Powerwall Companion - updated Windows app

[fossilraf]

Easiest way is go to Microsoft store then click on library icon in lower left then update all. simple

... The main numbers on the page remain as they are too minimise clutter.

...

Well, known or unknown, I didn't know, when you hover cursor over those numbers you get the actual usage data, kWh, to two decimal place.
Great.

Hi, thanks for creating this. Is it possible to add the PW capacity info to the Android app? Thanks.

It's already there... Settings > Extra Info > Powerwall Stats

Got it, thanks!

Hey all, got another update almost ready to go. I'm moving to Tesla's new "Fleet API" which gives you more control over which apps get access to which data (and will likely be the only supported way to call Tesla's API soon). This is a fairly big change so I want to make sure I don't break anything - if anyone is willing to test this and let me know if it's working for you, could you please DM me your Microsoft Account email address?

I just had my system installed. 2 Powerwall 3s, already says -7% degradation.

Negative degradation means your storage is higher than the warranted amount.

Thanks for the clarification! I did read them backwards

Hi @tomho

I've been using the Powerwall Companion app for a while now, but the latest update seems to have screwed things up for me. I've done the login, and allowed both permissions, but I get this error:

Any ideas what I've done wrong, or how to fix?

Thanks for letting me know. I'm updating the app to work with the new Fleet API.. Possibly it's not working for users in all regions... I'll look into this tomorrow.

 

[Grayson73]

I had that earlier but it has been working since.

 

[tomho]

@miles_per_kWh I made some updates to the app registration - can you please try again and let me know if it works?
Also please let me know what version you have installed (visible in the Settings page).

 

[tomho]

Also, I've published an update to the Android app in the beta stream that uses the Fleet API. I'd love some testers for this too (particularly if you're from Europe) before I push this out to all users. You can join the beta at Powerwall Companion - Apps on Google Play (scroll down until you see "Join the beta").

I've clicked to open the app today, and it's worked straight away, no need to log out/in first.
I'm using 4.9.1.0

When I exported a day's data, the totals didn't add up to the summary in the app. Am I doing something wrong? Is there a way to export a total for each day, such as 34.0 kWh grid usage, 9.3 kWh solar?

Hi tomho,
Love the App and was just curious, do you have plans to add the ability to calculate income and expenditure for those of us that export power ?

When you are on the daily view, the exported data contains instantaneous power values (in watts) at 5 minute intervals. If you add all the numbers together and divide by 12 (because there are 12 five minute periods in an hour) you'll get the approximate total energy for the day in Wh. However this will only be approximate as the power usage may change between the readings. To get an accurate total I'd suggest switching to weekly or monthly view and exporting from there, as that will give you the daily energy totals without any need for manual calculations.

I hadn't considered that. Can't you get your solar feed-in income from your power company?
A lot of people who want to do more complex analysis of their usage use the data export feature and then do the calculations in Excel or similar.

Since you are reading off of Tesla's data, are you only using their 5-minute number? Does Tesla integrate accurately what happens between the 5 minute data?
Are you able to integrate the raw reading gathered x number of times in that 5 minute interval?
