+It is highly recommended to set `endpoints[].alerts[].send-on-resolved` to `true` for alerts
+of type `ilert`, because unlike other alerts, the operation resulting from setting said
+parameter to `true` will not create another alert but mark the alert as resolved on
+ilert instead.
+
+Behavior:
+- By default, `alerting.ilert.integration-key` is used as the integration key
+- If the endpoint being evaluated belongs to a group (`endpoints[].group`) matching the value of `alerting.ilert.overrides[].group`, the provider will use that override's integration key instead of `alerting.ilert.integration-key`'s

+#### Configuring HomeAssistant alerts
+To configure HomeAssistant alerts, you'll need to add the following to your configuration file:
+
+```yaml
+alerting:
+  homeassistant:
+    url: "http://homeassistant:8123"  # URL of your HomeAssistant instance
+    token: "YOUR_LONG_LIVED_ACCESS_TOKEN"  # Long-lived access token from HomeAssistant
+
+endpoints:
+  - name: my-service
+    url: "https://my-service.com"
+    interval: 5m
+    conditions:
+      - "[STATUS] == 200"
+    alerts:
+      - type: homeassistant
+        enabled: true
+        send-on-resolved: true
+        description: "My service health check"
+        failure-threshold: 3
+        success-threshold: 2
+```
+
+The alerts will be sent as events to HomeAssistant with the event type `gatus_alert`. The event data includes:
+- `status`: "triggered" or "resolved"
+- `endpoint`: The name of the monitored endpoint
+- `description`: The alert description if provided
+- `conditions`: List of conditions and their results
+- `failure_count`: Number of consecutive failures (when triggered)
+- `success_count`: Number of consecutive successes (when resolved)
+
+You can use these events in HomeAssistant automations to:
+- Send notifications
+- Control devices
+- Trigger scenes
+- Log to history
+- And more
+
+Example HomeAssistant automation:
+```yaml
+automation:
+  - alias: "Gatus Alert Handler"
+    trigger:
+      platform: event
+      event_type: gatus_alert
+    action:
+      - service: notify.notify
+        data_template:
+          title: "Gatus Alert: {{ trigger.event.data.endpoint }}"
+          message: >
+            Status: {{ trigger.event.data.status }}
+            {% if trigger.event.data.description %}
+            Description: {{ trigger.event.data.description }}
+            {% endif %}
+            {% for condition in trigger.event.data.conditions %}
+            {{ '✅' if condition.success else '❌' }} {{ condition.condition }}
+            {% endfor %}
+```
+
+To get your HomeAssistant long-lived access token:
+1. Open HomeAssistant
+2. Click on your profile name (bottom left)
+3. Scroll down to "Long-Lived Access Tokens"
+4. Click "Create Token"
+5. Give it a name (e.g., "Gatus")
+6. Copy the token - you'll only see it once!
