Tesla Powerwall 3 integration not accepting password

Third party integrations

Hello, I just got a new Home Assistant Green today (07/03/2026) and have a Tesla Powerwall 3 installed since March 2026. I can easily access the Powerwall 3 metrics through the Tesla app and through the Netzero for Powerwall app, but I cannot log in via the Home Assistant integration. It gives me an invalid login error even when trying every password combo i see written on the device (including last 5 of SN and such).

Copied the error below, but sanitized the ip address:

Authentication failed with error: Access denied for resource
https://xxx.xxx.xx.xxx/api/login/Basic: bad credentials: Login Error

I'm on the latest version of HAOS on the HA Green hardware. My Tesla PW3 firmware is 26.18.1 fabf8f5a.

Side note: I couldn't easily see my Powerwall 3 IP address on my ASUS router, so I had to use the Netzero app (devices > Gateway) to even find the IP address.

Bump. Anyone know what’s going on? Is this integration dead?

I spoke to a Tesla representative.
The new powerwall 3 no longer has a gateway. The way he described her was the master is the controller and that’s it. All there is is Wi-Fi..

Has anyone been able to recently connect ha to the new powerwall 3 in 2025/2026?

Edit:
No more.
