Getting history data #18

Closed steff333 closed 4 years ago

steff333 commented 4 years ago

Im trying to read the history data with DB_REQ_HISTORY_DATA_DAY but can't get it to work. The reason is to get the daily sums for production, grid etc.

Did you get it to work? I checked for example
e3dc.sendRequest(('DB_REQ_HISTORY_DATA_DAY', 'Container', [ ('DB_REQ_HISTORY_TIME_START', 'Uint16', 0), ('DB_SUM_CONTAINER', 'None', None),]), keepAlive=True) but always only get errors back.

Can you help?

I can try, but it seems that it's an error in the format of the request, and I have no clue about those. I only know how to handle the low-level communication. How did you come up with this request?

Honestly, I tried to get access to the archive values - I'm missing a proper documentation from e3dc. Is there a better way to retrieve e.g. the total amount of production by day?

It would be rather dull to read the data every second and calculate something manually.

I think I fixed it and sent you a pull request for the python3 branch

Thank you very much for your contribution. #20 I already picked up your enhancements for e3dc-rest.
