PVOutput (input) interface shows only info every second day

[cvvt]

I use the PVOutput for several years with no issues so far.

However since a month, the "Generate last month" graph only shows data every second day.(see attachment)
On the PVOutput website, everything looks fine.

The value shown seems to be the sum of 2 days.

Any idea what can be the root cause ?

Any help is appreciated.

Do you have hourly values? In the other graph?

Dear RNEE,

Thanks for your reply.

Yes I have, see attachment.

FYI : i have 2 systems ( 2 groups of solar panels ) and both shows the same problem.

Which version of DVBAnalyzer are you using? The latest beta version?

Since 11 August, there has been made a change , requested by a user, to remove the from/till API variables when polling

https://github.com/domoticz/domoticz/co ... 7022094c9a

It could be related to this.

Are you able to code/test this function by adding this back in, or shall I create a new version so you can test if this solves the issue?

As I don't use PVOutput myself, I was not able to test the above change, but I received back that all worked out perfectly by the requested user.
It could be very well that this change is causing the issue you have right now

I have exact the same issue with pvoutput, both on my own domoticz installation (updated to 2025.1) and on the domoticz installation of my parents (they used version 2024.4 till yesterday). I think the issue isn't the changed API call in the last version of domoticz ((Fix #6371), because my parents have this problem since august 2024 (when they used version 2024.4) till now. And the problem consists in 2025.1. To reproduce the issue, I enabled the PVoutput (input) hardware yesterday on my own domoticz installation and I have the exact same problem as described here and what I see at my parents home.
When I look in domoticz.db, on one day there is no record from the PVoutput device and on the next day it counts up to the total of 2 days. So on the first day, nothing is registered in domoticz.db (not even a null value). It worked great till August '24 at my parents home. Maybe this information is of any help?

I can't change the code myself and am willing to try a version without fix #6371. But I don't think that is the solution. Probably something has changed in PVoutput or Domoticz in August '24 that triggered this issue.

Thanks for clearing this up!

Is it possible to contact me on our slack channel?

I would like to do some testing ...

Has anyone already figured cause and / or fix ? Only just noticed exact same behavior since August 3rd.
Appreciate your feedback !

[gizmocuz]

Could it be August 11th?

https://github.com/domoticz/domoticz/co ... _Input.cpp

I am running a test with someone else his API key...
Made an change/update today because it was missing the return data (latest beta)

In this test, at 15.00pm I see a huge pike of 13 kW... for one hour... that's strange!

If you are able to debug and help, that would be great.

Last accurate daily value displayed in Domoticz was for August 1st.
August 2nd onwards all daily values are incorrect. Actually daily values are 0 since then...every...day.

As per the Domoticz logs can see the PVOutput (import) is reading the counter values (totals) from PVOutput correctly and are updating correctly:

So as per my understanding the hourly generated values are no longer updating/calculated correctly (must be a calculated field right ?)

Screenshot 2025-11-06 160429.jpg (49.37 KiB) Viewed 57 times

Most likely something simple to resolve if you know the inner workings of the Domoticz DB. Which goes for most IT problems Easy to fix for a subject matter expert.
As am not a Domoticz SME and only using it for the monthly totals which are still accurate and ultimately can go to PVOutput interface as well I am just gonna leave it for now.

Thanks for your feedback though. Really appreciated !
