How long does the Aranet4 device store historic data?
Posted: 02.07.2020 17:42
The amount of the stored historic measurement data depends on the measurement interval of the device:
Measurement interval, minutes Historic data availability, days 2, 5, 10 7 1 3.5

What happens after the amount of the stored historic measurement data is reached? Aranet4 will no longer store/share new data or oldest data will be deleted? Does it happen automatically?

The data that is older than the possible storage period will be automatically overwritten in the device memory with the new measured data.

How comes that Historic data availability is the same for 2,5 and 10 mn intervals? Couldn't it be 7,17 and 35 days?

Consider this as a product feature: historic data availability is the same for 2, 5, or 10 minutes measurement intervals configured.

My new Aranet4 device has just been in service for a little over a week. I noticed today though that the data collection ceased after 7 days (was running a 2 minute sample frequency). It has not actually continued to collect data and overwrite older days beyond a trailing 7 day window.
Up above in this thread there was a comment from aranet-techsupport stating:
"The data that is older than the possible storage period will be automatically overwritten in the device memory with the new measured data"
I am not finding this to be the case and can't seem to find any setting to resolve this. Seem to have to resort to manually pulling the battery every 7 days to refresh the data collection. Am I missing something????

A possible reason is your Aranet4 app is stuck. Please try to restart the app. If you are using iPhone, the following topic might be helpful: https://forum.aranet.com/all-about-aranet4/aranet4-application-measurement-does-not-update-with-new-data-from-device-the-app-displays-measurement-in-gray/

When I first launched my Aranet4, it created a huge peak of CO2 (more than 4000ppm) in the graphics displayed on my iphone. This was certainly a fake "very first" measurement. The problem is that this peak doesn't disappear (is not overwritten by new data) after one week, knwing my interval setting is 1 min. (so it should have been overwritten after 3.5 days if I understood well...). And this peak is so high, that it "crushes down" the real data on the display. I did fully restart the app several time, but nothing change. So, please, how to get rid of this initial peak on the data display ?

Current Aranet4 app version keeps 2 weeks measurements history in phone memory. After two weeks the data will be overwritten or you can reinstall the app to clear the history.
And thank you for reporting, manual history clearing will be included in the list of future improvements.

Thank you a lot for the quick answer!

By the way, you can clear the history of the measurements by deleting the sensor from the app and pairing it back again.
