Ubiquiti UP-SENSE smart home multi-sensor Wireless Bluetooth Humidity Motion Temperature

The Ubiquiti UP-SENSE smart home multi-sensor measures humidity, motion and temperature and communicates wirelessly via Bluetooth. It is compact and lightweight, powered by a CR123A lithium battery, and designed for unobtrusive placement around the home. The sensor transmits environmental and motion data to compatible smart home systems and integrates with the UniFi Protect ecosystem, enabling automated responses, monitoring and simple status checks from connected devices.

Advantages

The UP-SENSE offers a combination of humidity, motion and temperature sensing in a single device, reducing the need for multiple separate sensors. Its Bluetooth wireless connectivity allows for installation without additional wiring, and the CR123A battery provides a long operating life suitable for remote or hard-to-reach locations. The small form factor and polycarbonate enclosure make it easy to place on walls, shelves or other surfaces while keeping a low visual profile. Integration with the UniFi Protect ecosystem enables centralized monitoring and event-based automation.

Suitable for

• Room environmental monitoring — tracking temperature and humidity in living rooms, bedrooms and utility spaces
• Motion detection for basic occupancy sensing and activity alerts
• Integration with UniFi Protect or compatible Bluetooth-based smart home systems
• Placement in cabinets, hallways, basements or other indoor locations where discreet sensors are preferred

When it may not be suitable

This sensor uses Bluetooth for communication, so it may not be suitable where long-range wireless coverage or mesh networking is required; range and reliability depend on the local Bluetooth environment and placement relative to receivers. It is battery-powered, so it may not be ideal for applications that demand continuous, high-frequency sampling without periodic battery replacement.

Key specifications

• Sensing functions: humidity, motion, temperature
• Wireless interface: Bluetooth
• Power source: CR123A lithium battery
• Enclosure material: polycarbonate
• Color: white
• Typical installation: indoor use, wall or shelf mounting

How to use

Install the CR123A battery according to the device instructions and position the sensor in the chosen indoor location, avoiding direct heat sources and areas with heavy condensation. Pair the UP-SENSE with your UniFi Protect system or another compatible Bluetooth hub following the hub's pairing procedure. Once paired, configure thresholds and alerts in the management interface to receive notifications for motion events and environmental changes. Periodically check battery level and sensor placement to maintain reliable operation.

What to consider before purchase

• Ensure your smart home hub or controller supports Bluetooth-based sensors and integration with the UniFi Protect ecosystem if required
• Confirm CR123A battery availability and expected battery life for your usage pattern
• Check that the intended placement is within Bluetooth range of the receiving device
• Verify indoor-only suitability and compatibility with your environmental monitoring needs

Usage recommendations

Place the sensor at typical room height away from direct sunlight and HVAC vents for representative temperature and humidity readings, and near entryways or activity areas for accurate motion detection. Regularly monitor battery status in the management app and replace the CR123A battery when levels run low to ensure continuous data and alerts.
