My Blueprint can replace Alarmo completely, but you could also use it to just sync the Alarm states and/or use other features present.
There are some others available in the Blueprints Exchange that just sync the Alarm states when connected with Z2M. In Z2M the Keypad is just a ‘Device’ and not an Alarm Panel itself.
Both have been replaced by a combined version:
This blueprint provides a comprehensive, flexible alarm system solution that works natively with Home Assistant. No custom components required. Perfect for home security, office monitoring, or any security application, it delivers a responsive and user-friendly experience.
