Govee H5103 WiFi Thermometer Hygrometer
A capable WiFi humidity monitor with a handy screen; watch battery life and the 2.4GHz requirement.
The short version
- People who want phone alerts when a basement, nursery or storage room gets too humid, hot or cold
- Anyone who likes a readable screen on the device as well as app history
- Your home WiFi is 5GHz only
- You want to read the display in the dark
- You need solid Home Assistant or other third party integration
- You don't want to change batteries a couple of times a year or more
What owners like
- Quick and simple setup
- Phone alerts and remote checking are the main reason people buy it
- Readings are seen as accurate for the money
- Trend charts make it easy to spot humidity swings in basements and crawlspaces
Common complaints
- Batteries need replacing more often than expected for some owners
- WiFi range falls short when the sensor sits far from the router
- Alerts can be unreliable at temperature extremes, or so sensitive they get noisy
- The screen is hard to read in a dim room because it has no backlight
- Most features depend on the Govee app, and third party smart home support has been patchy
Based on The Amazon listing, the full product description on a retailer page, an owner feedback summary at TestMarket, and two GitHub issue threads from Home Assistant integration projects..

What it does
A small indoor temperature and humidity sensor from Govee with an e-ink screen that also sends readings and alerts to your phone over WiFi and Bluetooth.
- E-ink screen shows temperature and humidity on the device itself
- Readings sync to the Govee Home app over WiFi, so you can check from anywhere
- Set your own temperature and humidity ranges and get a phone alert when readings go outside them
- Charts and up to 2 years of data you can export
- Swiss made sensor, per the product description
- Runs on three AA batteries rather than a wall plug
A sensible pick for anyone who wants to watch a basement, nursery, wine closet or grow space from their phone and still see the numbers at a glance on the device. The trade-offs are battery life that some owners find shorter than the stated six months, a 2.4GHz only WiFi connection, and a screen with no backlight.

Questions
Does the Govee H5103 work with 5GHz WiFi?
No. It connects only to 2.4GHz WiFi networks, along with Bluetooth.
How long do the batteries last in the Govee H5103?
Govee's description says about 6 months on three AA batteries. Some owners report shorter life, especially with a weak WiFi signal.
How accurate is the Govee H5103?
The stated accuracy is ±0.54°F (±0.3°C) for temperature and ±3% RH for humidity.
Can I export data from the H5103?
Yes. The Govee Home app stores up to 2 years of readings and lets you export them.
Does the H5103 work with Home Assistant?
Support has been unreliable. One integration's GitHub thread found it missing from the Govee API, and another reported values scaled wrongly in 2024.
