How to get the Lifetime storaged charged value? #118

Open gabrielpc1190 opened 2 years ago

I have an SPF 3000 TL LVM-24p. Grott works really well and I have realtime data on my Home Assistant. I love it!

But I'm missing a value. The Growatt integration for Home Assistant provides a value called "Lifetime storaged charged" I use this value to feed my Home Assistant Energy Dashboard, on the section that calculates how much energy goes from solar into the battery, is the only value that I use from Growatt Integration, because it's not available from Grott. For how much energy comes out of the battery I'm using "ebatDischarTotal" and it's perfect.

How can I get this value? Since I think the inverter must be delivering it to Growatt servers, it has to go trought grott first. I already checked all the values on this file and none of those is the one I'm missing.

I do not have all value expose yet for the SPF (on the todo list). But if look in the documentation I can not find it either.

These are the fields I see in relation to charge/discharge:

You can find al fields in this document (defined in input reg, starts at page 12). https://docplayer.net/199800433-Growatt-offgrid-spf5000-modbus-rs485-rtu-protocol.html

Sometimes the growatt site calculated fields but to be honest I do not see how to calculate this either. I expected something like Bat charge total - AC charge Total or something like that.

Maybe you see it. If I have to change (add fields to) the record layout please let me know.

Is this still a valid issue?
