+## Use cases
+
+This integration enables several use cases to optimise efficiency of a solar and/or battery storage system.
+
+### Solar charging
+Use the charger mode to maximize solar consumption:
+- Set the charger to "Paused" when solar production is low
+- Switch to "Max charge" during peak solar hours
+
+### Battery storage
+If you have a home battery system:
+- Charge your EV when the battery is above certain capacity
+- Pause EV charging when the battery needs replenishing
+
+## Examples
+
+### Send a notification on status change
+
+To be notified when the status of the charger changes, for example when a vehicle is plugged in, you can use an automation.
+
+{% raw %}
+```yaml
+# Example automation
+triggers:
+  - trigger: state
+    entity_id:
+      - sensor.ohme_home_pro_status
+    from: unplugged
+actions:
+  - action: notify.mobile_app_iphone
+    data:
+      message: "Vehicle plugged in"
+```
+{% endraw %}
+
+
+## Troubleshooting
+
+### Entities are shown as unavailable
+You may need to power cycle your charger. Please see the [manufactuer's guidance](https://ohme-ev.com/support/my-charger-is-offline/) for the procedure.
+
+## Data updates
