powerwall2 VS pypowerwall

FWIW the API (https://github.com/vloschiavo/powerwall2) reports a state of energy greater than 0 (5% I think) when the app shows you 0%. i.e. there’s a lower buffer. I understand the anxiety seeing them at 0% though.

umm, there is... https://github.com/vloschiavo/powerwall2

You can see individual powerwall stats using the local gateway API: https://github.com/vloschiavo/powerwall2

See here for documentation: https://github.com/vloschiavo/powerwall2 Additionally, Home Assistant has out-of-the-box integration using this API. Note that you must have a backup gateway/powerwall for this to work.

If you know how to use Python, you can run the following script to record the vitals and see what is going on. You have to install pypowerwall at: https://github.com/jasonacox/pypowerwall

You can get pretty detailed current data through the gateway's web API. Here's a python module I use on mine: https://github.com/jasonacox/pypowerwall

Finally, if you are tech hacker/maker, you will love the rich APIs that you get with the Powerwalls. There are so many fun projects like pyPowerwall to gather data or control your Powerwalls. I spend way to much time on this. :) Check out Powerwall-Dashboard for example.

It sounds like the firmware update failed trying to upgrade the Powerwall itself (the TEPOD or TETHC device). I would run pypowerwall against your GW to see what additional data/alerts/errors you could find (using python) - something like:

That's awesome! I had to run the wizard to remove the Neurio and recall it had the settings still in there. Some of the site info forms did have me question things a bit so I suggest you screen capture the portal data, especially grid_code, just in case. If you have pypowerwall running, you can grab some of this as well:

What do you see when you log in to the Powerwall Gateway portal (local network or Gateway WiFi)? Or alternatively, use pypowerwall and run pw.poll("/api/troubleshooting/problems") and pw.alerts()

The Power Flow diagram is made possible by the pypowerwall proxy container and using a text/html Grafana panel and iFrame to render the animation. It is basically rendering the same thing you would see if you log in to the Powerwall Gateway.

I wish the Tesla app had more troubleshooting info. You might want to check out Powerwall-Dashboard or use pypowerwall and a Python script to get more info and the alerts that the PW+ is raising (requires pip install pypowerwall and you can use python -m pypowerwall scan to find your IP address):

Does https://github.com/jasonacox/pypowerwall make any sense to you? If so, you can use this library to get logs and additional data from your gateway that might help explain things.
