Pair the device with the SwitchBot app via Bluetooth to view live readings, historical charts and exported data. If you need remote access or automation, connect the hygrometer to SwitchBot Hub Mini or Hub 2 to enable cloud storage, push notifications and control through smart assistants. Configure alert thresholds in the app for temperature, humidity, absolute humidity, dew point and VPD to receive notifications when values go outside your set ranges.

Usage recommendations

For reliable measurements avoid placing the meter in direct sunlight or next to heating/cooling vents. Use multiple meters to monitor different rooms and connect to a SwitchBot Hub for remote monitoring and longer cloud storage. Replace batteries when the app shows low-battery alerts and periodically calibrate the sensor if precise conditions are required.
