# Onkyo Binding

This binding integrates the Onkyo AV receivers.

## Introduction

Binding should be compatible with Onkyo AV receivers which support ISCP (Integra Serial Control Protocol) over Ethernet (eISCP).

## Supported Things

This binding supports only one thing: The Onkyo AV receiver.
All supported Onkyo devices are registered as an audio sink in the framework.

## Discovery

This binding can discover the supported Onkyo AV receivers.
At the moment only the following models are supported:

- HT-RC440
- HT-RC560
- TX-NR414
- TX-NR474
- TX-NR509
- TX-NR515
- TX-NR525

- TX-NR575
- TX-NR575E
    TX-NR609
- TX-NR616
- TX-NR626
- TX-NR636
- TX-NR646
- TX-NR656
- TX-NR676
- TX-NR686

- TX-NR727
- TX-NR737
- TX-NR747

- TX-NR807
- TX-NR809
- TX-NR818
- TX-NR828
- TX-NR838
- TX-NR3007
- TX-RZ900

## Binding Configuration

The binding can auto-discover the Onkyo AVRs present on your local network.
The auto-discovery is enabled by default.
To disable it, you can create a file in the services directory called onkyo.cfg with the following content:

```text
org.openhab.onkyo:enableAutoDiscovery=false
```

This configuration parameter only controls the Onkyo AVR auto-discovery process, not the openHAB auto-discovery.
Moreover, if the openHAB auto-discovery is disabled, the Onkyo AVR auto-discovery is disabled too.

The binding has the following configuration options, which can be set for "binding:onkyo":

| Parameter   | Name         | Description                                                              | Required |
|-------------|--------------|--------------------------------------------------------------------------|----------|
| callbackUrl | Callback URL | URL to use for playing notification sounds, e.g. <http://192.168.0.2:8080> | no       |

When an Onkyo receiver is used as an audio sink, the receiver connects to openHAB to get the audio stream.
By default, the binding sends the URL for getting the audio stream based on the Primary Address (Network Settings configuration) and the openHAB HTTP port.
Sometimes it is necessary to use the Callback URL to override the default, such as when using a reverse proxy or with some Docker implementations.

## Thing Configuration

The Onkyo AVR thing requires the ip address and the port to access it on.
In the code `avr-livingroom` refers to the user defined unique id of your Onkyo device.
A second device could be called avr2.
In the thing file, this looks e.g. like

Model specific

```text
onkyo:TX-NR818:avr-livingroom [ipAddress="192.168.1.100", port=60128]
```

or

Generic model

```text
onkyo:onkyoAVR:avr-livingroom [ipAddress="192.168.1.100", port=60128]
```

Optionally you can specify the refresh interval by `refreshInterval` parameter.

```text
onkyo:onkyoAVR:avr-livingroom [ipAddress="192.168.1.100", port=60128, refreshInterval=30]
```

Maximum volume level can also be configured by `volumeLimit` parameter.
This prevent setting receiver volume level too high, which could damage your speakers or receiver.

```text
onkyo:onkyoAVR:avr-livingroom [ipAddress="192.168.1.100", port=60128, volumeLimit=50]
```

Binding then automatically scale the volume level in both directions (100% = 50 = 100%).

You can also change the way volume scaling works.
This can be necessary if your receiver uses a different scaling system than 0-100.
You can specify a decimal number that acts as the coefficient for scaling.
See below for a few examples:

| Value  | Description                                          | Value for 100%   |
|--------|------------------------------------------------------|------------------|
| 1      | Default, don't scale                                 |              100 |
| 2      | For receivers that support 0.5 increments in volume  |              200 |
| 0.8    | For receivers that go from 0-80                      |               80 |
| 0.5    | For receivers that go from 0-50                      |               50 |

Note that this is applied after the volume limiting took place.

```text
onkyo:onkyoAVR:avr-livingroom [ipAddress="192.168.1.100", port=60128, volumeScale=2]
```

The binding will send value 200 for maximum volume to the receiver.

## Channels

The Onkyo AVR supports the following channels (some channels are model specific):

| Channel Type ID           | Item Type | Description                                                                                                     |

## Rule Actions

This binding includes a rule action which allows to send raw eISCP messages to the receiver.
The rule action can be used to send commands to the receiver that are not supported by channels.
There is a separate instance for each receiver, which can be retrieved through

```java
val onkyoActions = getActions("onkyo","onkyo:onkyoAVR:avr-livingroom")
```

where the first parameter always has to be `onkyo` and the second (`onkyo:onkyoAVR:avr-livingroom`) is the Thing UID of the broker that should be used.
Once this action instance is retrieved, you can invoke the `onkyoActions.sendRawCommand(String action, String value)` method on it:

```java
onkyoActions.sendRawCommand("CTL", "UP")
```

This command for instance increases the volume for the center channel.
For a description of all commands you can e.g. search [this GitHub project](https://github.com/miracle2k/onkyo-eiscp/tree/master/commands/main).

Also note that when sending multiple commands there has to be a `Thread::sleep(100)` in between the commands because the action does not wait for a response from the receiver.
