Customer feedback highlights ease of installation, HomeKit connectivity and the built-in motion sensor. One customer reports door events registering in under a second, while responsiveness is also described as mixed. For buyers using these sensors for prompt door or window status, responsiveness matters, but the feedback does not establish a guaranteed response time or resolve hub requirements for remote functions.

Positive themes

Customers report easy installation.
Customers report that the sensor works well with HomeKit and appreciate its motion-sensing feature.

Mixed feedback

Responsiveness feedback is mixed. A customer reports events registering in under a second, but no consistent response time is established.

Frequently asked questions

Does this three-pack include a SwitchBot Hub Mini?

The explicit contents list names Contact Sensor 3Pack only. The title says to add a Hub Mini for Alexa compatibility, so do not assume a hub is included.

Can it send alerts when I am away?

The listing describes remote phone alerts when connected to a SwitchBot Hub. A hub is therefore needed for that use.

How close must the magnet be to the sensor?

The two parts need to be aligned, with a distance of less than 1.2 inches (30mm).

Can it trigger smart-home scenes?

The listing describes scenes through the SwitchBot app. It specifically requires a SwitchBot Hub Mini for the stated coming-home and leaving-home automation.
