I think the formula miscalculates.
Your site data this day, 12-11-2021 21:55
My Home assistant data this day 12-11-2021 21:55
All sensor data is wrong.
I don't know what makes the difference, can you help what is the problem?
Thank you for your fast reply.
Hi,
In fact, this is because that home assistant seems calculate the first daily kwh as this formula.
the last kwh data of the first day - zero.
In fact,the proper formula should be the last kwh data - the first kwh data.
You can get the first and last kwh from this page in IAMMETER-cloud
You can find this passage here:https://www.home-assistant.io/integrations/utility_meter/
Note:
Sensors created with this integration are persistent, so values are retained across restarts of Home Assistant. The first cycle for each sensor will be incomplete; a sensor tracking daily usage will start to be accurate the next day after the integration was activated. A sensor tracking monthly usage will present accurate data starting the first of the next month after being added to Home Assistant.
