Value energy are different netatmo_custom and netatmo_web_site

Hi
I have seen over several days that comparing the values reported by HA and the one obtained on https://home.netatmo.com/control/dashboard they were different.

On the web site i can see :

• Total : 24,73 kWh
• Reste : 10,39 kWh
• Piscine : 6,02 kWh
• Appareils de cusine : 4,06 kWh ( Plaque : 3,04 kWh and Four : 1,02 kWh)
• CE : 3,48 kWh
• PAC : 0,77 kWh

But, on HA i have zero consumption on hourly intervals and the total is lower.

In detail, I also have deviations and negative values

• Total : 19,27 kWh
• Reste : 7,35 kWh
• Piscine : 5,96 kWh
• Appareils de cusine : 3,8 kWh (Plaque : 2,78 kWh and Four : 1,02 kWh)
• CE : 1,53 kWh
• PAC : 0,63 kWh

Some days (like 7 october) I have several kWh in negatives, knowing that I do not produce any electricity.

In advance thank you for your answers

What''s the source of your "Total" measure ? On my side, I also have some negative values and, as I understand it, it comes from the way Netatmo data are saved. It seems consumption is gathered every 30 minutes at hour:15 and hour:45 whereas my Total consumption (not coming from Netatmo) is gathered every hour at hour:00 (which seems quite logical to me). The 15 minutes offset between "Total" and "Individual devices" explains the negative values. In fact, I don't understand how Netatmo can give a precise HC/HP amount if their hourly intervall begins at hour:15 whereas HC/HP switch is at hour:00...

The totol is from Netatmo and the total is identical to that of my electricity supplier (EDF). I have a high rate on Monday, Tuesday, Thursday and Friday and low rate on weekends and Wednesday.
What’s strange, when I look at my pool, it consumes 1 kWh, so I will have to have 6 histogram of 1 kWh during the 6hours that it works (this is what I see on the site https://home.netatmo.com/control/dashboard and the application Netatmo). However on HA, I see only 3 histograms, each showing an average of 2 kWh.
