AIO constantly discharging 600w when GE EV charging.

I was under the impression GE had "fixed" the draining battery when charging technical issue.
I have AIO, gateway, GE EV charger.

currently setup to run the house/AIO/EV from the panels not grid (no export mpan yet)

When my EV was super flat, i needed to use octopus intel go to fill the car overnight, but the battery went weird.

As you can see from the first picture which is a normal night my draw is 100-300w with peaks of a few kw when my immersion heater kicks in.

The second picture is when i charged the car, the charger is set to 10a for a slower charge, but it makes no difference if i set it higher, the draw from battery is always the same about 600w
The other oddity is my 3kw peaks from the immersion heater are gone, there are a few bumps.

Either way, my AIO usually drops 20-25% overnight, this time, nearly flat in the morning! sad times.

The third pic is the same night charging, but gateway view.. and on there, the immersion heater peaks are visible, the real house load minus charger is visible, and you can see its pulling from the grid to charge the car etc.

Is this a reality of how things work, setup problem, or install problem?

Is this even with the “Prevent Battery Discharging to EV” option enabled?

Thankyou for the reply, yes all the photos provided are with that option turned on.

I have stopped using the app as it sometimes does things you’re not expecting. I have set the EVC up in the cloud and it works very well. This is what I have set up in the section I think you mentioned. If you need my other settings please let me know and I will screen shot them.

My advice (after trying it) set it up in the cloud, then look at the app to see what the settings are there. I found they were different, however GE have just updated the app so this may have changed in Android, I use IOS.

Thankyou for your input. I have tried a mix of settings but those are identical to mine currently, for some reason the battery just seems to think house load is 600w anytime the chargers on. Very odd.
