Smart Sensor for Cold Storage

The Emerson H5108 is a Bluetooth temperature sensor designed to monitor freezers, refrigerators and similar cold-storage environments. It ships with a probe, magnetic holder, lanyard and adhesive tape for flexible placement. The unit runs on a single included AAA battery and shows readings on a built-in LCD display. Data can be viewed in the GoveeLife app when the sensor is within 197 ft of a phone or paired gateway.

Home and Light-Commercial Users

The sensor suits households wanting alerts when a freezer drifts out of range and small labs or food-service sites that need two years of cloud-logged history. It is not for buyers who require an on-device audible alarm, because the H5108 only pushes notifications to the app. It is also not for installations that demand Wi-Fi connectivity without purchasing the separate H5151 gateway.

±0.9 °F Accuracy and 197 ft Range

The probe measures from -40 °F to 158 °F with a stated accuracy of ±0.9 °F (±0.5 °C) and refreshes every two seconds. Bluetooth range reaches 197 ft in open air; beyond that distance a compatible gateway such as the H5151 is required for remote monitoring. The anti-false-alarm delay can be set between one and ten minutes to ignore brief door openings.

Questions about this item

Do I need to buy the H5151 gateway to use this sensor with my phone?

The H5108 connects directly to the app via Bluetooth up to 197 ft; the H5151 gateway is only required for remote monitoring beyond that range.

Can I keep my existing GoveeLife sensors and add this H5108 to the same app?

Yes, the gateway supports up to 10 sensors simultaneously, so the H5108 will work alongside any compatible sensors you already own.

How do I confirm the ±0.9°F accuracy is working after I install the probe?

Check the LCD display for a reading that matches a known reference thermometer within ±0.9°F and verify the app shows live updates every 2 seconds.
