Loosing stored data

[leakim1957]

I have v2.2.20 and last night at 01.00 all stored data both "Energy use last 24 hours" as well as "Energy use last 31 days" was lost, see picture. This is not the first time this happends. I remember at least two other occations after the HW was replaced in january.

Sounds like there could be some sort of edge case where this happens. Would have to look into that. Does your device have access to internet?

[leakim1957]

Hi Gunnar Yes, internet access 24/7. If there should be an internet drop out at some time, why would that erase the memory stored?

It shouldn't, but if it does not have internet access, it gets time from the meter which in some cases are not completely reliable, and if the time drift is too high, the data is cleared

[leakim1957]

Ok, I will check the connection. Can you specify the time drift, Is it seconds, minutes or hours?

[gskjold]

If the timestamp was suddenly in the past compared to last stored point in time, or if the time is more than 1day or 1month in the future respectively. But I think this is probably some other edge case that have caused this. As long as the device boots with a set timestamp, the time should not be an issue.

I've tried to find some way to reproduce this, but I have yet to succeed. Could you give me some more information:

Hi Gunnar See my answers below in red. I would like to add that I have only had data saved for a maximum of 5 days in a row for the past few months. Sometimes only 1 day, sometimes 2-3 days. ///Mikael BW

@leakim1957 That did not work well (we cannot see what is "red"). You need to log into Github and write your message there.

[leakim1957]

Hope this will be better:-)

Country: Sweden

@leakim1957 You closed the issue - was that on purpose, or was it a mistake?

OK - you are running a Pow-P1 on a Sagemcom in Sweden. We have several such installations running, I don't think the hardware is an issue.

Sounds more like some strange edge issue, probably related to other reports lately of missing/lost data. @gskjold is working on it, trying to recreate the issue.

[gskjold]

Got two issues regarding loosing data, both Sagemcom, do you know of any more cases @ArnieO ?

None other than those reported in issues here on Github.

[leakim1957]

It was a mistake, I am not used to work in github

[stigvi]

Some kind of issues with mine too. Uptime is 34 days, but only the last 19 have any data.

[gskjold]

Interesting indeed, something definitely happened here

Hi. I see from my Tibber App that 8th of August was rather special because my energy cost that day was NOK -1.90. I don't have any entsoe prices downloaded to my unit, so I am not able to see any connection to the missing data. But maybe there is?

[gskjold]

Good to think outside the box here, thanks for that. I am not able to see a connection there either, but will keep it in mind

[gskjold]

I finally understand what is going on here now, will fix this for next patch

[leakim1957]

Can´t wait to test it :-)

[senspix]

Possibly the same issue but with month plot. Also Sagemcom T211 device in Sweden.

[leakim1957]

Hi. Loading screen shot of system after installing latest version. Let´s see what happends with stored data as time goes by. ///Mikael

[leakim1957]

Hi, just when I hoped the problem was solved, it has appeared again. No problems since last update but tonight at 0200 it went blank and no update of prices either. ///Mikael

[leakim1957]

31 days in a row without loosing data. Well done!!! ///Mikael

[ArnieO]

So - let us hope this bug is dead and gone for ever now!
