- Requires calibration out of the box for accurate results.
- Batteries need regular monitoring to maintain connection reliability.
Setting up the Govee WiFi Thermometer Hygrometer in our greenhouse was straightforward. The companion app paired effortlessly with our Wi-Fi and immediately started providing real-time updates. We appreciated being able to check conditions anywhere using the app, which made monitoring much more convenient than regular manual checks.
The accuracy of this device stood out. With its responsive Swiss-made sensor, we could confidently track even small fluctuations in temperature and humidity. This precision proved critical during weather changes when maintaining just the right environment was crucial for our plants.
However, we did have to calibrate the unit before use, which might be a minor inconvenience for some. Additionally, since it only works with a 2.4GHz network and relies on battery power, you will need to ensure your setup supports these requirements. Despite these small limitations, it has become an indispensable tool for keeping our greenhouse thriving.
3. ThermoPro TP350 Hygrometer
This reliable hygrometer is a smart investment for anyone needing precise greenhouse monitoring.
Pros
- Easy app-based control with no registration required
- Accurate readings updated frequently
- Saves long-term data for tracking trends
Cons
- Limited visibility in dark spaces without external lighting
- Bluetooth range can be impacted by heavy obstructions
- Compact size may be less noticeable in larger setups
We love how simple it is to keep tabs on temperature and humidity with the ThermoPro TP350. Using the app feels seamless, and the privacy-first approach—no registration needed—is a refreshing perk. The ability to export and analyze data also sets this device apart for more detailed planning.
The refresh rate impresses us; updates every ten seconds keep us informed about sudden environmental shifts. While its small design works well for discreet monitoring, it’s easy to overlook in sprawling greenhouses. If visibility is a concern, you’ll have to rely on a flashlight or nearby light source to make out the backlit display clearly.
For a Bluetooth-enabled device, the range performs reasonably well, but thicker barriers can dampen its connectivity. Even so, its accuracy and functionality make it a dependable addition to our sensor lineup.
4. ThermoPro Bluetooth Greenhouse Thermometer
For anyone managing a greenhouse, this sensor provides reliable monitoring with helpful app integration.
Pros
- Easy setup and straightforward app interface
- Highly accurate readings with fast refresh

Cons
- Bluetooth range is reduced with obstacles
- Requires a smartphone to view data
- No on-device display for quick checks
We tested this ThermoPro model and found it to be incredibly user-friendly. Pairing it with the app took only a couple of minutes, and we appreciated that batteries were included in the package—a thoughtful touch. The app itself offers a clear display of temperature and humidity levels, along with historical data tracking, which is a great feature for long-term monitoring.
As for accuracy, it consistently delivered precise readings every time we compared it with other devices. The fast 10-second refresh rate meant we always had up-to-date information. Its small size and built-in hanging loop made it easy to place inside the greenhouse, where space is often at a premium.
The main drawback is the lack of a built-in screen. Having to pull out a phone for every reading isn’t ideal, especially in busy moments. Additionally, while the Bluetooth range promises 260 feet, we found walls and other obstacles reduced this distance. Still, it’s a solid option for greenhouse owners who prioritize app-connected convenience.
