Compatibility
| Ecosystem | Support | The catch |
|---|---|---|
| Amazon Alexa | Works | Live view on Echo Show |
| Google Home | Works | Live view on Nest displays |
| Apple Home | No | No Apple Home — eufy floated HomeKit but its own page still lists it unsupported |
| SmartThings | No | Not supported |
| Home Assistant | Partial | RTSP via HomeBase |
Protocols: WIFI
Subscription reality
✓ Works without a subscription: Yes.
No subscription — local storage on HomeBase or SD
Maintenance reality
- Batteries: built-in rechargeable — expect roughly 4 months per set
- Cloud dependence: No — core function survives without the vendor's cloud
- Dual-cam design; local storage means YOU manage retention
The catch
No Apple Home — eufy promised HomeKit but its own product page still says it's unsupported; treat it as an Alexa/Google doorbell.
Who it's for
For buyers who want dual cameras (face + package view) with no monthly fee and local storage.
