Old decoder value still there after removed when enabled Data storage

[chihao-feng]

Hi all!

I have added Data Storage Integration in my Application
I wrote some code in the decoder to show a “test” value and then I removed it
But because “Data Storage” will record the history payload
The “test” value still exist, like this:

does anyone know how could I remove the “test” value?
I already tried removing the “Data Storage Integration” and add it again but the “test” value still exists…
Please help me…

Best regards
Chihao.

You can’t, but: TTN Console’s Data page only shows a short history from that integration, like about an hour or so?

Even after that few hours, when no longer visible in TTN Console, it will still be kept for 7 days. Even removing the device won’t help, and after 7 days the device will still be returned (without data) by that integration:

@johan

The retention of 7 days is on the data, but we also store the number of stored messages per device per hour and this data has no retention. We don’t display this now, but the idea is that we might show you device activity per hour in the future, with a longer history than 7 days.

Aside: in one of your tests you returned test: "123". Whatever will be processing your Decoder’s result may expect a true number, which would show without the quotes in TTN Console.

It should already not show in TTN Console much earlier. See also Why application data is shown as historical?

Yes, It disappears after a weekend.
Thank you!
