Powerwall local API access denied on Powerwall firmware 20.49.0

Third party integrations

After my Powerwall had a firmware upgrade the integration with HA busted. I deleted the integration and tried to re-add it. I am seeing the following in the logs after I enter the IP address of the PW. I have logged in successfully to the PW using a browser. I notice that when using the browser to send the same URL (/site_info) to the powerwall there are a couple of cookies sent ‘AuthCookie’ and ‘UserRecord’.

I am running 2021.1.5

Just chiming in, recent firmware update also broke the integration for me. Still running 20.49.0.

Edit: API auth changes on the Tesla side. Looks like there is some activity on this thread to get it working as a custom component, otherwise you’ll have to wait for someone to jump in and fix the official Powerwall integration: Add support for Tesla Powerwall

Same for me!

Looks like I’m doing a “me too” on this one. Does anyone know how to officially ask the devs to fix this?

Looks like it has been fixed already :blush:
GitHub - bdraco/powerwall: Updated powerwall integration for HASS

From my computer I can log into the powerwall then after that I can access it again with http://192.168.1.6/api/system_status/soe and that gives me the percent charged.
still wasn’t working from home assistant, so created an iframe card (webpage) and got to the powerwall that way, but when I click on login, it displays the turn powerwall on and off message quickly but does not stay on that page…
