Do Not Upgrade HA Too Frequently [Updated May 15, 2021]

I strongly do not recommend upgrading to core-2021.3.1 and later, including core-2021.5.3 From core-2021.3.1 onward there are some strange bugs. The version that is currently stable for the author is still core-2021.2.3

Problem Description

After the author upgraded Home Assistant to the latest version, HAVCS could no longer start normally.

Home Assistant version that can run HAVCS normally: core-2021.2.3 Home Assistant version that cannot run HAVCS: core-2021.5.3

Checking the Home Assistant logs showed this error:

AttributeError: 'ApiConfig' object has no attribute 'base_url'

The full error message is:

Logger: homeassistant.config_entries
Source: custom_components/havcs/__init__.py:250
Integration: Home Assistant Voice Control Skill (documentation)
First occurred: 18:05:49 (1 occurrences)

AttributeError: 'ApiConfig' object has no attribute 'base_url'

Issue Investigation

After checking the related资料 and docs, I found that Home Assistant has already deprecated config.api.base_url. It should be replaced with the new helpers.network.get_url.

Fix

Use File Editor to open /config/custom_components/havcs/__init__.py, replace every config.api.base_url with helpers.network.get_url, then restart Home Assistant.
