Data storage error after turning off the device

I have saved a few data while using bolt IOT and LDR but after I have switched it off and turned it on again my data was lost. Why the data wasn’t saved as they showed me in the video lecture

Hi @rohankhera13,

Click on the data download button and check if the data is present in CSV file. On graph page, by default is shows only six hours of data. If you want to see the older data, change the time from dropdown.

Do let me know in case you need any other information,
