Govee H5051 WiFi Thermometer Hygrometer

The Govee H5051 is a wireless temperature and humidity monitor designed for indoor spaces such as greenhouses, wine cellars, or general home rooms. It connects via 2.4 GHz WiFi or Bluetooth so you can view readings remotely through the Govee Home app on iPhone or Android. The unit includes a Swiss-made sensor and comes with three AAA batteries.

Suits remote monitoring

This sensor suits users who need phone notifications when temperature or humidity drift outside preset limits and who want up to two years of CSV exportable history. It is not for buyers who require 5 GHz WiFi connectivity, need continuous real-time uploads without the 10-minute sleep cycle, or want a device powered by mains electricity instead of batteries.

±0.54 °F accuracy across -20 °C to 60 °C range

The monitor measures temperature from -20 °C to 60 °C with ±0.3 °C accuracy and humidity from 0 % to 99 % with ±3 % accuracy. On-board storage holds 20 days of minute-by-minute logs; the app retains two years. The 10-minute WiFi sleep interval conserves battery but pauses live uploads, so rapid-change detection has a built-in gap.

Questions about this item

Does this thermometer need a 2.4 GHz Wi-Fi router to send alerts to my phone?

Yes, it connects only to a 2.4 GHz Wi-Fi network for remote monitoring and app notifications; 5 GHz networks are not supported.

Can I still read the temperature on the built-in LCD if my phone battery dies?

The unit has a clear LCD screen that shows current temperature and humidity locally, so you can check readings without the app.

How do I verify the sensor is logging data at the stated accuracy after I set it up?

Compare the on-screen values with a known reference; the sensor is rated at ±0.3 °C for temperature and ±3 % for humidity, and the app stores readings every minute for review.
