Note: It is not compatible with the original eufy Wi-Fi Chime (T8020), eufy Chime (T8740/T8742), or Apple HomeKit.

Is Video Doorbell C31 compatible with HomeBase 3?

Yes, it is compatible with HomeBase 3. This setup provides expandable local storage, enhanced AI functionality, cross-device features, and more.

Why is my doorbell not working properly after binding?

Ensure you have the latest app (version 5.0.22 or above) and check if the doorbell has received the latest software update.

Will Video Doorbell C31 support pre-record and 24/7 recording? Will my existing chime still work?

Yes, C31 supports pre-record and 24/7 recording functions when powered by a 16-24V transformer (bypass chime). 24/7 recording is unavailable with HB2/Minibase, so use Solo or connect it to HB3 to enable this feature.

Why does my doorbell still show low battery or a decrease in battery level even after being wired?

Using Existing Chime charges the doorbell slowly (6-7 days). High foot or vehicle traffic may still drain the battery. We recommend switching to “Bypass Existing Chime” mode.
