Download historical consumption data

[jeanmoulart]

Hello,

I've been using an ecodan asph for over two years but I've just been starting to measure the consumption of the heat pump with a separate meter recently.

I would like to know if there is a way to download historical consumption data that is stored somewhere in the system. I would then integrate it into Home Assistant.

I do not use MELCLOUD and I've got @F1p 's ESP32 Ethernet, running on the most recent stable firmware (6.3.5-h3).

Any help/advice would be appreciated !

Have you setup any helpers to measure computed energy figures, e.g. to feed into the energy dashboard?

[jeanmoulart]

Yes, I have an increasing consumption meter that measures global consumption, then I have set up utility meters for each purpose : heating, cooling, hot water and on hold. This is integrated in the energy dashboard. Is this what you mean by

any helpers

?

How long does the history on this increasing consumption counter go back?
I was wondering if you could use this for histrory

Otherwise it is default Home Assistant retention period, which you can overwrite in configuration.yaml

I think my question was not clear, I would like to pull the data from the ecodan asph system. I have access to historical data on my ecodan ftc6 controller, therefore it should be stored somewhere.

I would then find a way to push it into HA's energy dashboard but I need the data first.

Over the CN105 connector we get values for "yesterday" currently
I think the main controller keeps track of these and builds the running history for the month/year

[jeanmoulart]

Yes, but I do not have the full history from the "yesterday"'s value in HA. I seems there is no way to connect to the main controller and get back the daily values, those are maybe not even stored and aggregated as monthly/yearly values.
