+
+The **Olarm** {% term integration %} connects Home Assistant with Olarm's range of smart alarm communicators. It allows you to monitor, control, and automate your alarm system directly from Home Assistant—enhancing security through smart home automation.
+
+Olarm upgrades traditional alarm panels with remote access, real-time notifications, and seamless smart home integration.

+
+## Supported devices
+
+The following devices are known to be supported by the {% term integration %}:
+
+- Olarm GEN1 – Paradox
+- Olarm GEN1 – Universal
+- Olarm PRO
+- Olarm PRO 4G  
+- Olarm MAX
+
+## Prerequisites
+
+- An active Olarm account
+- A compatible Olarm {% term device %} connected to a supported alarm panel
+- An active subscription for the device
+- The device has public API access enabled
+
+## Before Configuration
+
+Before adding the integration to Home Assistant:
+
+1. In the Olarm App: Go to **Profile** > **Device List** > **[Select Device]** > **Developer Settings**, then enable **API Access**
+2. Ensure your Olarm device is online and has an active subscription
+
+{% include integrations/config_flow.md %}
+
+## Entities
+
+The **Olarm** {% term integration %} provides the following {% term entities %}.
+
+### Binary sensors
+
+The integration creates various binary sensors depending on your alarm system configuration:
+
+#### Zone sensors
+
+- `binary_sensor.zone_XXX_<zone_name>`: Individual zone status for each configured zone
+  - Device class automatically set based on zone type (door, window, motion)
+  - Extra attribute: `bypassed` indicates if the zone is currently bypassed
+
+#### Zone bypass sensors (optional)
+
+- `binary_sensor.zone_XXX_bypass_<zone_name>`: Shows bypass status for each zone (only if bypass {% term entities %} are enabled during setup)
+
+#### System sensors
+
+- `binary_sensor.ac_power`: Indicates if AC power is available to the alarm panel
+
+#### LINK module sensors (if LINK modules are connected)
+
+- `binary_sensor.<link_name>_link_input_XX_<input_name>`: LINK input status
+- `binary_sensor.<link_name>_link_output_XX_<output_name>`: LINK output status (for outputs in latch mode)
+- `binary_sensor.<link_name>_link_relay_XX_<relay_name>`: LINK relay status (for relays in latch mode)
+
+#### MAX module sensors (if have an Olarm MAX)
+
+- `binary_sensor.max_input_XX_<input_name>`: MAX input status
+- `binary_sensor.max_output_XX_<output_name>`: MAX output status (for outputs in latch mode)
+
+## Examples
+
+### Automation examples
+
+#### Zone monitoring
+
+```yaml
+alias: "Front Door Opened"
+trigger:
+  - platform: state
+    entity_id: binary_sensor.zone_001_front_door
+    to: "on"
+action:
+  - service: notify.mobile_app
+    data:
+      message: "Front door has been opened"
+```
+
+## Troubleshooting
+
+### Common issues
+
+- **No updates or control issues**: Ensure the {% term device %} is online and the subscription is active
+- **Missing {% term entities %}**: Reload the {% term integration %} or restart Home Assistant
+- **Login issues**: Double-check your Olarm account credentials and ensure API access is enabled in the Olarm app
+- **LINK entities missing**: Ensure the modules are properly connected and configured in the Olarm system
+
+### Removal
+
+{% my integrations badge %}
+
+1. Go to **{% my integrations icon title="Settings > Devices & Services" %}**
+2. Locate the **Olarm** integration
+3. Select the integration, then select **Delete**
+
+## Known limitations
+
+- A maximum of 5 Olarm {% term device %}s per {% term integration %} instance are currently supported
+- Only one Olarm user account per Home Assistant instance - multiple Home Assistant instances require different Olarm user accounts
+- Zone bypass {% term entities %} are optional and must be enabled during setup
+- LINK binary sensors {% term entities %} only available if the respective modules are connected to your system
+- MAX binary sensors only available if you have an Olarm MAX
+
+## Use cases
+
+- Get real-time alerts for alarm events and zone activity  
+- Monitor alarm system health
+- Integrate LINK modules for expanded I/O capabilities
