Indoor climate monitoring

The TempPro TP-357 is a Bluetooth thermometer and hygrometer designed for indoor use. It measures temperature from 32 to 140 degrees Fahrenheit and humidity with stated accuracy of ±1 degree and ±2%. The device pairs with a smartphone app to deliver alerts and store up to one year of historic data graphs.

Home owners needing remote alerts

This unit suits anyone who wants to track conditions in a humidor, greenhouse, wine cellar or similar space without being on site. Buyers who require multiple sensors for different rooms or need a display that works without a phone should look at other options.

260-foot Bluetooth range

The connection reaches up to 260 feet without obstructions, which determines whether the sensor can communicate from the monitored space to your phone. Walls and floors will reduce the effective distance, so verify the layout before purchasing.

Questions about this item

Will the TP-357 sit on a shelf next to my older hygrometer without interference?

The TP-357 uses Bluetooth with a 260ft range and refreshes every 10 seconds, so it operates independently of any non-Bluetooth hygrometer you already own

How can I verify the TP-357 is reading correctly after I pair it?

Check that the LCD shows a face icon for DRY, COMFORT or WET and that the app graph updates every 10 seconds within ±1°F and ±2%

Does the TP-357 box include everything needed to start monitoring, or must I buy a sensor separately?

The package contains the thermometer body and batteries; no extra sensor is required to begin use
