# EnOcean Binding

The EnOcean binding connects openHAB to the EnOcean ecosystem.

The binding uses an EnOcean gateway to retrieve sensor data and control actuators.
For _bidirectional_ actuators it is even possible to update the openHAB item state if the actuator gets modified outside of openHAB.
This binding has been developed on an USB300 gateway and was also tested with an EnOceanPi.
As this binding implements a full EnOcean stack, we have full control over these gateways.
This binding can enable the repeater function (level 1 or 2) of these gateways and retrieve detailed information about them.

## Concepts/Configuration

First of all you have to configure an EnOcean transceiver (gateway).
A directly connected USB300 can be auto discovered, an EnOceanPi has to be added manually to openHAB.
Both gateways are represented by an _EnOcean gateway_ in openHAB.
If you want to place the gateway for better reception apart from your openHAB server, you can forward its serial messages over TCP/IP (_ser2net_).
In this case you have to define the path to the gateway like this rfc2217://x.x.x.x:3001. When using _ser2net_ make sure to use _telnet_  instead of _raw_ in the _set2net_ config file.
If everything is running fine you should see the _base id_ of your gateway in the properties of your bridge.

Another way to improve sending and reception reliability is to setup a wired connection.
In this case you directly connect to your RS485 EnOcean bus (use USB connection of an Eltako FAM14 e.g.).
However communication on RS485 bus is mostly done with an older ESP2 protocol which does not support advanced telegrams like VLD.
Furthermore you have to be aware that not all radio telegrams are published on the bus.

The vast majority of EnOcean messages are sent as broadcast messages without an explicit receiver address.
However each EnOcean device is identified by an unique id, called EnOceanId, which is used as the sender address in these messages.
To receive messages from an EnOcean device you have to determine its EnOceanId and add an appropriate thing to openHAB.

If the device is an actuator which you want to control with your gateway from openHAB, you also have to create an unique sender id and announce it to the actuator (_teach-in_).
For security reasons you cannot choose a random id, instead each gateway has 127 unique ids build in, from which you can choose.
A SenderId of your gateway is made up its base id and a number between 1 and 127.
This number can be chosen manually or the next free/unused number can be determined by the binding.

¹ Not all channels are supported by all devices, it depends which specific EEP type is used by the device, all thing types additionally support `rssi`, `repeatCount` and `lastReceived` channels

² These are just examples of supported devices

Furthermore following supporting EEP family is available too: A5-11, types 0x03 (rollershutter position status), 0x04 (extended light status) and D0-06 (battery level indication).

A `rockerSwitch` is used to receive messages from a physical EnOcean Rocker Switch.
A `classicDevice` is used for older EnOcean devices which react only on rocker switch messages (like Opus GN-A-R12V-SR-4).
As these devices do not send their current status, you have to add additional listener channels for each physical Rocker Switch to your thing.
In this way you can still sync your item status with the physical status of your device whenever it gets modified by a physical rocker switch.
The classic device simulates a physical Rocker Switch.
Per default the classic device uses the channel A of the simulated rocker switch.
If you want to use channel B you have to use virtualRockerswitchB in conjunction with rules to send commands.

## Pairing

Most of the EnOcean devices can be automatically created and configured as an openHAB thing through the discovery service.
The EnOcean protocol defines a so called "teach-in" process to announce the abilities and services of an EnOcean device and pair devices.
To pair an EnOcean device with its openHAB thing representation, you have to differentiate between sensors and actuators.

### Sensors

To pair a sensor with its thing, you first have to start the discovery scan for this binding.
Then press the "teach-in" button of the sensor.
The sensor sends a teach-in message which contains the information about the EEP and the EnOceanId of the sensor.
If the EEP is known by this binding the thing representation of the device is created.
The corresponding channels are created dynamically, too. 

### Actuators
 
If the actuator supports UTE teach-in, the corresponding thing can be created and paired automatically.
First you have to **start the discovery scan for a gateway**.
Then press the teach-in button of the actuator.
If the EEP of the actuator is known, the binding sends an UTE teach-in response with a new SenderId and creates a new thing with its channels.

This binding supports so called smart acknowlegde (SMACK) devices too.
Before you can pair a SMACK device you have to configure your gateway bridge as a SMACK postmaster.
If this option is enabled you can pair up to 20 SMACK devices with your gateway.

Communication between your gateway and a SMACK device is handled through mailboxes.
A mailbox is created for each paired SMACK device and deleted after teach out.
You can see the paired SMACK devices and their mailbox index in the gateway properties.
SMACK devices send periodically status updates followed by a response request.
Whenever such a request is received a `requestAnswer` event is triggered for channel `statusRequestEvent`.
Afterwards you have 100ms time to recalculate your items states and update them.
A message with the updated item states is built, put into the corresponding mailbox and automatically sent upon request of the device.
Pairing and unpairing can be done through a discovery scan.
The corresponding thing of an unpaired device gets disabled, you have to delete it manually if you want to.

If the actuator does not support UTE teach-ins, you have to create, configure and choose the right EEP of the thing manually.
It is important to link the teach-in channel of this thing to a switch item.
Afterwards you have to **activate the pairing mode of the actuator**.
Then switch on the teach-in item to send a teach-in message to the actuator.
If the pairing was successful, you can control the actuator and unlink the teach-in channel now.
The content of this teach-in message is device specific and can be configured through the teach-in channel.

To pair a classicDevice with an EnOcean device, you first have to activate the pairing mode of the actuator.
Then switch the virtualRockerSwitchA On/Off.

Each EnOcean gateway supports 127 unique SenderIds.
The SenderId of a thing can be set manually or determined automatically by the binding.
In case of an UTE teach-in the next unused SenderId is taken automatically.
To set this SenderId to a specific one, you have to use the nextSenderId parameter of your gateway.

## Thing Configuration

The pairing process of an openHAB thing and an EnOcean device has to be triggered within the UI.
Therefore if you do not want to use the UI, a mixed mode configuration approach has to be done.
To determine the EEP and EnOceanId of the device and announce a SenderId to it, you first have to pair an openHAB thing with the EnOcean device.
Afterwards you can delete this thing and manage it with its necessary parameters through a configuration file.
If you change the SenderId of your thing, you have to pair again the thing with your device.

¹ multiple values possible, EEPs have to be of different EEP families.
If you want to receive messages of your EnOcean devices you have to set **the enoceanId to the EnOceanId of your device**.

## Channels

Items linked to bi-directional actuators (actuator sends status messages back) should always disable the `autoupdate`.
This is especially true for Eltako rollershutter, as their position is calculated out of the current position and the moving time.

## Channel Configuration

Some channels can be configured with parameters.

| Channel type  | Parameter      | Meaning                                                              | Possible values                                                                                                                     |

Possible declaration in Thing DSL:

```xtend
Thing centralCommand 11223344 "Light" @ "Living room" [ enoceanId="11223344", senderIdOffset=15, sendingEEPId="A5_38_08_02", receivingEEPId="A5_38_08_02" ] {
    Channels:
        Type teachInCMD : teachInCMD [ teachInMSG="E0400D80" ]
        Type dimmer : dimmer [ rampingTime=0 ]
}
```

## Rules and Profiles

The rockerSwitch things use _system:rawrocker_ channel types.
So they trigger _DIR1[/2]_\__PRESSED_ and DIR1[/2]_\__RELEASED_ events.
These channels can be directly linked to simple items like Switch, Dimmer or Player with the help of _profiles_.
If you want to do more advanced stuff, you have to implement rules which react to these events

```xtend
rule "Advanced rocker rule"
when
    Channel 'enocean:rockerSwitch:gtwy:AABBCC00:rockerswitchA' triggered DIR1_PRESSED
then
    // do some advanced stuff
end
```

```

## Generic Things

If an EnOcean device uses an unsupported EEP or _A5-3F-7F_, you have to create a `genericThing`.
Generic things support all channels like switch, number, string etc as generic channels.
However you have to specify how to convert the EnOcean messages of the device into openHAB state updates and how to convert the openHAB commands into EnOcean messages.
These conversion functions can be defined with the help of transformation functions like MAP.

|Thing type                       | Parameter         | Meaning                    | Possible Values |
|---------------------------------|-------------------|----------------------------|---|
| genericThing                    | senderIdOffset    |                            | 1-127 |
|                                 | enoceanId         | EnOceanId of device this thing belongs to | hex value as string |
|                                 | sendingEEPId      | EEP used for sending msg   | F6_FF_FF, A5_FF_FF, D2_FF_FF |
|                                 | receivingEEPId    | EEP used for receiving msg | F6_FF_FF, A5_FF_FF, D2_FF_FF |
|                                 | broadcastMessages |                            | true, false |
|                                 | suppressRepeating |                            | true, false |

Supported channels: genericSwitch, genericRollershutter, genericDimmer, genericNumber, genericString, genericColor, genericTeachInCMD.
You have to define the transformationType (e.g. MAP) and transformationFunction (e.g. for MAP: file name of mapping file) for each of these channels. 

For an inbound transformation (EnOcean message => openHAB state) you receive the channel id and the EnOcean data in hex separated by a pipe.
Your transformation function has to return the openHAB State type and value separated by a pipe.
If you want to use a mapping transformation, your mapping file has to look like this for a genericThing using EEP F6_FF_FF:

```
ChannelId|EnoceanData(Hex)=openHABState|Value
genericSwitch|70=OnOffType|ON
genericSwitch|50=OnOffType|OFF
genericRollershutter|70=PercentType|0
genericRollershutter|50=PercentType|100
```

For an outbound transformation (openHAB command => EnOcean message) you receive the channel id and the command separated by a pipe.
Your transformation function has to return the payload of the EnOcean message.
You do not have to worry about CRC and header data.
If you want to use a mapping transformation, your mapping file has to look like this for a genericThing using EEP A5_FF_FF:

```
ChannelId|openHABCommand=EnoceanData(Hex)
genericSwitch|ON=01000009
genericSwitch|OFF=01000008
```
