Description:
This compact ThermoPro Bluetooth hygrometer combines remote monitoring and a Swiss-made sensor to keep tabs on temperature and humidity in rooms like nurseries, greenhouses, offices and cellars. It updates readings frequently and includes a backlit clock and comfort indicator, helping you spot uncomfortable conditions at a glance while receiving alerts to changes that matter.
Key Points
The device links to the ThermoPro Sensor app via enhanced Bluetooth with a quoted range up to 80 m or about 260 feet in open spaces. The integrated Swiss sensor provides higher accuracy than many basic units, with temperature tolerance around ±0.5 °C and humidity around ±2% RH according to the manufacturer. Readings refresh every 10 seconds, which is useful if you want near real-time tracking of environmental shifts. The screen shows time and date along with a three-level comfort indicator that displays DRY, COMFORT or HUMID, so you can assess conditions quickly without opening the app. You can set temperature or humidity thresholds in the app and receive instant push notifications if values move outside your chosen range, allowing prompt action to protect plants, stored goods or a baby’s room. The app stores historical data and offers free cloud storage for up to one year, letting you review trends over periods such as 24 hours, one week or 12 months.

Advantages
Having both a local display and app connectivity makes the TP358 flexible. The backlit LCD lets you read values in dim rooms, while the comfort icon simplifies interpretation for quick checks. Notifications via the app reduce the need for constant manual monitoring and can help prevent problems such as humidity-related mould in cellars or stress to sensitive plants. The inclusion of longer-term data storage means you can spot seasonal patterns or recurring issues without exporting logs manually.
Usage Recommendations
Place the sensor away from direct sunlight and heat sources for the most representative room readings. For greenhouse use, set slightly different comfort thresholds to reflect plant requirements rather than human comfort. In a baby room position the unit at breathing height but out of reach, and use the notification feature to alert you if humidity or temperature moves into ranges you want to address quickly. Consider that Bluetooth range may be reduced by walls and floors, so test placement to ensure reliable connectivity within your home or building.
