Keeping an eye on temperature and humidity in different rooms can be tricky. The ThermoPro TP350 makes it easier.
We tried this Bluetooth hygrometer and thermometer around our home. Setting it up was simple, and we could track changes remotely with its app.
The backlit display helped us read info even in darker rooms. The app connection worked well up to about 260 feet, which was pretty impressive.
Usually, it gave us accurate readings, though sometimes humidity levels took a moment to update. Having two sensors in different spaces gave us a clearer picture of our home environment.
If you want a handy way to monitor temperature and humidity without juggling multiple devices, the TP350 is a solid pick. It’s easy to use and connects well to your phone.

Overview of the ThermoPro Hygrometer Thermometer for House TP350
Setting up this device was a breeze. We used it around the house to track temperature and humidity with good accuracy.
It sent data to our phone via Bluetooth from a decent distance. The backlit screen is bright enough for dark rooms, and the comfort icons quickly show if conditions are good.
The app stores data for up to two years, which really helps if you like tracking changes over time. We liked using it in places like the nursery and gym.
However, the two-pack feels a bit bulky sometimes. Occasionally, the Bluetooth connection needed a moment to sync.
Pros:
- Easy app control without sign-up
- Long data storage and export
- Clear backlit display
Cons:
- Bulkier than some models
- Occasional Bluetooth lag
Key Features
After using this device for a while, we found it handy for keeping tabs on temperature and humidity without being right next to it. It’s great for bedrooms or greenhouses where you want precise environmental info.
App Control up to 260FT
The app let us check conditions from up to about 260 feet away, as long as walls didn’t get in the way. We liked not needing to sign up, which felt safer for privacy.
The connection stayed stable during our tests. We could rely on real-time updates on our phones whether we were in another room or outside.
Two-Year Data Storage and Export
The long data storage stood out. It keeps logs for two years—handy for tracking changes over seasons.
Exporting the data was simple, so we could spot trends and adjust things like heating or humidifiers ahead of time. This feature is a plus for anyone who likes to pay attention to how their indoor environment shifts over time.
High Accuracy and Fast Sensor Response
The sensor refreshed data every 10 seconds or so. We found the temperature readings matched other trusted devices.
Humidity levels stayed consistent, which made it reliable for baby rooms or spots with sensitive equipment.
Backlit Display with Comfort Indicator
The display is easy to read thanks to the backlight, even in dim light. The comfort icon gives a quick visual clue about air conditions.
We found ourselves glancing at the icon for a fast check instead of reading the numbers every time.
Versatile Usage Across Different Environments
This device fits in lots of places—bedrooms, baby rooms, even gyms or greenhouses. The ability to monitor temperature and humidity remotely through the app made it easy to check conditions in separate rooms.
In cooler spots like basements or cigar rooms, it helped us keep humidity in check to prevent damage. The clear display and backlighting mean it’s readable anywhere.
In really big spaces, the Bluetooth range can feel a bit limiting. But for most rooms, it adapts easily from home to more specialized environments.
Installation and Setup Experience
We had a pretty smooth setup. The device arrived ready to use, battery included.
Connecting via Bluetooth to the app took just a few steps—no account needed, which was a relief. The display lit up fast, and the backlight helped us check readings in darker rooms.
Sometimes the app needed a moment to update, but the connection stayed steady within its range. The setup guide was simple, but we found the app instructions helpful when syncing multiple units.
Instructions for mounting were a bit limited, but the compact size makes it easy to place on most surfaces. Overall, it felt user-friendly and didn’t take much effort.
Pros and Cons
We noticed several features that make this device practical for everyday monitoring. Still, there are areas where it could improve.
Pros
- Easy Remote Monitoring: We liked checking temperature and humidity from far away using the app. It worked well up to 260 feet.
- Long Data Storage: The two-year history and export option helped us track changes over time.
- Accurate and Fast Readings: The sensor responded quickly and showed consistent numbers. Comparing two units side by side, the readings matched well.
- Clear Display: The backlit screen made it easy to read values in dark rooms. The comfort icon gave us a quick sense of conditions.
- Versatile Use: We found it handy for lots of rooms—plants, musical instruments, baby rooms, you name it.
Cons
- App Limitations: The app doesn’t require registration (which is good for privacy), but it feels a bit basic or limited sometimes.
- Battery Life Could Vary: The battery usually lasted long for us, but it depends on use and settings. Some folks might need replacements sooner than they’d like.
- Accuracy Isn’t Perfect: For very precise needs, like scientific measurements, the small margin of error (+/- 0.9°F and +/- 2% RH) could be an issue.
- No Multi-Unit Sync: The sensors work well alone, but there’s no easy way to link multiple units in one app view for whole-house monitoring.
Customer Reviews
We saw that people appreciate how reliable and consistent the TP350 is for tracking temperature and humidity. Many mention its helpful app and long battery life, which makes monitoring simple over time.
The device works well in different spaces, from homes to greenhouses—even RVs. Some customers pointed out minor downsides, like occasional questions about exact accuracy and the need to position the sensor correctly.
Most agree the readings are close enough for everyday use.
Key points from reviews:
- Pros: Easy to use, good battery life, helpful app integration
- Cons: Slight doubts on perfect accuracy, placement affects readings
After spending some time with the ThermoPro hygrometer, I’d say it’s both reliable and practical for keeping an eye on indoor temperature and humidity.
I really like the Bluetooth feature—it makes tracking data feel almost effortless. The battery lasts a long time, which is always a relief.
It’s easy to use and blends in nicely whether you put it in a bedroom, office, or even a greenhouse. Still, if you’re after super-precise readings, maybe look elsewhere.
For most people, though, the ThermoPro lands in that sweet spot of accuracy and convenience. It gets the job done for everyday home use, and honestly, that’s usually what matters most.
