Vampire drain: keep track of overall loss, ignoring any gain from charging cycles

[wishbone1138]

Confused by vampire drain reporting. It feels like it should be:

From drive state D-P to next drive state P-D where not charging or pre-heating?

However, the reporting behavior seems almost random for me.

Here is an example of my recent states:

However, the only one reported over 6 hours period is the time on 2/5:

I might say that the system is ignoring sleep time but then the 2/5 entry doesn't appear to make much sense.

I think I may have answered my own question. It appears that if there is a charging state at all during that time, then it will ignore that entire period? Is there any way to keep track of overall loss, ignoring any gain from charging cycles?

Yes, this is exactly how the current implementation or database query works.

Is there any way to keep track of overall loss, ignoring any gain from charging cycles?

We have the data for that. The query "just" needs to be modified accordingly.

Got it, I know it's not trivial, I've tried to calculate that myself in the past but my database fu is lacking. Would this be a better way of doing it? I can take a look if you, and others, agree.

Besides ignoring gain from charging cycles it could also be an option to stop monitoring once the heater goes on. Now if you preheat the car there's a rather high vampire drain due to the preheating of the car.

Somewhat related to to this issue; I'd like an additional graph showing overall vampire drain vs. driving usage similar to the AC vs DC charging comparison (x % vampire drain, y % driving). Not sure if this should be a new issue or integrated into this one?
