Higher electricity usage when solar in operation and batteries used

[andyrozman]

So I installed smart plugs all over house and Shelly Pro 3EM to monitor higher loads and lights. While I usually have around 60-100 W un-accounted for, when solar is in progress that Unknown number raises (its around 210)... I was wondering if this 100 W additional are batteries and inverter operating power... If yes, are this values visible somewhere (so that I could add them into HA and exclude them from my Unknown sources)?

Take a look at the parameters pcsActPwr and pcsMeterPower in the history. I always had a difference in these parameters. It seemed to me that the PowerOcean's own energy consumption was reflected there, because my household energy consumption was higher even after installation.

According to support, the self-consumption is already factored into the household energy consumption. A firmware update was just installed by support because the smart meter values ​​apparently weren't updating correctly. The difference isn't as significant for me at the moment, but it's still there.

Summing up pcsActPwr and sysLoadPwr seems only to produce meaningful values when discharging from battery.
When drawing from the grid the values don't make sense.
Not sure about when the power comes from PV because it's dark right now 😅

I imagine that you would have to account different scenarios... I am currently running of battery, my sysLoadPwr is 315.0 W (sysGridPwr is -1.0 W) and pctActPwr is 255.45. difference between sysLoad and pctActPwr is 59.55. Which would make sense that this difference is amount that inverter/battery uses ATM. If sysGridPwr was bigger that a whisper (I call 1-3 W import/export whispers, because you don't really import or export anything..) we would have to take into account that. When Solar is working there is DC-AC conversion happening so it would make sense that inverter would use more energy for himself then (and that unknown energy spikes during high solar production)...

@niltrip Would it be possible to make option to "take a snapshot/export current data", which would mean copy all values from current sensors into json file and open save dialog so that you could save this data (something similar to what happens when you disable debugging option). It would help us analyse thing like this much easier... I mean we are doing "educated" guesses on hand of just few sensors (that we decided to take a look at)...

You can export data easily from the history view. No need to build something I think 🤔

[andyrozman]

Sorry. I am in my first 4 months of using HA, so I have no idea how to do that... I tried to look it up in history tab, but don't know how to use it to see all the values from some point in time. Selecting ecoflow itself is showing only diagnostic sensors. Am I missing something?

[Xygen]

No worries!
In the History view just add the sensors and select a time range, click the 3-dots and select "download data".
You could also do that from the EcoFlow portal, but you'll get an Excel file from there. And not the same sensors as from HA...
