Thank you for helping!

Seems the problem may be related to trying to get a new token on every set_operation. Instead, we need to keep the token around and refresh it after it expires.
That is a bit more complicated to achieve so I will need some time to code it. In the mean time, I modified it to keep the token after the first login. So, in summary, not much better than having the token generated and hard-coding it…
If it complains, add a “access_token” entry in the “tesla_gateway” configuration (empty string as a value).

Thanks. I’ll try that.

My PW’s got updated to 20.49.0. Now the local web view requires login and the Powerwall integration only shows Unavailable. The release notes for 20.49.0 states "increased security for TEG 1 and 2).

estebanp · February 9, 2021, 5:37am

Same here, I will take a look to the local web. I logged in again after the update but the usual http request is failing.
I also did another update to convert the SSO token to an “Owner” token and to call refresh. Seems to be working, multiple calls succeed. Will run it for a day or two before posting it (if someone is willing to test it I can also post it, just want to reduce the amount of noise).

nathanielh · February 9, 2021, 5:39am

A post in https://github.com/home-assistant/core/issues/45955 may have some useful info, specifically a post by bdraco https://github.com/bdraco/powerwall.

estebanp · February 9, 2021, 6:08am

yes, it will get more tricky because the login process is with another url, so we may not be able to use the template sensor anymore…was trying to use another sensor to get the login token and then pass that as a state, but the rest sensor doesnt allow templates on headers

Matthew_King · February 9, 2021, 7:14am

Oh I legit thought I had broken something as this stopped working same time I updated my blinds, glad to see it’s not just me. I did reset the login on my powerwall but yeah the integration just fails at unexpected error.

estebanp · February 9, 2021, 7:28am

The fix @nathanielh posted was not released yet. However, if you download that powerwall integration and place it on custom_components, you override the HA one. After resetting my PW passwords, I was able to connect (customer password) and I see the data now.

Matthew_King · February 9, 2021, 7:52am

Thanks man I downloaded that repo and put it in my custom components, but when I try to run it I get this error

 [homeassistant.config_entries] Error occurred loading configuration flow for integration powerwall: No module named 'homeassistant.components.dhcp'

estebanp · February 9, 2021, 7:58am

That may be related to some other component this one uses, seems like you need to enable this: https://www.home-assistant.io/integrations/dhcp/

jimmyleet · February 9, 2021, 10:48pm

Yep was the problem I updated my hass and now I get further but when I go to the integration I get this screen

This is the error in the log

UPDATE:

Managed to fix the problem turns out the top box is ip address not the email login so all working now.

Orikson · February 10, 2021, 7:43pm

Hello everybody. I’m new to HO, so sorry if I have some stupid questions

I also added my Powerwall 2 into HO a few days ago. It also worked nearly 24 hours and I recorded data from 2021-02-07 20:38 until 2021-02-08 19:28. After that, no new data was recorded. Trying to play around with the integration did not help so I tried to remove and again add it. When I try to add it again, I get only the error “Unknown Error” after entering the IP address.

grafik

In addition, after trying to add the Tesla Powerwall integration, I get the following error in the log

I would like to test the reworked code from your post by putting it into the init.py. But I cannot find the folder /usr/local/lib/python3.8/concurrent/futures/ nor usr/src/homeassistant/homeassistant/components/powerwall/. Maybe because I removed the integration before?

How could I get this working so I could test this on my site as well?

estebanp · February 11, 2021, 4:37am

You need to download the component from https://github.com/bdraco/powerwall and place it in the custom_components folder, then restart HA
The component that is in the official HA release still doesnt have the fix

Orikson · February 11, 2021, 7:35pm

Thank you very much for your work It worked for me right now, at least I’m getting values again. Also I did not see any strange errors in the logs, so it seem to be fine for now.

Hodor · February 12, 2021, 9:03am

So Im now completely lost.

I implemented the fix from bruceH5200 and this worked fine. Now today Ive lost access to the local sensors. I have tried to follow the thread from the last few days but Im really struggling to follow what has changed.

interestingly I have two IP addresses for my powerwall gateway, both are fixed. I used to access the local API using one ip address, which I assume is the one I set up the integration on initially months ago. However if I now use the other IP address I can access the API just fine via a browser.
I have tried finiding where this IP address is stored in the integration, but no luck.

I have also downloaded and installed the github custom component listed above and restarted HA, but still no luck.

Can anyone advise what needs to be done after the token fix posted by Bruce a couple of weeks ago to get this back working again?

Many thanks for any help.

BruceH5200 · February 12, 2021, 9:29am

The script doesn’t access the powerwall locally, it is talking to the Tesla servers via the API who in turn talk to the powerwall. So the IP address of the powerwall is not relevant.
The script still seems to be working for me with the hardcoded key.

Hodor · February 12, 2021, 9:34am

I got the same error: ```
[homeassistant.config_entries] Error occurred loading configuration flow for integration powerwall: No module named ‘homeassistant.components.dhcp’


I added "dhcp:" to the config.yaml but then get an error "Component error: dhcp - Integration 'dhcp' not found."

I have default_config: in the config.yaml.

No idea how to get the powerwall component from bdraco working.

Hodor · February 12, 2021, 9:48am

The changing mode from backup to self powered is still working using your fix, which works great.

However the sensors I had set up using the local gateway API have all stopped. I was pulling these from the API using local IP address (https://192.168.X.X/api/meters/aggregates) but as of this morning they have all dissappeared. Navigating to that address now fails.

If I change the IP address to another that is associated with the gateway, this works…

Ah - hang on. I wonder… I was working in the cabinet last night, I wonder if Ive gone and broken/loosened the network cable that is connected to the gateway and Im now polling by wifi…

This could be a big egg on face moment…

BruceH5200 · February 12, 2021, 10:02am

Has the firmware on your powerwall upgraded, I think may have been making security changes.

Hodor · February 12, 2021, 10:13am

They must have been doing something, firmware hasnt updated, but a restart of the gateway has forced it to reconnect to the local network. Cable was fine, but gateway had lost its local IP address for some reason. Sensors all back up and running again now.

Still doesnt explain why the custom component is failing saying dhcp is not available when i have default config enabled. Seems I may have somethingunderlying wrong with my HA setup.
