Offline Charging sessions - Missing Added Energy + Default Charge Type

[donok1]

Is there an existing issue for this?

• I have searched the existing issues

What happened?

At home (geo-fenced defined location) the car is parked and charged in an underground garage without internet connection.
The charge session are correctly identified in duration and location, but I have two recurrent issues:

1. Every few charging session, the amount of total added energy cannot be calculated and is left blank, although the before and after SOC are correctly identified. Additionally, when it calculate the added energy, it often show a lower amount than effectively charged.
   For the second charge on the screenshot below, 23% -> 100% should add up to at least 43 kWh (for my 56 kWh battery, not counting charging losses).
   Anybody has an idea why that could be ?

2. The charging session are recorded as DC, while it is actually AC charging. As it is offline, teslamate cannot know which type it is.
   Is there a way to add a default charge type to a Geo-Fenced location to cover the case of offline charges ?

And here a log of the past 3 charges: teslamate_log_25-11-2024_charges.log

charged in an underground garage without internet connection

Without internet connection, no data got populated to the API and TeslaMate is not able to retrieve any information

Therefore, the charge is not logged.

As soon as your car get internet connection again, TeslaMate recognize the new SOC and try to do its best to fit in the values, but the charging sessions was never populated to API and is lost, therefore the values can not be accurate.

I understand that the API is an available, and not data during the charge is to the expect.

As I understand, commit 1317588 back in v1.6.0 added the automatic recognition of charge session during offline periods.
I was just wondering if there would be a way to improve the resulting "added energy" calculation. As the charge states at beginning and end of the session (or before and after the offline period) are correctly saved, a more precise value of the added energy should be calculable.

I also noticed that "Charge Detail" Dashboard displays a different (also apparently false) value when no added energy is recorded for the charging session. Here the screenshots for the 2 first sessions:

Charge 1: no added energy recorded in Log nor in the charge_process

Charge 2: added energy recorded in data but is wrong
