Recalculate schedule on change of "EV target SOC" - not an issue at all as it calculates when the car is connected .... #223

I'm new to this - just added it yesterday so sorry if I’ve just not understood it properly and its a support issue and note a feature request :-)

We have gotten used to having a look at the electricity prices including a forecast for the following days. I.e. significantly longer than the prices are known. In HA I have EnergyDataService with Carnot forecast . But we are following https://www.facebook.com/elforbrug But basically if there is a lot of wind in the weather forecast the chance of good prices are good :-)

Our usage varies a lot. Some days 40% is more than adequate while we need 100% on others. So, we are used to having to set the target SOC manually depending on the need and the price forecast (So far that has been easier to just set the Target SOC than trying to automate it. The one that has the longest takes the EV while the other takes the ICE. So not easy to automate ......)

Opportunistic charging does not solve the issue of easily telling how much is needed, but looks like a good solution if you i.e. need xx% a day but would like to charge to yy% when the prices tomorrow are good.

I Assume that the charging schedule will be recalculated when the car is connected or when new prices are available.

But it would be nice with the visual feedback of a changed schedule as soon as you have changes the EV target SOC

The planned charge on top of the prices in a apexchart is very easy for all to understand and verify with a quick glance.

PS even though my car has a SOC available tough Skoda Connect their servers are not 100% reliable - So I expect that I will have to my own logic in-between that monitors it and report a "safe low SOC" when it has not updated for a prolonged time.

The car got home, was plugged in and i got the following schedule:

image SOC 35% Target 90% and 13.5% Rate -> 4,07 Hours -> Rounded up up 5 hours

If i knoe decide that 70% was enought for tomorrow it does indeed change the schedule right away.

So i just have ensure that the car is connected for the schedukle to be set.

So it was just my understanding that was lacking - as i this morning looked at a plan for late night after the car had driven away ...

I think the non-issue i saw yesteday was just that the schedule was not calculated before the next days prices are known.

Now the car is home early today but not connected

Seems like there is no issue anymore, so I will close this.
