Restore chart dont work

Dashboard
1

Hi,
I calculated the power from my solar panels with node watt2kwh and then bar-chart-data to get chart for hour, day and month. I stored the outgoing payload from my chart with contrib-persist and i can see all of the stored value. But the problem when i deploy and want to restore the values i recive zero because the last value wins and when i deploy the solar panels send a value so all of my saved data is overwritten with the last value. What are i doing wrong?

I also tried white storage ui write file and read file and same thing.

It is very difficult to tell without seeing your flows. OR any sample data.

What I will say though is, you'd be better off storing this kind of data in a database (that's what they're designed for)

Then, it would be a simple case of pulling the day/week/month worth of data from database when the dashboard is opened.

I cant show any data now because no value from solar panels right now. but i save the data on my raspberry pi you can see the flow here
