# TempPro TP350 TP357 Bluetooth Room Thermometer and Hygrometer

## At a glance

- The display shows temperature and humidity, with a backlight and a face-icon comfort indicator.
- The app is claimed to store two years of readings and export history as CSV.
- The listing says the app needs no user registration and claims monitoring over Bluetooth up to 80M away without obstructions.

## Pros

- On-device display plus app access gives buyers both an at-a-glance reading and remote monitoring within the claimed Bluetooth range.
- Two-year history and CSV export support reviewing room conditions over time.
- Tabletop, magnetic-back and hanging-hole options provide different placement choices.

## Before you buy

- The listing is inconsistent about identity: the title and manufacturer part number say TP350, while the model field says TP357. It also labels the colour as “Bluetooth”, which does not identify a colour. Confirm the exact selected model and finish before purchase. The stated dimensions appear under different dimensions fields, and range, accuracy and battery-life figures are manufacturer claims rather than independently verified measurements.

## In the box

- Thermometer hygrometer (Included)
- User manual (Included)
- 2 x 1.5V AAA batteries (Included)

## A good fit for

- People tracking indoor temperature and humidity in a bedroom, baby room or other indoor space.
- Buyers who want app access and a record they can export for later review.
- Those who want a small monitor that can sit on a surface or attach using the listed magnetic or hanging options.

## Less suited to

- Buyers who need confirmed identity and configuration without checking the listing, due to inconsistent TP350 and TP357 model information.
- Anyone needing monitoring beyond the stated Bluetooth range or a verified measurement standard.

## Customer feedback

Aggregate ratings are mostly five-star, but a notable minority are one-star, so overall sentiment is favourable without being uniform. Ratings alone do not explain what buyers liked or disliked, and they do not establish the accuracy, Bluetooth range or app performance of this model.

## Frequently asked questions

### Which model is this, TP350 or TP357?
The title and manufacturer part number identify TP350, while the model field says TP357. The listing does not resolve the difference, so confirm the exact model on the selected listing.
### Can readings be checked on a phone?
The product is described as Bluetooth-connected, with app monitoring claimed up to 80M away without obstructions. Actual range may depend on obstructions and conditions.
### Does it keep historical readings?
The listing claims two-year data storage and CSV export through the app. This is a manufacturer claim, not independently verified here.
### What batteries and mounting options are listed?
The stated contents include two 1.5V AAA batteries. The listing gives tabletop, magnetic-back and hanging-hole mounting options.
