How long does the Aranet4 device store historic data?

The amount of stored historic measurement data depends on the measurement interval of the device:

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.

Hello.

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????

Thanks.

Hello,

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/

If it does not help, please contact support@aranet.com.

Hello,

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 ?

Best regards,

Antoine

Hello Antoine,

Current Aranet4 app version keeps 30 days of measurements history in phone memory. After 30 days, 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.

I feel that there should be an option to delete or at least hide incorrect readings. Try blowing into the device and see how much CO2 it will register in the minutes after that.

Hello Antoine,

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

Dear all,

We are glad to inform you that since some time, the data could be downloaded in the background.

This means that you no longer need to open the app once every few days.

But you have to keep the application running, don't unload it from background processes.
And make sure that 'Background data read' is on in the app settings.

You have to log in to reply.
