Home Assistant - Custom Card \"#\" button The native Alarm Control Panel card does not include a # key for Force Arm, so you need to create a separate custom button card that can simulate the # key.

To install HACS. follow the following instructions
Installing HACS version 2 (Home Assistant Community Store)
Click on this link https://tsh.li/HACSLink


Press START



The Custom Button Card has been added via HACS
The procedure below creates a custom button for the # (or Force Arm key). However, it will not appear automatically in the Overview Dashboard. You either have to Take Control of the Overview page, or Create a new Dashboard where you can add items manually. I prefer to add a dashboard and leave the default Overview dashboard alone.
Assuming you have created a new Dashboard (default type), eg named \"HOME\". Take Control of it so you can manually configure. click in the pencil (EDIT) icon on the top right of the new dashboard, then click on Add Card button on the bottom right.
Which card would you like to add? - Choose Custom-Button from the list of available button types.


Configure the Button Card manually

enter the text below;
type: custom:button-card
name: \'Comfort # Key\'
icon: mdi:pound
color: rgb(28, 128, 199)
size: 10%
tap_action:
action: call-service
service: alarm_control_panel.alarm_arm_custom_bypass
data:
entity_id: alarm_control_panel.comfort_alarm

Press Save
The Custom button appears in the last spot. Change the position by pressing + or â button so it is below the regular keypad in the grid. It looks ok on PC but in different place in mobile app

The # key will force arm the security system when zones are open while arming.
Verify Installation. Restart Home Assistant to apply the changes.Check if the Button Card is now available in your Lovelace dashboard.
