## Description

The ThermoPro TP357 is a compact indoor Bluetooth thermometer and hygrometer designed to keep track of temperature and humidity across several rooms. It pairs with a smart app to log readings and send alerts, so you can spot changes early and adjust a humidifier, dehumidifier or heating accordingly.

## Key features

This three-piece pack offers simple comfort indicators that show dry, comfortable or humid conditions at a glance, making it easy to interpret indoor air without digging into numbers. The sensors are rated by the manufacturer as highly accurate with temperature and humidity tolerances that suit everyday monitoring, and the app presents historical graphs so you can review trends over time.

## Specifications

## Usage tips

Install one unit in each room you want to watch and keep the app notifications active to receive alerts when readings fall outside set limits. The two-year data view in the app helps identify seasonal patterns, which may guide adjustments to ventilation or humidification. Bear in mind that Bluetooth range can reduce through walls, so place sensors with this in mind.

The pack includes three ThermoPro TP357 sensors ready for Bluetooth pairing and data recording, suitable for baby rooms, offices and general home use. The easy-to-read comfort icons and app alerts aim to make ongoing monitoring straightforward and unobtrusive.
