Understanding energy CSV output and tryingt to calculate energy usage

[Halono007]

I went to insights and then showed last 24 hours for my measurement of a heater (EVA Zigbee Smart Plug 16A plug ).
The report this for some measurements on energy usage (watts)

Example snip from output:

2023-08-21T19:35:00.000Z	4.42
2023-08-21T19:40:00.000Z	3.75
2023-08-21T19:45:00.000Z	861.83
2023-08-21T19:50:00.000Z	1894.68
2023-08-21T19:55:00.000Z	1906.23

Is this the total watts per 5 minutes? I wonder because the numbers don’t add up when I try looking at last 24 hours. The sum then becomes extremely large and it cannot be right. Maybe there’s an app to show this correctly?

Nice. however it seems really chaotic when adding all devices a second time just to monitor power usage.
