Hi Erwin thank you to awnser my question, I understand that trend a value of energy consumption in one oh our... I don’t need the addition of a day, I need the kWh consumption every hour in a year period. Thx!

Hi,

That’s exactly what a counter trend does, just try one then you see what i mean.

It only shows the (calculated) power used (difference) in every hour.

You can extract this hour usage data with trend.fetch when you want to report something.

Hi,

Is there a way to have the trend resolution larger than 1 hour, like 24 hours or even weekly/monthly?

Just look on the Trend app and you will see it on right side. All this is there out of the box.
