New in v8.2, now on slow rollout to the Store (you can check for updates manually to force update): Building on the rate plan features in the last release, Powerwall Companion is now able to estimate your energy costs, using a combination of the Powerwall's reported energy usage at different...

Thanks for the suggestion. I'll look at some improvements to data export in the coming weeks.

No it's up to me. Broadly, I bump the first number when new features are added. Second number for non trivial improvements. Third number for targeted bug fixes. 8.0.0 has the new energy tariff display; 8.0.1 fixed some bugs.

@gmtom1 Figured out what was wrong. Turns out WebView2 (integrated web browser component) isn't supported on 32 bit ARM, which is all I was building for. Version 8.0.1 has been rebuilt for ARM64 so hopefully you'll have more luck with this one (although unfortunately I still can't test it).

Version 8.0.0 is now available in limited release but you can force an update in the Store. There's a new option in Settings to show your current electricity price at the bottom left. This should work if you have set a custom energy rate plan in the Tesla app. If you are in an area where you can...

Sorry it's still not working. I did make some changes to try to fix this, but I have no ARM device myself so can't reproduce the issue. I'll research this more and see what I can do.

Version 7.4.1 is in the store, you can force an update by opening the store app. The main change is to restore the exported energy data to the format it was before Tesla's recent changes. @RKCRLR and @gmtom1 could you please try upgrading and let me know if this fixes the issues you raised too?

Thanks, this shouldn't be happening. Will try to fix for the next release.

Can you share a screenshot? It should be showing data.

Thanks for the report, I haven't heard about this before. I'll need to look into it. I suspect the fact that you are on ARM is relevant.

@GlennAlan more on your last question: I found a day when my battery went from 0 to 100 without any recharge beyond that. It is showing a daily total of 14.04kWh charged in the battery, while the degradation page shows ~12.7kWh capacity. The difference is not enormous but it's not close enough...

Hey Glenn, thanks for using the app, glad you like it! Thanks, it seems there are some variations in how to connect depending on the age of the Powerwall. Mine doesn't have a dedicated password on the label, but the new ones seem to. I'll update the instructions to try to eliminate the...

Correct, the app works fine if you don't click on the Chart page. The good news is I've found some evening time to rush out a fix; should be available within a few hours.

Can you elaborate?

So I found out why the app is slow. Tesla has changed their calendar_history API (once again, without notice). Previously when requesting energy stats, it would show a single result for each day (for daily/weekly/monthly periods) or month (for yearly periods). Now it is showing values for every...
