Looks real good? How accurate is the Battery Capacity Chart my Powerwall2 is only 4 years old and the chart indicates only 73% warranted out of the 13.5 Kwh

Ahh, now it's having issues in the Tesla app also, so must be Tesla.
Shows 0% on the main page:
~50% in the details, which is accurate:

Yeah, these are usually just data issues, but the system is working as designed during these "hiccups". Eventually it returns to normal.
I’m a new owner, but this is what I have observed to date.
Hey all. both the Windows and Android version of Powerwall Companion are now showing a battery level of "NaN". This is because Tesla seems to have removed the total_pack_energy value from the API. Currently the app is using this to calculate the current percentage level, hence the error. I can easily update the app to pull the percentage charged from elsewhere (and will do so ASAP), however I suspect the battery status page will need to go assuming this is a deliberate change from Tesla. Basically it seems they do not want people to know what their current max storage level (and hence the degradation level) is...
I currently have a bun Fight with Tesla over the capacity of the powerwall 2 dropping to 73% after 3 years. maybe they are trying to hide this information due to Faulty batteries and this is their way to stop complaints.
I've pushed updates to both the Google and Microsoft stores to fix the battery percentage; the updated versions (6.3 on Windows, 1.43 on Android) should be available in the next 24 hours.
Battery degradation data will be unavailable unless they restore this data in the API. I'll investigate getting this data from the gateway like NetZero but this will take more time.

@tomho Just a thought here... The Peak/OffPeak separators are hard to see on the black background (in fact I didn't even know they were there until I zoomed in for this screenshot). Could we add an option make that bar solid colors (green/red/yellow) similar to the "Self Consumption" bar at the very bottom of the page?

Only on the same network. Tesla removed the nominal full pack energy from the cloud API, so there is no other option.
On the bright side, the gateway API shows stats for individual batteries, so when I get the Windows version updated there will be more info than there was before.
Ah - why didn't I think of that! Thank you, all back up and running. Great job, very grateful.
I've now updated the Windows app to pull data from the local gateway. The bad news is that you will only get fresh data when on the same network as the gateway, although it does cache the data so you'll still see something when you're disconnected. The good news is that users with multiple Powerwalls will be able to see the degradation level (including history) of each individual battery.
This was quite a big change which I've rushed out, so I've decided to roll it out slowly in case there are problems. So you probably won't get the release pushed to you just yet, but if want to try it out you can open the Microsoft Store, go to Library and click Get Updates manually, and it should update to 7.0.
If you see any issues, please let me know on this forum or by email (please don't leave a one star review!) and I'll try to fix it ASAP.
