Sum entity production once every hour

Energy
1

Hey,

from my solar thermal system (warm water) I get an entity value “energy last hour” (unit is Watt per hour) It is a moving average value.

Now I would like to add up this value once every hour so that I can see how much energy the system supplied me with.

Is this possible with functions built into Home Assistant?

Thank you so much

Not really sure what you mean, but try using the ‘‘Utility’’ helper. I use it for measuring gas usage on daily base. You can setup reset intervals. Keep in mind you can’t see data right away in most cases. Can take up to two hours.
