Bluetooth thermometer hygrometer
Thermopro TP357
Best Bluetooth thermometer hygrometer – Budget – 0 $ to 25 $
The THERMOPRO TP357 is our Budget pick for tracking temperature and humidity around the home without a complicated setup. Buyers praise its useful app, quick readings and compact form. It suits everyday room monitoring, including kitchens and other spaces where you want trends on your phone.
Why this is the budget choice
The TP357 earns the Budget place by covering the essentials without making setup a project. Amazon buyers repeatedly describe it as easy to configure and useful in daily home monitoring. They also value the phone app for following temperature and humidity over time, rather than checking the small device screen only when they pass it. Compared with the higher ranges, this is the straightforward option: compact, simple to place, and focused on basic readings plus Bluetooth tracking.
Choose the THERMOPRO TP357 if you want an inexpensive indoor temperature-and-humidity sensor with a phone app and a small footprint. Buyers praise its quick readings, simple setup and useful history graphs, and one buyer says it has worked for two years with Bluetooth working at least 15 metres. That combination makes it our Budget choice for ordinary room monitoring. Buyers are divided on accuracy and Bluetooth reliability: some report precise readings and a strong connection, while others report readings they do not trust or repeated connection problems. One buyer also reports unusually short battery life.
Who it’s for For home users who want simple room monitoring, app-based trends and a discreet sensor rather than a larger display or a more advanced system.
What sets it apart
- Easy setup and straightforward everyday use, according to Amazon buyers.
- The app helps track temperature and humidity over time with history graphs.
- Its compact size works well on a counter or in a small indoor space.
- Several buyers report accurate, quickly updating readings and useful Bluetooth monitoring.
What to know
- Amazon buyers are divided on accuracy; some report precise readings, while others say the temperature or humidity is off.
- Bluetooth feedback is mixed, with some buyers praising the range and others reporting recurring connection failures.
- One buyer reports replacing the battery after about two months.
- Some buyers report that the screen is small and the type is very small.
What the app adds
The main advantage over a basic screen-only hygrometer is the app. Amazon buyers say it lets them follow measurements on a phone and see temperature and humidity trends in graph form. One buyer used the sensor while proofing dough and found the phone view convenient for watching indoor conditions. The TP357 therefore makes more sense when the trend matters, not just the current number.
