Product description

Waterproof Design IP65-rated main unit resists water splashes, making it suitable for wet environments such as pools, bathtubs, or kitchens without compromising performance.
Wide Temperature Range Equipped with a 1.5M 304 stainless steel probe for accurate readings from -40°C to 115°C, ideal for measuring in refrigerators, ventilation ducts, fermentation bottles, and more.
Real-Time LCD Display Clear, high-definition LCD screen shows current temperature instantly, so you don’t need to check your phone every time.
App Monitoring & Data Export View live temperature data and historical charts via the app, or export temperature logs for analysis and record-keeping.
Flexible Installation & Zigbee Connectivity Works as a Zigbee sub-device (requires Zigbee hub), with magnetic or hanging mount options for easy placement in different locations.
Customers find the temperature sensor works well with Home Assistant and other platforms like Hubitat and SmartThings, and appreciate its accuracy and battery life. The device is easy to set up and provides alerts when temperatures drop below set points, making it perfect for freezer monitoring. While the magnetic connection receives mixed feedback, with one customer noting it’s not strong enough.
