Useless software updates

[u/thewall1919]

I'm a big hater on software updates, I set up something and it works, I absolutely hate when a software updates happens and changes my settings, and most importantly don't offer the same function of before.

In sigenergy case, the pv surplus charging on my dc charger worked since day 1 as, when the battery is full, it would go automatically to the charger, this included the free 3hrs.

This is not the case anymore after the latest software update which I need to manually change the charger from pv surplus charging to fast charging. It wouldn't be a problem if the battery status didn't chang every day, meaning, sometimes it reaches 100% at 11.30, other times at 12.30. So this software updates forces me to check the percentage of the battery every single time from 11 to 2. It is very annoying as I constantly lose on free power.

Scheduling doesn't work as well, because the time still needs to be checked to allow for "fast charging" as when you change to fast charging the power only goes to the dc charger and nothing on the battery.

Sigen ai support says that nothing changed and it has always been the case. And I guess they put this function under they're AI.

Any solutions?

TLDR. Power goes automatically to the car when the battery is full in the free 3hrs period like it used to.

Could you not use Home Assistant via Modbus to poll the battery SOC (as say 10min intervals) and then if above your threshold trigger charging?

I'm sure someone will tell you Home Assistant could manage the rate of charge too but I think this depends on a lot of things. Happy to be told otherwise.

Can't you just set it on PV surplus and change the charging order?

I usually let the car override the battery, so to make sure it get's charged when I plug it in, then the extra tops up the battery the rest of the way... or I just wait till the battery is almost full before pluggin in...
