no ideas :(

I have similar issue - suddenly the HA after update to 2024.7.2 shows negative values for charger: image

Presl1983 commented 4 months ago

you have to change the sensor - total energy should work now.

sanchosk commented 4 months ago

It's a sealed device from go-e, not sure how I can reverse some sensor myself. I thought it can be done in code.

syssi commented 4 months ago

As soon the root cause is known a fix is probably easy but I must admit I didn't understand what's causing the issue.

Presl1983 commented 4 months ago

image i took the total energy - you think that doesn't work?

sanchosk commented 4 months ago

So, I took the same sensor, it was working for more than year no problem, but since 2024.7 release starts to report minus values for some reason.

syssi commented 4 months ago

@sanchosk Which firmware version do you use?

sanchosk commented 4 months ago

56.8, go-e 22kW flex, charge controller firmware version 0.0.1-50

syssi commented 4 months ago

Do you have any idea when you started using this firmware version? Just to make sure we have to search the root cause at Home Assistant 2024.7

sanchosk commented 4 months ago

Long time ago - more than 2 months, so the FW version was not updated recently. The only thing I am aware of getting update recently was the HA version bump and the related problems with DB cleanup...

sanchosk commented 3 months ago
So, it seems the problem is with charger, not with HA. Today, I managed to track the issue. In my HA statistics, I can see following data: id state sum metadata_id created_ts start_ts last_reset_ts human time

At around 16:40 my wife arrived and plugged in the car. As of that moment, the state and sum column made a mistake - it seems the WH value is reset and started to count from 0. This caused HA to "rewind" the data back and consider there was huge negative value - in this case -37kWh of "return back".

Is it possible there is some firmware bug that "forgets" to send also the date reset or something?

sanchosk commented 3 months ago

@syssi Is it possible I am using wrong value for HA energy dashboard? I just noticed there are 2 different indicators - one called "Charged energy" that seems to reset with every new charging session. But there is another one, called "Total energy" and this one seems cumulative. The thing is, I did not change any setting, I am using this sensor long-term in HA. And there was no update to the integration, nor to my charger. My only explanation is that this is something that broke during 2024.07.02 release. Ideas?

syssi commented 3 months ago

Please use the total energy sensor (API key eto) and give it another try!

sanchosk commented 3 months ago

I did, surprisingly, HA already had the long-term stats for it even though it was not previously on the dashboard. Thanks!

syssi commented 3 months ago

Did this resolve your issue? Do you still expect a bug here?

sanchosk commented 3 months ago

Yes, I am about to close the issue. Thanks!

sanchosk commented 3 months ago

Turns out I cannot close it :( Can you, please, help?
