FAQ

Can it be used in the fridge or freezer?

Using the thermo-hygrometer in a refrigerator or freezer will shorten the battery life and affect the connection of the device in low temperature environments. The recommended ambient temperature for prolonged operation is 14–140°F (-10–60°C).

Can it be used in a high humidity environment for a long time?

Since the device is not waterproof, it is not recommended to use the device in a high-humidity environment (above 80% RH water condensing) for a long period of time.

How do I set the temperature and humidity alarm range?

Go to "Device Settings." Under the “Temperature Alarm" and "Relative Humidity Alarm" settings, select the temperature and humidity you want to track by moving the slider or choosing from the dropdown list.

How do I export data?

To export data, start by tapping on the thermometer hygrometer on the app's device page to access the data page. Once you're on the data page, scroll down to the bottom and tap the "Export Data" button. Keep in mind that you can only export a maximum of 6 months (180 days) worth of data at a time, so make sure the time span you select falls within this range. If you need to export data for the entire past year, you will need to do so in two separate batches.

How do I calibrate the temperature and humidity?

The device has been calibrated by precision instruments and usually does not require recalibration. If you still want to calibrate, you can go to "Device Settings" and calibrate the temperature and humidity in the “Calibration” setting.

How do I distinguish which device in the app corresponds to the real device?

The box your device comes in contains stickers. After you add a device to the app, label it by writing its name in the app and on the provided sticker and sticking it to the device. To distinguish, use the app's test feature. To test the device, go to "Device Settings" and select "Device Test." During the 10 seconds, the LED light during the test will remain solid blue.
