# ekey Binding

This binding connects to [ekey](https://ekey.net/) converter UDP (CV-LAN) using the RARE/MULTI/HOME protocols.

## Supported Things

This binding only supports one thing type:

| Thing       | Thing Type | Description                                 |
|-------------|------------|---------------------------------------------|
| cvlan | Thing      | Represents a single ekey converter UDP |

## Thing Configuration

The binding uses the following configuration parameters.

| Parameter | Description                                                    |
|-----------|----------------------------------------------------------------|
| ipAddress | IPv4 address of the eKey udp converter.  A static IP address is recommended.|
| port      | The port as configured during the UDP Converter configuration.  e.g. 56000 (Binding default)     |
| protocol  | Can be RARE, MULTI or HOME depending on what the system supports. Binding defaults to RARE  |
| delimiter | The delimiter is also defined on the ekey UDP converter - use the ekey configuration software to determine which delimiter is used or to change it.  Binding default is `_` (underscore)  |

## Channels

| Channel ID | Item Type | Protocol | Description                                                                                                                                                                                                                                           | Possible Values                      |
