Introducing the Onvis SMS2 Smart Motion Sensor, a sophisticated HomeKit-compatible device that transforms your home automation experience. This advanced motion detector goes beyond simple motion detection, combining thread-enabled connectivity with integrated temperature, humidity, and light sensors. Whether you're securing your home, automating lighting, or creating intelligent climate scenarios, the Onvis SMS2 delivers precision sensing with Apple HomeKit integration and end-to-end encryption for complete privacy.
Key Features of Onvis SMS2 Motion Sensor
The Onvis SMS2 stands out as a comprehensive environmental sensing solution. This device combines multiple detection technologies into one elegant package, making it ideal for sophisticated home automation scenarios. Here are the standout features:
Thread Connectivity: The SMS2 utilizes Thread technology for fast, reliable mesh networking. Thread connectivity ensures responsive automation triggers and seamless HomeKit integration, even if your primary WiFi network experiences interference.
Multi-Sensor Capability: Beyond motion detection, the SMS2 includes integrated temperature and humidity sensors. Monitor environmental conditions in real-time and trigger automations based on temperature thresholds or humidity levels, perfect for climate-sensitive areas like basements, bathrooms, or nurseries.
Light Detection: The SMS2 includes a basic light sensor that distinguishes between bright and dark conditions. Use this to create sophisticated automations-activate lights only when motion is detected AND it's dark outside, preventing unnecessary lighting during daylight hours.
7-Meter Motion Detection Range: The sensor provides a generous 7-meter detection range, effectively covering medium-sized rooms and outdoor entryways. Adjustable sensitivity settings allow you to fine-tune detection for your specific environment.
Apple HomeKit Integration: Full HomeKit compatibility with end-to-end encryption ensures all your motion data stays private. Create complex automations using the HomeKit app's powerful automation builder without relying on cloud services.
Technical Specifications and Environmental Monitoring
The Onvis SMS2 delivers professional-grade environmental monitoring capabilities. The temperature sensor provides accuracy within ±1°C, while humidity measurement ranges from 0-100% with ±5% accuracy. These specifications make it suitable for diverse applications:

The SMS2's comprehensive sensor suite enables advanced automations impossible with basic motion sensors. Combine motion detection with temperature thresholds to create smart climate control, or use humidity readings to trigger ventilation automations.
HomeKit Automation and Privacy-First Design
The Onvis SMS2 represents the pinnacle of privacy-focused smart home technology. Unlike cloud-dependent motion sensors, the SMS2 stores all activity records locally on your iOS devices. HomeKit's end-to-end encryption means Onvis servers never access your motion detection data or automation preferences. This privacy-first approach protects your household routine and personal information from potential breaches or data harvesting.
Thread technology amplifies this security advantage. By creating a mesh network between HomeKit devices, Thread eliminates dependency on cloud connectivity for local automations. When your primary WiFi experiences issues, Thread ensures your automations continue functioning reliably. For families concerned about data privacy and security, the SMS2 offers unmatched peace of mind.
Advanced Automation Capabilities: The HomeKit app's powerful automation engine lets you create sophisticated scenarios using the SMS2's multi-sensor data. Set a "Goodnight" scene that triggers when motion is detected after 10 PM. Create a "Welcome Home" automation that activates specific lights when motion is detected in the entryway AND the current time is after sunset. Trigger climate control automations based on humidity levels detected in humid basements or bathrooms.
Installation and Setup: Quick and Hassle-Free
Setting up the Onvis SMS2 takes just minutes. The sensor includes adhesive strips for flexible mounting on walls or ceilings, plus a traditional mounting bracket for permanent installation. No special tools or technical expertise required.
Installation Steps:
- Add the device to HomeKit using the HomeKit code printed on the back
- Position the sensor in your desired location (adhesive strips or bracket mounting)
- Customize sensitivity settings in the HomeKit app
- Create automations based on motion, temperature, humidity, or light conditions
- That's it-the SMS2 immediately begins detecting motion and environmental changes
The intuitive HomeKit interface guides you through the entire setup process. No separate app or account creation needed. Unlike many smart home devices, the SMS2 requires no WiFi setup-Thread handles all networking automatically through your HomeKit hub (HomePod mini, iPad, or Apple TV).
Versatile Usage Scenarios
The Onvis SMS2's multi-sensor design unlocks countless automation possibilities:
Home Security and Lighting: Motion-triggered lights activate instantly when entry points detect activity. Pair with HomeKit cameras for security alerts and video recording. The bright/dark sensor ensures lights only activate at night, saving energy during daylight hours.
Climate Control and Humidity Management: Temperature and humidity sensors trigger ventilation automations, activating exhaust fans when humidity exceeds thresholds. Perfect for bathrooms, laundry rooms, and basements where moisture control is critical.
Energy Efficiency: Create automations that turn off lights, adjust thermostats, or disable devices when no motion is detected for extended periods. The SMS2 helps reduce energy waste while maintaining comfort.
Pet-Friendly Automation: Set motion detection sensitivity to ignore small pets while still catching human movement. Combine with temperature monitoring to ensure pets remain comfortable when you're away.
Night Mode and Safety: Configure automations that activate hallway lights at reduced brightness when motion is detected at night. The light sensor prevents glare-inducing full brightness activation while still providing safe navigation.
Comparison with Other HomeKit Motion Sensors
The Onvis SMS2 offers exceptional value compared to alternatives. While basic motion sensors like Eve MotionBlinds cost $30-40, they provide only motion detection. The SMS2 adds temperature, humidity, and light sensors at a similar price point. Eve's Environmental Sensor costs significantly more while offering less comprehensive motion detection capabilities.
The SMS2's Thread support provides networking advantages over older HomeKit sensors. Thread mesh networking ensures reliable local automation execution even during WiFi outages. This reliability justifies choosing the SMS2 for critical automations.
For HomeKit users prioritizing privacy and comprehensive environmental monitoring, the Onvis SMS2 delivers unmatched value and functionality.
