Tesla Powerall integration fails to load when one Power Wall is failing

[matellis]

The problem

I have four powerwalls connceted to one gateway. One of the powerwalls is failing, in the Tesla One app it says "Unable to Read Data" for that unit. Consequently the Tesla Powerwall integration fails to load at start and when instructed to reload. Error message in logs says "ValueError: '' is not a valid GridState'. See logs for specific error stack.

It would be great if the integration could handle this and still load, and even better if it could flag that there may be a fault. Tesla didn't tell me until I investigated and found this.

What version of Home Assistant Core has the issue?

core-2024.2.1

What was the last working version of Home Assistant Core?

Anything in the logs that might be useful for us?

"ValueError: '' is not a valid GridState'" The faulty powerwall is returning no data.

I have this same issue, and to my knowledge none of my powerwalls are failing yet.

Upon further investigation with the NetZero app, it would indeed appear one of my Powerwalls is down/failing.

@matellis aside: how did you set up the Tesla One app? It asks me to connect to the wifi but I worry about having to reconfigure the entire thing if I 'add it as a job'

[matellis]

I did "Begin Install" and then scanned the QR code. Or you can ping support and tell them you've got a faulty power wall.

Got it, thanks - that worked; was nervous about it reinstalling. Definitely one down. :(

[nugget]

Having the same issue here. I have three Gateways configured and one of them breaks any time I try to upgrade to 2024.2. Restoring back to Home Assistant 2024.1 "fixes the glitch." I've tried with 2024.2.0 and 2024.2.2 both with the same problem.

Curiously, the Tesla custom integration installed via HACS is still able to communicate to all three Gateways, but I thing that's going through the cloud API and not direct to the gateway locally.

No sign of trouble in the Tesla app, but I installed the NetZero app and I can see that the failing Powerwall lacks a graph for "Powerwall" although "Solar", "Home", and "Grid" all look fine. So it does appear there's a config or provisioning issue with the Powerwall that's failing in 2024.2.

@borski @matellis what are you seeing that you're describing as a "down" Powerwall? My failing powerwall seems to be functioning perfectly well otherwise, aside from this glitch.

[borski]

Using "Diagnostics" in the NetZero app I can see one powerwall is not responding. My installer came and checked it out with Tesla on the phone and they RMA'd it. New one is getting installed today.

[nugget]

Thanks, very helpful. They sure didn't make the diagnostics option easy to find in the NetZero app.

All my Powerwall batteries are healthy on the failing gateway, but I do see that I have an orphan inverter showing up in the Tesla app under a 4th "house" and I bet that's the source of my brokenness that's causing problems in the integration. One of my 4 batteries is disabled due to the inverter misconfiguration (or some other issue, probably related). See the issue I opened below on the library repo for more details

[nugget]

I just tested and confirmed that the underlying bug in the library is fixed in tesla_powerwall v0.5.2. As soon as Home Assistant is updated to use that version we should be good to go. Thanks @bdraco !

[deveus]

I think thread might have just helped me discover that one of my powerwall batteries isn't working. I was chasing down the same error message, found this issue report, and it led me to troubleshooting the actual hardware. Ty @borski for sharing the name of the NetZero app and pointing me in a new direction. Will report back

[deveus]

Confirmed. Tesla is gonna RMA my powerwall battery because they say it's been broken for months. Tesla app reports nothing wrong and no error messages, but Home-Assistant spotted it and threw an error in the logs. Ty friends. Should be replaced soon.

Edit May 10: Bad Powerwall replaced. Integration immediately started working

[jrester]

@matellis @nugget Could you please try the new home-assistant version 2024.6.2, and check if the problem is fixed?

[nugget]

I've since had my installation repaired and I no longer have an inoperative battery to test the bug with.

[matellis]

It's not good that we have to discover ourselves when our very expensive Powerwalls are failing. I wonder how many folks are running sub-optimal after paying thousands and don't know it? Glad you're both mended/on the mend.

[matellis]

@jrester I'm also fixed after my unit got replaced, so unfortunately I'm unable to help, just like @nugget Maybe we should keep this ticket open to see if anyone complains this is for them and close it in a few weeks? Thanks for the patch. Somehow I'm sure I'll be back with more problems in the near future.
