Set default code in frontend for alarm_control_panel

[gjohansson-ST]

Story

Similar to the implementation of a default code for locks we should do same for alarm_control_panel.

Proposal

• Implement a user customization for alarm_control_panel so that a user can set a default code for a certain alarm_control_panel entity in frontend.
• Implement validation similar to lock entity but also consider attr_code_arm_required.

Usage

• Service calls are updated so if default code is set, code in service calls are optional as it will use default code if no code is supplied (if validation requires a code)
• Frontend is updated (alarm_control_panel card) so if default code is set, it's possible to click arm/disarm without supplying a code if required as it will then use the default code.

Other

• Integrations currently setting a default code as part of config entry options can now remove this.

Result

Users can now directly in frontend for the specific alarm_control_panel entity provide a default code which will be considered in validation and thereby code can be omited in service calls /frontend even if code_format has been set to validate the code.

And it broke my alarm panel interpretation and I have no work around as my integration has no unique ID… Why are you forcing people to use an alarm code? Who breaks in your house and sets the alarm? Who breaks in, and figures out your HA integration quick enough to disarm your alarm? Most crooks will flee at the sound of an alarm… What technology advanced dystopia do you live in? The default was fine. Either make your case the edge case or implement a workaround so everyone else can proceed as usual. At least add the “code_required” Boolean to configuration so I can go back to living my life!

You might want to reconsider your tone just a little bit... Everyone tries to improve things here, and no one has the intention to break things. Above all, we are all humans here too.
