Model: WSMS2
$20 – $30
Affordable wireless motion sensor with 120° detection zone, pet immunity, and 18-month battery life. Requires Wyze Sense Hub.
You want no monthly fees for basic alerts
Motion alerts and app notifications are free. Professional monitoring optional at $10/mo. No subscription required.
You need human-only detection (no pets)
Designed to detect people only, not pets. Reduces false alarms from cats and dogs. Good for pet owners.
You already use Wyze cameras and ecosystem
Seamless integration with Wyze Sense Hub. Triggers camera recordings. Works with Wyze app for unified control.
You want the cheapest home security motion sensor
One of the most affordable options at ~$8-10. Part of Wyze budget ecosystem. $10/mo monitoring is cheapest professional option.
You need reliable consistent detection
Many reports of sensors not detecting motion beyond a few inches. Detection range often far below 25ft spec.
You do not have Wyze Sense Hub
Requires Wyze Sense Hub (v2). Not compatible with v1 bridge. Cannot work standalone or with other platforms.
You want HomeKit or smart home automation
No HomeKit, Google Home assistant, or SmartThings integration. Wyze app only. No Matter support.
Detection range often 7-10 inches instead of 25ft claimed. Users must wave hand inches from sensor to trigger.
Wyze ForumFalse positives 5+ times per hour even on low sensitivity with no one home. Constant motion detected alerts.
Wyze ForumHub reset causes loss of all sensors and rules. Sensors may prompt for Cam Plus plan during re-setup.
Wyze Forum May 2024Hub shows online but sensors stop working. V1 and V2 sensors affected. Service outage in April 2024.
Wyze Forum April 2024Detection range far below 25ft specification
widespreadCause: Hardware or firmware issue. Many units only detect motion within inches.
Constant false motion alerts when no one home
commonCause: Sensitivity issues. Even low setting triggers 5+ false alarms per hour.
Hub reset loses all sensors and rules
commonCause: No cloud backup of sensor configuration. Must re-add everything manually.
Service outages affect all sensors
occasionalCause: Cloud-dependent system. When Wyze servers down, sensors stop working.
No HomeKit or cross-platform support
widespreadCause: Wyze ecosystem lock-in. No Matter or standard smart home integration.
Expecting 25ft detection range out of box
Motion not detected until within inches of sensor. Security gaps.
Tip: Test actual range before relying on sensor. Position closer to traffic paths if needed.
Not having Wyze Sense Hub before purchasing
Sensor is useless without Hub. v2 sensors not compatible with v1 bridge.
Tip: Ensure you have Wyze Sense Hub (not v1 bridge). Hub is separate purchase.
Resetting Hub without documenting sensor setup
All sensors and rules lost. Must re-pair and recreate all automations.
Tip: Document sensor names and rules before any hub reset. No cloud backup exists.
All functionality requires Wyze cloud. Alerts, app control, history, monitoring.
Very limited. Basic hub function may work but no remote access or notifications.
Motion events, timestamps, device status. Sent to Wyze servers.
Cloud-dependent. Wyze had data breach in 2019. All events logged to cloud.
Tested with up to 100 devices
120° FOV, 25ft spec range (often much less in practice). 18-month battery life. Human-only detection. Wyze Hub required.
Actual range often far below 25ft spec. Requires Wyze Sense Hub (v2). Cloud-dependent. Frequent reliability issues.
