Besides open and close it detects motion and ambient light, runs 3 years on two AAA cells against 2 years, costs less and, through a SwitchBot Hub, reaches Apple Home, Google Home, Alexa, SmartThings and Matter. The Eufy Entry Sensor is the better liked of the two for a narrower job: inside a eufy Security system its HomeBase lets a door set off sirens, chimes and camera recordings with no monthly fee. Both work with Home Assistant, both need their brand's hub for remote alerts, and both are indoor sensors. Choose the SwitchBot Contact Sensor for flexible automations across platforms, and the Eufy Entry Sensor if eufy cameras and a HomeBase already guard the house.

What the differences mean

Extra sensors

The SwitchBot Contact Sensor also detects motion and ambient light, so one device can switch on a hallway light only when it is dark and someone walks through. The Eufy Entry Sensor reports open and closed only.

Platforms

With a SwitchBot Hub, the SwitchBot reaches Apple Home, Google Home, Alexa, SmartThings and Matter. The Eufy Entry Sensor works with none of those and reaches only Home Assistant beyond eufy's own app.

The hub each one needs

The Eufy Entry Sensor needs a eufy HomeBase for anything at all. The SwitchBot works over Bluetooth in its app without a hub, but remote alerts and every voice assistant need a SwitchBot Hub.

Security integration

Through the HomeBase, the Eufy Entry Sensor can arm with home, away and night modes and set off the HomeBase and camera sirens with no subscription. The SwitchBot has no siren or alarm modes of its own; it sends alerts and runs automations.

Battery

SwitchBot rates its sensor for 3 years on two AAA cells, easy to find anywhere. The Eufy Entry Sensor is rated for 2 years on a less common CR123A.

Which one to buy if

What owners say

Owners of both sensors describe fast, reliable alerts and an easy stick-on install, and both groups learned that the sensor depends on its brand's hub. Eufy Entry Sensor owners single out how it ties into eufy cameras, sirens and chimes with no subscription and a CR123A cell that lasts years; they complain about no HomeKit, Alexa or Google support, an app that can break after updates and a flimsy magnet housing. SwitchBot Contact Sensor owners single out getting contact, motion and light in one cheap unit and a smooth Home Assistant setup; their complaints are that remote access and voice assistants need a SwitchBot Hub, that Alexa only sees the contact function, and that the adhesive can let go in deep cold.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
