Frequently Asked Questions

How do I connect the Holyiot Logger L1 to my smartphone and start logging data?

Download the official Holyiot app from your phone's app store. Enable Bluetooth on your phone, power on the logger, and open the app. The device should appear in the scanner list—select it to pair. Once connected, you can configure logging intervals, view real-time sensor readings on the dashboard, and access the history tab to review or export stored data as a CSV file for analysis.

What is the expected battery life of the Holyiot L1 logger using the CR2450 cell?

Battery life depends heavily on the configured sampling interval and Bluetooth connection frequency. With a moderate logging interval (e.g., every 10 minutes) and minimal app connections, a standard CR2450 battery can typically last several months. For maximum longevity, minimize the frequency of active Bluetooth data streaming and use the lowest practical sampling rate that meets your data resolution requirements.

Can the Holyiot L1 operate and log data in environments below freezing?

Yes, the Holyiot L1 is specifically rated for operation from -40°C to +60°C, making it suitable for freezer monitoring, cold storage, and outdoor winter conditions. The sensors and electronics are designed to maintain specified accuracy across this full range. Note that battery performance may decrease at very low temperatures, which should be factored into battery replacement schedules for critical applications.

How do I access the historical data stored on the logger's internal memory?

Historical data is accessed via the companion mobile app. Ensure your phone's Bluetooth is on and open the app while near the logger. After connecting to the device, navigate to the 'History' or 'Data' section within the app. Here, you can scroll through timestamped records and typically find an 'Export' or 'Share' button to send the full dataset as a CSV file via email or cloud storage for further analysis in spreadsheet software.
