order matters for the C31

The C31 is a wired doorbell, so it draws power from your home’s doorbell circuit. If you pair the chime before confirming stable power, you may mistake a wiring problem for a pairing failure. Always complete the physical wiring and confirm the doorbell powers on before opening the app.

When the chime won’t pair

Most chime pairing issues come from distance or interference during the pairing window. Pair the chime in the same room as your Wi-Fi router, then move it to its final location. If pairing still fails, check that the chime is powered and within range of the doorbell. The C31’s 2K FHD camera and real-time chat features rely on a stable connection, so a weak signal can affect both video and chime performance.

Step-by-step setup and chime pairing

Prepare the wiring: Turn off power at the breaker before touching doorbell wires. Connect the C31 to your existing doorbell wiring according to the included instructions. Common mistake: leaving the breaker on—always verify power is off with a voltage tester.
Restore power and check the doorbell: Turn the breaker back on and wait for the doorbell to power up. The LED should indicate it is ready. If nothing happens, recheck wire connections before proceeding. If the doorbell does not power on, do not continue to app setup.
Download the eufy Security app: Install the eufy Security app on your phone and create or log into your account. Keep your phone close to the doorbell during setup.
Add the doorbell in the app: In the app, select Add Device and choose the Video Doorbell C31. Follow the on-screen prompts to scan the QR code on the doorbell and connect to your Wi-Fi network. Common mistake: entering the wrong Wi-Fi password—double-check it before confirming.
Power and pair the chime: Plug the chime into a power outlet near your Wi-Fi router. In the app, go to the doorbell’s settings and select Chime, then follow the pairing instructions. Press the pairing button on the chime when prompted. Common mistake: pairing too far from the router—keep the chime close during pairing. Pair the chime before mounting the doorbell to avoid removing it later.
Test the chime: Press the doorbell button and confirm the chime sounds. If it does not, check that the chime is powered and paired, and that the doorbell and chime are within range. Common mistake: assuming a silent chime means a faulty unit—try re-pairing first.
Mount the doorbell: Once everything works, mount the doorbell using the provided hardware. Choose a location with a clear view of the door area and within Wi-Fi range. Common mistake: mounting too high—aim for chest height for the best 4:3 view.
