Default characterisic value is generating errors in HA logs when unsupported

[MoFtZ]

BACKGROUND

My HA setup is using HomeKit Bridge to expose an Alarm to HomeKit.

The HA logs contain the following errors:

Logger: pyhap.characteristic
Source: components/homekit/type_security_systems.py:125
First occurred: 21:12:49 (1 occurrences)
Last logged: 21:12:49

SecuritySystemCurrentState: value=0 is an invalid value.

Logger: pyhap.characteristic
Source: components/homekit/type_security_systems.py:134
First occurred: 21:12:49 (1 occurrences)
Last logged: 21:12:49

SecuritySystemTargetState: value=0 is an invalid value.

When I enable debug logging, I get the following:

2024-08-23 21:12:49.123 DEBUG (MainThread) [homeassistant.components.homekit.accessories] Add "alarm_control_panel.alarm" as "SecuritySystem"

PROBLEM

The two errors in the HA logs refer to the following code: https://github.com/home-assistant/core/blob/611723e44bd22bbf43226897fc4632af42f69bf0/homeassistant/components/homekit/type_security_systems.py#L125 https://github.com/home-assistant/core/blob/611723e44bd22bbf43226897fc4632af42f69bf0/homeassistant/components/homekit/type_security_systems.py#L134

I believe the issue is that the default value for the characteristic (value 0) is not supported. The call to configure_char will eventually reach code that throws a ValueError exception, and that gets caught and handled. The exception handler will then return a sane value.

EXPECTED BEHAVIOUR

Exceptions that are handled and ignored should not be writing to the HA logs.
