Dual Connectivity Monitoring

The GEEVON-LINK GL-250T13-1-WH-WUS is a two-pack Wi-Fi and Bluetooth thermometer hygrometer built for home kitchens, fridges, freezers and tubs. It connects directly to 2.4 GHz Wi-Fi without a separate gateway and pairs via Bluetooth for local setup. Temperature accuracy reaches ±1 °C or ±1.8 °F with humidity at ±5 % RH, while the external probe delivers ±0.25 °C from -10 °C to 50 °C and ±1 °C outside that range. All readings flow to the Smart Life app for remote access.

Flexible Placement Options

Each unit includes a waterproof probe on a cable plus suction cup, double-sided tape, lanyard and cable tie so you can mount the sensor inside a freezer or aquarium while the main body stays outside. The probe withstands -40 °C to 120 °C for liquid and extreme environments. Power comes from two included AAA batteries per device, and the low-power microprocessor extends runtime with an app alert when voltage drops. No wiring or external hub is required for operation.

App Data and Voice Control

The Smart Life app stores one year of history and lets you export records for review. Custom high and low thresholds trigger instant push alerts for temperature, humidity and battery level. Integration with Alexa and Google Home enables voice queries and automated scenes such as switching a dehumidifier or AC when conditions cross your set points. 5 GHz Wi-Fi is not supported.

Questions about this item

How long does the probe cable let me reach into a deep freezer?

The external probe cable measures 250 cm, giving plenty of length to route the sensor deep inside a chest freezer or refrigerator compartment.

Does the unit heat up or make noise when it runs continuously?

The thermometer uses an energy-efficient microprocessor and two AAA batteries, so it produces no audible noise and negligible heat during all-day operation.

What must I already have at home for the Wi-Fi features to work?

A 2.4 GHz Wi-Fi network and a smartphone with the Smart Life app are required; 5 GHz networks are not supported.
