+# Global Caché iTach IP2IR
+
+The Global Caché iTach IP2IR integration allows Home Assistant to control infrared devices through a Global Caché iTach IP2IR network infrared controller.
+
+The integration exposes infrared-capable ports as Home Assistant `infrared` entities.
+
+## Supported devices
+
+- Global Caché iTach IP2IR
+
+## Features
+
+- Automatic device discovery using:
+  - DHCP discovery
+  - Global Caché UDP beacon discovery
+- Automatic detection of infrared-capable ports
+- One infrared entity per infrared-capable port
+- Support for:
+  - Pronto Hex infrared commands
+  - Raw infrared timing sequences
+- Runtime refresh of device capabilities after hardware-side configuration changes
+- Diagnostics support
+- Repairs support for connectivity and configuration issues
+
+## Requirements
+
+- A reachable Global Caché iTach IP2IR device on the local network
+- Home Assistant network access to TCP port `4998`
+- Infrared emitters connected to the desired output ports
+
+## Configuration
+
+### Automatic discovery
+
+If the iTach IP2IR device is connected to the network, Home Assistant should discover it automatically.
+
+When discovered:
+
+1. Open the notification in Home Assistant.
+2. Confirm the device.
+3. Complete setup.
+
+### Manual configuration
+
+To add the integration manually:
+
+1. Go to **Settings** → **Devices & services**.
+2. Select **Add Integration**.
+3. Search for **Global Caché iTach IP2IR**.
+4. Enter:
+   - Hostname or IP address
+   - TCP port (normally `4998`)
+
+## Infrared entities
+
+The integration creates one `infrared` entity for each infrared-capable output port detected on the device.
+
+Entity names depend on the detected port type:
+
+- `IR Port X`
+- `IR Blaster Port X`
+
+Only ports that advertise infrared transmission capability are exposed.
+
+## Sending infrared commands
+
+Infrared commands can be sent using the `infrared.send_command` action.
+
+Example:
+
+```yaml
+action: infrared.send_command
+target:
+  entity_id: infrared.ir_port_1
+data:
+  command:
+    - "0000 006D 0022 0002 0157 00AC 0015 0016"
+```
+
+## Reconfiguring infrared ports
+
+The iTach IP2IR device can be reconfigured outside of Home Assistant.
+
+If the hardware configuration changes:
+
+1. Open the integration.
+2. Select **Configure**.
+3. Use **Refresh infrared ports**.
+
+The integration will re-query the device and synchronize entity availability with the currently advertised capabilities.
+
+This avoids removing and re-adding the integration after device-side changes.
+
+## Diagnostics
+
+The integration supports diagnostics downloads from the device page.
+
+Diagnostics include:
+
+- Device identification
+- Detected infrared-capable ports
+- Connection information
+- Entity mapping information
+
+Sensitive information is redacted automatically.
+
+## Troubleshooting
+
+### Device not discovered
+
+- Verify the device and Home Assistant are on the same network.
+- Verify UDP discovery traffic is not blocked.
+- Verify the device is powered on.
+
+### Cannot connect
+
+- Verify the IP address or hostname.
+- Verify TCP port `4998` is reachable.
+- Verify no firewall rules block Home Assistant.
+
+### No infrared entities created
+
+The integration only creates entities for ports that advertise infrared transmission capability.
+
+Verify:
+- Infrared-capable ports are enabled on the device
+- The hardware configuration is correct
+- The integration has been refreshed after reconfiguration
+
+## Actions
+
+### infrared.send_command
+
+Send an infrared command to an infrared entity.
+
+#### Action data
+
+| Field | Description |
+|---|---|
+| `command` | Infrared command payload |
+| `repeat` | Number of repeats |
+| `delay_secs` | Delay between repeats |
+
+## Notes
+
+This integration does not learn infrared commands.
+
+Infrared command learning must be performed using external hardware or external software tools.
