Battery export sensor incorrect

[jongbj1972]

Describe the bug

The battery export sensor indicates a battery discharge of only 3kWh/day while reality is approx. 12kWh/day

Expected behavior

correct data being read from the battery export sensor

Additional Context

Up until recently, the battery export sensor functioned fine, although, due to a database change, I cannot dettermine when it started to go wrong, but it is clearly visible that the data is not correct.

[WillCodeForCats]

If you look in the debug file look for the battery_id_1 section towards the bottom.

The sensor values for battery energy are:

        "B_Export_Energy_WH": "0x40806d",
        "B_Import_Energy_WH": "0x409e8b",

These are hex integer values, so a value of 0x40806d is 4227181 watt-hours, or 4227.181 kilowatt-hours

The integration does not interpret these values, they are passed through as given by the inverter. You would need to either download diagnostic files or watch debug logs to check if that value is increasing or not.

The data in the SolarEdge online platform is separate from modbus.

[jongbj1972]

So if I understand you correctly, the integration reads the values as presented by the inverter and only converts the HEX to numerical value. Then I appologize for sending in the bug report and will try to solve on the inverter side.

[WillCodeForCats]

Yes, that's correct. The value is displayed.

It checks other conditions but if it's showing a value that's the value it's getting from modbus. You can check the diagnostic files to see if the hex value is changing or not.

Concerning these two sensors (sensor.solaredge_b1_energy_import and sensor.solaredge_b1_energy_export) I see them unavailable (state = 'unknown') frequently. Reloading the integration kicks them again.

Edit: I checked the debug file. The file is showing correct data while the integration says Unknown. Then do a reload of the integration and the correct decimal data is showing.

Screenshots showing in the order they were made. Before:

After reloading the integration:

[richardambridge]

Did you find a solution for this? I see the same

I'm running off battery overnight, and the B1 Energy export level is not changing overnight

[jongbj1972]

No, according to the developer it is not the integration, so no, there is no solution. I doubt it is the SolarEdge software as the web-application shows the correct information.

[WillCodeForCats]

Download diagnostic files or check debug logs to see if the value of B_Export_Energy_WH or B_Import_Energy_WH is changing.

[MikeTango]

Hi,

i am having the same issue and will monitor the logfiles after it freezes, then reload and check the logfiles again Next chance to do that is tonight at 2200ish local which is the usual time it kicks out. .

[richardambridge]

With debug on, the values are not changing overnight, but I see the data in the solaredge app is changing.

although their website is showing 0W export for the time, but it does show battery dischange.

04.log

here is all the data for 04:xx hour: grep custom_components.solaredge_modbus_multi.hub home-assistant.log |grep " 04:..:.." > /tmp/04.log

[MikeTango]

Step 1: Screenshot, state unknown since yesterday 2200ish

Step 2: Activate logging Step 3: Reset Integration Step 4: Screenshot, state OK

Step 5: Download log Step 6: Deactivate logging

The first lines in the log :

2024-04-20 22:24:14.794 WARNING (MainThread) [pymodbus.logging] Failed to connect 2024-04-20 22:24:18.599 WARNING (MainThread) [pymodbus.logging] Failed to connect 2024-04-20 22:24:24.002 WARNING (MainThread) [pymodbus.logging] Failed to connect 2024-04-20 22:24:34.205 WARNING (MainThread) [pymodbus.logging] Failed to connect

Correspond well with the battery sensor death, although i don't know whether they are zulu time or local (+2). I might have screwed up the logging/resetting process since the log shows nothing about the integration restarting. It also starts timestamping after my screenshot. Do i need to download the log before restarting?

[WillCodeForCats]

So first off, all I'm really doing here is proving this is not a bug in the integration: the integration just takes values the inverter gives, does some validation and checks for obviously wrong or invalid states that would mess up graphs/statistics, and passes them into Home Assistant.

The SolarEdge app and monitoring platform is completely separate from modbus. If one of those works and the other doesn't, that's a bug in the inverter firmware that SolarEdge would need to fix. This integration can only use the data the inverter gives it over modbus. If the inverter keeps returning the same data every time it asks without increasing the values, that's an inverter bug and unfortunately there's nothing I can do about it except show you how it's not my problem to fix.

You could try power cycling your entire system to cold boot it (turn off all AC and DC safety switches) to see if that re-syncs everything. That's been reported as a solution in the past and is mentioned in known issues.

Battery energy sensors going unavailable can be several things which are already documented in known issues:

https://github.com/WillCodeForCats/solaredge-modbus-multi/wiki/Known-Issues

If you have battery energy going unavailable you probably have the "backwards" data issue and need to turn on some of the options that are designed to allow that. Home Assistant expects that energy meters should not go backwards, so if they do the sensors will go into unavailable state.

[MikeTango]

hi,i am running an original SolarEdge battery so it seems to be either something different or they have this problem with their own batteries now.

[WillCodeForCats]

Correspond well with the battery sensor death, although i don't know whether they are zulu time or local (+2). I might have screwed up the logging/resetting process since the log shows nothing about the integration restarting. It also starts timestamping after my screenshot. Do i need to download the log before restarting?

Yes because logs are cleared when Home Assistant restarts.

[MikeTango]

I restarted the integration only, there was no new boot info in the log.

[WillCodeForCats]

I'm not really seeing anything here that suggests a problem with the integration.

I don't have batteries on my system, so I can't give any advice on them.
