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.
