Slightly cryptic title I'm sure, but I am looking to see what others have gathered on the current state of their Powerwalls "
total_pack_energy" from the Tesla API. Details about accessing the API can be found here: State And Settings and the total_pack_energy stat comes from the data obtained via the API link: https://owner-api.teslamotors.com/api/1/powerwalls/:battery_id/status (once one has attained an oAuth token, see api website for details if needed).
I've been collecting data from my Powerwalls since June and I've been noticing that the total stored energy of my pack has been decreasing a lot over time. I would assume this would happen with any batteries but I had my Powerwalls install in February of this year and since then I have lost about 13% of my total pack energy which seems like a lot for less than 1 year of use and also considering the cars don't seem to loose that much total power in the same time frame.
In any regards, I wanted to create a post where we can collect such data and share it with others to help gauge if our Powerwalls are loosing more or less energy storage over others. See the data below and post yours if you can:
