🛡️ Alarmo ↔ Bosch Smart Home Two-Way Sync Blueprint

Blueprints Exchange
1

Hi everyone,
I’m sharing a custom blueprint that creates full two-way synchronization between Alarmo and the Bosch Smart Home alarm system in Home Assistant.

This blueprint ensures that when you arm or disarm from either the Bosch system or Alarmo, the other one mirrors the state—including synchronized arming countdowns (exit delays) and final alarm modes.

:white_check_mark: Features

  • :repeat: Two-way sync between Alarmo and Bosch alarm panels
  • :stopwatch: Exit delay starts in sync on both systems
  • :brain: State-aware logic: avoids redundant commands or infinite loops
  • :white_check_mark: Syncs the following states:
    • disarmed
    • arming
    • armed_home
    • armed_away
    • armed_night

:brick: Requirements

  • Alarmo installed and configured in Home Assistant
  • Bosch Smart Home Controller with the extended integration:

:warning: The official Bosch SHC integration in Home Assistant does not include alarm support (no alarm_control_panel).
You must install the custom extended integration by @tschamm:

Please refer to their repository for setup and support related to Bosch SHC features.

:rocket: How to Use

  1. Make sure both Alarmo and the boschshc-hass integration are installed and working.
  2. Import the blueprint using the link below.
  3. Create a new automation from the blueprint and select:
  • Your Alarmo entity (e.g., alarm_control_panel.alarmo)
  • Your Bosch alarm panel (e.g., alarm_control_panel.intrusion_detection_system)
  1. Ensure both Alarmo and Bosch are using the same exit delay time.

I created this blueprint because I wanted Bosch and Alarmo to work seamlessly together within Home Assistant. Now both systems stay fully synchronized, whether you’re using the Bosch app, an automation, or the Alarmo interface. Hope this helps others with the same setup!
