Import and Export meters are zero if there's no CT meters

[bbarabe]

Hi,

I run a dual 15k with exports but without grid meter. Installer didn't think it was necessary.... mostly true, but your code doesn't support that.

I looked at the log and made a few tweaks that seem to work. Code below. Sorry, should do a proper PR, but... yeah, sorry.

I tweaked it a bit by parsing more values:

if k in ("pvPower", "battPower", "gridOrMeterPower", "loadOrEpsPower", "soc",
         "gridTo", "toGrid", "existsMeter"):
    live_data[k] = v

and - changing the parsing to this:

# ----- Grid import/export -----
# Priority 1: Use meter readings if meters exist and have data
meter_a = self._safe_float(data.get("meterA"))
meter_b = self._safe_float(data.get("meterB"))
meter_c = self._safe_float(data.get("meterC"))
grid_net = meter_a + meter_b + meter_c
exists_meter = data.get("existsMeter", False)

if exists_meter and grid_net != 0.0:
    # Meters are installed and reporting non-zero
    if grid_net > 0:
        sensors["grid_import_power"] = grid_net
        sensors["grid_export_power"] = 0.0
    else:
        sensors["grid_import_power"] = 0.0
        sensors["grid_export_power"] = abs(grid_net)
elif exists_meter and grid_net == 0.0:
    # Meters exist but reading zero - trust it
    sensors["grid_import_power"] = 0.0
    sensors["grid_export_power"] = 0.0
else:
    # Priority 2: No meters - use flow direction flags
    grid_power_val = self._safe_float(data.get("gridOrMeterPower"))
    grid_to = data.get("gridTo", False)
    to_grid = data.get("toGrid", False)

    if grid_to:
        sensors["grid_import_power"] = grid_power_val
        sensors["grid_export_power"] = 0.0
    elif to_grid:
        sensors["grid_import_power"] = 0.0
        sensors["grid_export_power"] = grid_power_val
    else:
        # Priority 3: Explicit keys as last resort
        sensors["grid_import_power"] = self._safe_float(data.get("gridImportPower", 0.0))
        sensors["grid_export_power"] = self._safe_float(data.get("gridExportPower", 0.0))

Hey complete noob here. I’m having the same issue, where do I find the code that needs to be edited?

If you want to give it a shot, I've been working on a fork that fixes this, creates additional sensors for grid up, generator running, etc.. add integral sensors so the energy dashboard works without needing helpers, and allow setting work mode from HA so you can automate time of use, etc.

The repo is here: https://github.com/bbarabe/HomeAssistant_SolArk

You can "upgrade" to the version I've been running by doing a custom update.

• Developer Tools
• Actions
• Look for action Install Update (update.install)
• Targets: pick SolArk Cloud
• Check box Version: and set as this one: bf02be6
• Click Perform Action

This will install the version I have been running here. This will also generate an update notice in Settings, so it is very easy to go back by simply updating to the mainline one. Let me know if you hit any issue... I run a master/slave system so I couldn't test on a single box system.

[Adameastwoood]

Thaks for this, very much appreciate the clear instructions. I've updated successfully. But I'm getting this error:
"Failed setup, will retry: No inverters found for plant”

I assume this is something to do with the fact that you have a master/slave redundancy set-up where as we have a single box system.

Is there an edit I could do to the code that would allow a configuration with a single box system?

[bbarabe]

Yeah sorry about that. I just made a tentative fix - try this version: 33030f7

Although that particular error should be before I look for master/slave... Are you sure you've set the right plant ID?

[Adameastwoood]

Thanks very much for your help. I’ve now got a working system. My plant ID has a format ######/#. I’m sure on the original install I had to delete just the / but on this on i deleted the / and last number.

Thanks again, now to set up some automations!

[bbarabe]

Thanks for the update! Glad it works. So you are using my code and it resolved your issues? Let me know if you hit any bug - I'll want to send a PR at some point to share to others. Benoit.
