Home Manager 2.0 consumption data?

[ziogref]

I have an SMA home manager 2. I know it uses Speedwire over my local network (Ethernet) to communicate with my Inverter (Also Ethernet) So my consumption data actually appears in in my inverter (as seen here https://imgur.com/uQZyEqk ) from the screenshot you can see this is late at night and the inverter remains powered on 24/7 logging usage.

The home manager 2.0 doesn't have a web UI as much as I can tell, but the inverter can see import/export and generation and from that can work out self consumption. All that info is then available in the app and Sunny Portal website.

Is there a way for SBFspot to get that information to upload to PVportal?

side note: Devs you are fantastic and thanks for helping me with me issue prior.

As I explained to @g-mocken in this discussion, it might be possible recent inverters have some unexplored tables.

I don't have a Home Manager nor an Energy Meter, so my tables are empty, but if you want to test, here is how to proceed:
For the test we will (mis)use the ArchiveDayData function (this is the one used for the 5-min historical data)

Open the source file ArchData.cpp and locate the ArchiveDayData function (it's the very first one)
Find the line writeLong(pcktBuf, 0x70000200); (around line 93) - This is the command to get the 5-min data for a certain period.
The other known commands are 0x70100200 for Events (ArchiveEventData function) and 0x70200200 (ArchiveMonthData function) for Totals per day.

Now, I tried two extra functions 0x70300200 and 0x70400200 who do return valid data. The next two 0x70500200 and 0x70600200 do return only one record.

So for the test, you only have to change the line to writeLong(pcktBuf, 0x70300200); or writeLong(pcktBuf, 0x70400200);
Rebuild the program with make sqlite and run it. Remember: we modified the ArchiveDayData function, so the -adxx is important here (xx = number of days to retrieve)

When this actually works I can include this in the program. I expect the first command to return 5-min consumption data and the second probably total consumption per day.

I'm looking forward to the results and I'm sure this would be a really nice extension to SBFspot

Important remark: since we modify the ArchiveDayData function, make sure to use -nosql or test with a new or copy of your database.

@ziogref Sorry, I had no opportunity yet to get to my PC (and I was looking for a way to contact you privately). I'll post everything here as soon as I can

@ziogref This is my SMA-EM configuration. You have to fill in the fields with format ${identifier} with the appropriate values.

Hey, im getting errors with the sma-daemon and it looks like im not the only one. would it be possible to get your copy of /opt/smaemd?

It looks like the daemon is calling an empty variable.

@ziogref I remember SMA-EM causing some problems with my setup, too. But I just checked, the unit file points to /opt/smaemd/sma-daemon.py and this file does not have any changes.

rats. I am trying home assistant again and seems to be able to pull in the data from the inverter and I am writing custom sensors to get the data I want, so hopefully I can get it working

@ziogref
Q: the device with serial number xxxxxx0822 is that your Home Manager?

Yes it is (Home Manager 2)

If I interpret the above discussion correctly, experiments on consumption data retrieval were successful. What else is missing to make the data show up in the consumption tables?
If there is more to test, let me know (sorry for being late to the party). I have an SMA Energymeter in place of the HomeManager, though.

Hi @sbf- , is there something I could do to help with this enhancement?
