What to know before buying

Listing details to confirm

Compatibility claims name E340, C31 and C30 and exclude other eufy doorbells at this time. The listing also says upcoming eufy video doorbells will work, so future compatibility is not confirmed. It says the chime uses 2.4 GHz Wi-Fi and that a microSD card is not included and must be installed in the doorbell for footage storage, while product-detail fields list 128 GB storage and camera/video specifications. Those storage and camera details are inconsistent with the chime-focused description and should not be treated as confirmed chime capabilities. The title says it is not compatible with HomeBase S280.
