Three-sensor Bluetooth pack

This pack contains three H5100 hygrometer thermometers that connect to the Govee Home App via Bluetooth. Each sensor measures temperature from -4 to 140 with ±0.54 accuracy and humidity from 0%-99%RH with ±3%RH accuracy. The app delivers instant notifications when readings move outside your preset ranges at up to 230 feet. Swiss-made sensors provide the measurement performance.

Works with H5151 gateway

Sensors pair with the optional H5151 Wi-Fi gateway to remove distance limits and allow remote monitoring from anywhere. A single gateway supports up to 10 sensors so you can cover multiple rooms or zones. Each unit measures 3.0988 cm by 6.8072 cm by 7.7978 cm, letting it sit in potted plants, vivariums or other tight spaces. Free cloud storage keeps 20 days of online history and two years of exportable CSV data.

Sustained monitoring capability

Continuous logging builds temperature and humidity curves in the app without gaps. The two-year export function preserves long-term trends for review or compliance records. Bluetooth range holds at 230 feet for local alerts while the gateway extends reach indefinitely. Yellow digital displays show current values at a glance during extended deployments.

Questions about this item

How long does the 20-day online data storage last before it overwrites?

The cloud service keeps 20 days of readings online; after that period the oldest points roll off while the 2-year export file remains available.

How much heat does each sensor add inside a small enclosure like a vivarium?

The units are passive Bluetooth sensors with no active heating element, so they add negligible warmth to the space they occupy.

Do I need the H5151 gateway to view readings on my phone?

No, the three sensors connect directly to the Govee Home App via Bluetooth up to 230 feet; the gateway is only required for Wi-Fi access beyond that range.
