Tesla Powerall Integration issue returning log error for Home Assistant WebSocket API integration

[bardolan]

The problem

The entity "Home Energy Gateway Off-grid operation", which normally functions as a switch for the off-gird operation mode has failed multiple times in the last day with the message "Failed to perform the action switch/turn_on. Setting off-grid operation to IslandMode.OFFGRID failed: Access denied for resource https://ip-redacted/api/v2/islanding/mode: Unable to POST to resource: User does not have adequate access rights"

The issue was first noticed the morning of 12/23/24, though it could have begun anytime after 10:10PM EST 12/21/24 as the associated automation does not run over weekends and therefore I only noticed the issue ysterday morning.

2024.12.5

What was the last working version of Home Assistant Core?

No response

What type of installation are you running?
