Works With
The SimpliSafe 4-pack Entry Sensor is a solid, no-frills choice for SimpliSafe users seeking reliable door and window monitoring but falls short for those wanting broader smart home compatibility or advanced features.
The SimpliSafe 4-pack Entry Sensor is designed to monitor doors and windows for unauthorized openings, integrating primarily with SimpliSafe's own security system. It excels in providing straightforward, reliable intrusion detection with a simple design and decent wireless range. The sensors are compact and unobtrusive, making them easy to place on most entry points. However, a notable limitation is that these sensors are largely tied to the SimpliSafe ecosystem, limiting flexibility if you want to integrate them with other smart home platforms like Alexa or Google Home. Setup is typically quick, but users report occasional issues with sensor alignment causing false alarms. Battery life is decent, usually lasting around 1-2 years depending on usage, but replacement requires removing the sensor. This pack is perfect for SimpliSafe system owners who want to secure multiple entry points without fuss. It’s less suitable for those looking for multi-platform compatibility or advanced features like tamper alerts or environmental sensing. If you want a sensor that works seamlessly with a broad smart home setup or offers more customization, you might want to look elsewhere. Overall, it’s a solid choice for basic entry monitoring within the SimpliSafe ecosystem but has clear trade-offs in flexibility and advanced functionality.

Ecosystem
Easy to install on every type of door or window. The magnet goes on the door or window, and the sensor goes on the frame (or vice versa). Magnet can be placed up to 2 inches from the sensor, so sensors fit on all types of doors and windows. SimpliSafe sensors come with the battery pre-installed and adhesive tape pre-applied, making set-up a snap.
Connectivity
Requires Hub
SimpliSafe Base Station
Only works within SimpliSafe ecosystem; no support for major smart home platforms or protocols.
Compared to the Ring Contact Sensor, SimpliSafe’s entry sensors offer a more straightforward setup but lack Ring’s deeper Alexa integration and more frequent software updates. The Wyze Entry Sensor is cheaper and supports broader smart home platforms via IFTTT, but its build quality and battery life tend to be inferior. Samsung SmartThings Multipurpose Sensor offers more features like vibration and temperature sensing, but it’s more complex to install and generally costs more. SimpliSafe’s sensors stand out for simplicity and reliability within their own ecosystem but fall short if you want multi-platform support or advanced sensor capabilities.
Installation difficulty rates around 2 out of 5. Setting up each sensor generally takes 5-10 minutes, requiring only basic tools like a screwdriver or adhesive strips included in the package. The process involves pairing sensors with the SimpliSafe base station and mounting them on doors or windows. Most users find the instructions clear, but alignment is crucial to avoid false alarms. Professional installation is usually unnecessary unless integrating into a larger security system.
Users report reliable daily performance with minimal false alarms when sensors are properly aligned. The response time to the base station is typically under one second, which is adequate for entry detection. The SimpliSafe app is straightforward but somewhat basic compared to competitors, lacking advanced customization options. Battery life is generally good, lasting up to two years under normal use, though replacing batteries requires removing the sensor. Some users note occasional connectivity drops in larger homes without signal extenders.

Homeowners looking for a reliable and simple security solution.
Ensure you have a SimpliSafe system for full functionality.
Buy this sensor pack if you already own or plan to get a SimpliSafe security system, as integration is seamless. Avoid if you want sensors that work with multiple smart home platforms. Pair with SimpliSafe’s base station and consider adding signal extenders if you have a large home. Be careful during installation to align sensors properly and reduce false alarms.
