EZVIZ Doorbell Chime Not Ringing? Here’s How to Fix It

Step-by-step fix guide | EZVIZ cameras and doorbells

Try this first — Look at the CH1 chime’s light. EZVIZ’s CH1 manual says slow-flashing red means the Wi-Fi connection between the chime and your router has failed, and fast-flashing red means the connection between the chime and the doorbell has failed.

This guide is for owners of the EZVIZ EP3x Pro or HP3 Pro doorbell whose chime doesn’t ring. The steps come from EZVIZ’s CH1 chime manual, the two doorbells’ UK and global EZVIZ pages and datasheets, and the HP3 Pro manual.

What This Problem Means

The EP3x Pro and HP3 Pro can ring two kinds of chime: the EZVIZ CH1, a mains-powered chime that links to the doorbell over Wi-Fi, or an existing wired chime. EZVIZ lists the wired option as “Existed Mechanical or Electric Chimes (8-24V AC)”. If the CH1 loses its link to the router or the doorbell, its light tells you which.

Common Symptoms

  • The CH1’s light is flashing red slowly or quickly
  • Your existing wired chime doesn’t ring
  • You’ve fitted the HP3 Pro’s solar panel and also use a wired chime
  • You use the doorbell with Google Assistant and no chime sounds there

Safe Checks You Can Try

1. Check the chime works with your doorbell

EZVIZ’s CH1 manual says: “At present, Chime is only compatible with EZVIZ standalone battery-powered video doorbells like EP3x Pro.” EZVIZ’s HP3 Pro datasheet also recommends pairing it with the CH1 for large houses.

For a wired chime, both doorbells list “Existed Mechanical or Electric Chimes (8-24V AC)”. The HP3 Pro manual is more specific: it works with doorbell systems supplying 8-24 volts AC, 50mA, at 50 or 60Hz, 40VA max.

2. Check the CH1’s light

“Solid Blue” means the “Chime is functioning properly”. “Slow-Flashing Red” means the Wi-Fi connection between the chime and your router has failed. “Fast-Flashing Red” means the connection between the chime and the doorbell has failed. The full table is below.

3. Link the CH1 to the doorbell again

With the chime plugged in, wait for the light to flash blue quickly: EZVIZ says that means the “Chime is ready for Wi-Fi connection”. In the EZVIZ app, tap the + button on the home page and scan the chime’s QR code, then follow the app. The last linking step in EZVIZ’s CH1 manual is: “Choose the Doorbell you want to link to the Chime, and then tap Finish.”

4. HP3 Pro: don’t combine the solar panel and a wired chime

EZVIZ’s HP3 Pro manual warns: “The solar panel cannot be installed with the wired chime at the same time, otherwise the solar panel will be damaged.” Use one or the other.

5. Using Google Assistant? It has no chime function

EZVIZ’s global pages for both doorbells say that with Google Assistant you can watch live, but you “cannot receive incoming video calls or use the chime function”. EZVIZ’s UK pages for the two doorbells don’t mention Google Assistant.

Which Chime Each Doorbell Works With

Doorbell Chime options EZVIZ lists
EP3x Pro An existing mechanical or electric chime (8-24V AC), or the EZVIZ CH1 (not included with the doorbell)
HP3 Pro An existing chime on a supply of 8-24V AC, 50mA, 40VA max, or the EZVIZ CH1 (not included). Don’t use the solar panel and a wired chime together

If you’re not sure what your existing wired chime runs on, ask a qualified electrician rather than opening up the wiring yourself.

When To Contact Support

If none of these steps fix it, contact EZVIZ through EZVIZ’s support site.
