Attached I've added a snip of a graph where you can see the daily use and delivery of power in Watt.
In summary:
My opinion: The daily graph looks accurate, the weekly (with daily summary) is not.
If you look at the top right, for May 10th, I've delivered absolutely more than used from the grid.
Looking at the blue line, from 0:00, let's say 200W, for 8 hours is 1,6kWh used from the grid.
Now look at the 2nd bar graph which shows the daily sumary.
At the right side of this daily graph for "Woe" (which is the day above in the line graph)
According to the graph I would've used 5,15kWh from the grid (blue), and delivered back: 3,4 kWh (green).
For the blue graph the bottom light part displays 1,7 kWh, which could be the 1,6 kWh I estimated (8 hours x 200W)
The dark blue part is not correct, not sure where this is coming from.
The green part showing 3,4kWh delivered to the grid is definitely not ok. I would guess this is about 6 hours x 3kW = 18kWh
The panels generated today 34 kWh, minus the use of appliances, give or take, 18kWh could be okay, definitely not the 3,4kWh
The next few days I'll be monitoring the P1 meter data on the display by hand.
Does anyone else have a similar issue about the weekly bar graphs, not showing the correct daily summary?
btw, am I still correct a left-shift on a graph entry (for gas in my case) doesn't delete the entry, even though I need to confirm this with the popup?

I'm using an ESP8266 reading the P1 meter and sending each 10 seconds the data to Domoticz.
