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...

Yeah the Charts page is super slow. I haven't changed any code here and even old versions are affected, so something must have changed on Tesla's side. Still I'm sure I'll figure it out...

Hmm, I haven't made any changes that should have changed performance, but I'll look into it.

Looks like this can show after a firmware upgrade to PW2. According to you can choose not to upgrade and it should keep working (at least through the web interface). Can you please try this and then let me know if PWC works?

This didn't exist when I built the charts, but I'll look into it.

Is that a PW3?

Ah it's on the leaf, not the number. I'll put it on both.

Yep! There are tooltips on just about every element in the UI that should explain things.

No that won't help. The old version pulled the battery health from Tesla's cloud API, but I updated the app only because Tesla removed this from the API. The gateway is now the only source from this info.

Thanks Rob. Making the warranty line location-specific is on my to do list! I believe the warranty stipulates 80% after 10 years in a handful of European countries (Austria, Belgium, France, Germany, Ireland, Luxembourg, Netherlands, Switzerland, UK) and is 70% everywhere else.

Powerwall 3 will not work with the battery degradation unfortunately. The gateway API cannot be accessed in the same way.

The Tesla app pulls data from an undocumented API, while PWC uses the documented one. For some (not all) people the values can vary. I don't know why, nor do I know which is more accurate. But both are what's reported by Tesla.

No there is only one IP for the gateway. Going through the router is just the easiest way to find it.

Yes the 192.168.x.x is the LAN IP address, and the line under that is the MAC address. Only the IP is needed to connect, but the router shows the MAC addresses of all connected devices.

I disagree, this is almost certainly the gateway IP. If it were a PW2 the default password would be the last 5 digits of your serial number. But I think they said before they had a PW3, in which case this won't work.

7.1.2 should be in the Store now if you check for updates manually (under Library).

Great to hear! The new version will work with private networks too; there was a setting I needed to enable to make this work. So you'll be able to set your network up how you want (although FWIW the "Public" option is more secure).

I think I figured it out! Fix is coming in v7.1.2 which will be rolling out later today. But if anyone testing would like a workaround (which explains why some people could get this working previously) you can change the network properties for your current connection to "Public network".

Thanks for testing. If you're seeing NaN and no gateway settings, you do not have the latest version installed - please update in Google Play. I really want to get this working for everyone, so all testing/information/suggestions are helpful.

See the screenshot above. You need to select Powerwall Battery Health in the Extra Info section.

Choose Powerwall Battery health in the Extra Info section. I'm wondering if you can get the battery stats from your gateway with the mobile app.

Thanks, and sorry it isn't working for you. I think everyone gets the SSL warning in the browser and I do have code to explicitly ignore those errors. For my sanity, would you mind sharing a screenshot of your PWC Settings page?

I have never seen a Powerwall 3, but to get the IP I imagine the first step is the same for other Powerwalls, which is to log on to your Wifi router, browse the list of connected devices and look for one with a likely name. Quite possibly the name would have changed from the Powerwall 2 and it...

@h2ofun are you able to test the gateway stats in the Android version of the app? That has near identical code, so whether it does or doesn't work, it may help narrow down the issue. I would also love feedback from others on whether the gateway connection is working in Windows. It does work...

Thanks, that's a very generic error (same as what you get if you enter the wrong address), but given you've confirmed the address is correct this gives me something to go on (maybe SSL certificate issues?). Will look when I finish my actual job for the day. Thanks for your patience!

Do you have 7.1 yet? That will let you see the underlying error.

v7.1 will let you see more information when the connection fails.

Not unless you do some tricky (and frankly not recommended) configuration on your home router to publish your gateway to the internet. The Powerwall gateway is only accessible from the network in which it is deployed. I know it can be nice to view data from a remote location, but with Tesla...

No it should just be the raw IP. I might need to add some more diagnostics to the app to help figure out what's going on.

Thanks for testing. Did you just put the raw IP in to the settings page, i.e. without the https:// ?

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...

Sounds like you don't have the latest version. Check for updates in Google Play.

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.

We're back baby...

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...

I raised a question to Tesla about this in Energy endpoints no longer returning total_pack_energy and energy_left · Issue #215 · teslamotors/vehicle-command, let's see if they respond.
