@JakobLichterfeld - ok, should be ready for testing!

[JakobLichterfeld]

Thanks so much!

@JakobLichterfeld - will add a small follow up PR - need to increase generate series to correctly calculate the average for the first 15 days...

no worries, love the eagle eyes.

@swiffer , How do you plan to use this moving average?

[swiffer]

I don't know. First interesting to see how charge level / battery usage changes over time and how much capacity is used usually... would be great to compare curves with other users and ensure percentiles always stay within the green lines. No deep knowledge about recommended charge levels here, sorry.

I don't understand the changes made to the charge level. It no longer displays the actual charge level of my car. How is this better? What am I suppose to glean from this data? Is there any documentation explaining the changes to charge level? Thanks.

Hi @jim0266 - you are not seeing the yellow line anymore?

we are making use of date_bin for charge level which is available from PostgreSQL 14 onwards - what version are you using?

[jim0266]

I'm missing battery level and usable battery level.

Hopefully this screenshot helps. From 9/4 to 9/14 we took at 3,300 mile trip. We charged as high as 90% on 9/5 and went as low as 16% later in the trip. None of that is captured in my data or I don't know how to configure it now to show that.

How can I see this accurate data? I'm not sure what use the current data is to me. What is it trying to tell me?

I'm also showing a DB error is this is part of the problem.

Thanks for any help or insights.

you need to upgrade your postgres instance - see here for instructions - and ensure you have a backup!

All was good until this last step:

For the version I used 17.1, which is the latest stable version of Postgres. I am hosted at Vultr.

image: postgres:17.1

Thanks!

can you compare the docker compose file with the one mentioned in the docs or post it here (redacted (passwords)).

[JakobLichterfeld]

Please open a separate Ticket, explain what you have done, post your docker-compose.yml (without secrets)
