# OpenWebNet (BTicino/Legrand) Binding

This binding integrates BTicino / Legrand MyHOME&reg; BUS and ZigBee wireless (MyHOME_Play&reg;) devices using the [OpenWebNet](https://en.wikipedia.org/wiki/OpenWebNet) protocol.

The binding supports:

- both wired BUS/SCS (MyHOME) and wireless setups (MyHOME ZigBee). The two networks can be configured simultaneously
- auto discovery of BUS/SCS IP and ZigBee USB gateways; auto discovery of devices
- commands from openHAB and feedback (events) from BUS/SCS and wireless network

## Discovery

Gateway and Things discovery is supported by this binding.

### BUS/SCS Discovery

- BUS Gateway automatic discovery will work only for newer gateways supporting UPnP: F454, MyHOMEServer1, MH201, MH202, MH200N, MyHOME_Screen 10.
For other gateways you can add them manually, see [Thing Configuration](#thing-configuration) below.
- After gateway is discovered and added a connection with default password (`12345`) is tested first: if it does not work the gateway will go offline and an error status will be set. A correct password must then be set in the gateway Thing configuration otherwise the gateway will not become online.
- Once the gateway is online, a second Inbox Scan will discover BUS devices
- BUS/SCS Dimmers must be ON and dimmed (30%-100%) during a Scan, otherwise they will be discovered as simple On/Off switches
    - *KNOWN ISSUE*: In some cases dimmers connected to a F429 Dali-interface are not automatically discovered
- CEN/CEN+ Scenario Control devices will be discovered by activation only. See [discovery by activation](#discovery-by-activation) for details. After confirming a discovered CEN/CEN+ device from Inbox, activate again its scenario buttons to add button channels automatically

#### Discovery by Activation

BUS devices can also be discovered if activated while an Inbox Scan is active: start a new Scan, wait 15-20 seconds and then _while the Scan is still active_, activate the physical device (for example dim the dimmer) to have it discovered by the binding.

If a device cannot be discovered automatically it's always possible to add it manually, see [Configuring Devices](#configuring-devices).

### ZigBee Discovery

- The ZigBee USB Gateway must be inserted in one of the USB ports of the openHAB computer before a discovery is started
- ***IMPORTANT NOTE:*** As for other openHAB bindings using the USB/serial ports, on Linux the `openhab` user must be member of the `dialout` group to be able to use USB/serial port; set the group with the following command:

    ```
    $ sudo usermod -a -G dialout openhab
    ```

    The user will need to logout and login to see the new group added. If you added your user to this group and still cannot get permission, reboot Linux to ensure the new group permission is attached to the `openhab` user.
- Once the ZigBee USB Gateway is added and online, a second Inbox Scan will discover devices connected to it. Because of the ZigBee radio network, device discovery will take ~40-60 sec. Be patient!
- Wireless devices must be part of the same ZigBee network of the ZigBee USB Gateway to discover them. Please refer to [this video by BTicino](https://www.youtube.com/watch?v=CoIgg_Xqhbo) to setup a ZigBee wireless network which includes the ZigBee USB Gateway
- Only powered wireless devices part of the same ZigBee network and within radio coverage of the ZigBee USB Gateway will be discovered. Unreachable or not powered devices will be discovered as *GENERIC* devices and cannot be controlled
- Wireless control units cannot be discovered by the ZigBee USB Gateway and therefore are not supported

## Thing Configuration

### Configuring BUS/SCS Gateway

Configuration parameters are:

- `host` : IP address / hostname of the BUS/SCS gateway (`String`, *mandatory*)
   - Example: `192.168.1.35`
- `port` : port (`int`, *optional*, default: `20000`)
- `passwd` : gateway password (`String`, *required* for gateways that have a password. Default: `12345`)
   - Example: `abcde` or `12345`
   - if the BUS/SCS gateway is configured to accept connections from the openHAB computer IP address, no password should be required
   - in all other cases, a password must be configured. This includes gateways that have been discovered and added from Inbox: without a password configured they will remain OFFLINE
- `discoveryByActivation`: discover BUS devices when they are activated also when a device scan is not currently active (`boolean`, *optional*, default: `false`). See [Discovery by Activation](#discovery-by-activation).

Alternatively the BUS/SCS Gateway thing can be configured using the `.things` file, see `openwebnet.things` example [below](#full-example).

### Configuring Wireless ZigBee USB Gateway

Configuration parameters are:

- `serialPort` : the serial port where the ZigBee USB Gateway is connected (`String`, *mandatory*)
    - Examples: `/dev/ttyUSB0` (Linux/RaPi), `COM3` (Windows)

Alternatively the ZigBee USB Gateway thing can be configured using the `.things` file, see `openwebnet.things` example [below](#full-example).

### Configuring Devices

Devices can be discovered automatically using an Inbox Scan after a gateway has been configured and connected.

For any manually added device, you must configure:

- the associated gateway Thing (`Parent Bridge` menu)
- the `where` configuration parameter (`OpenWebNet Address`): this is the OpenWebNet address configured for the device in the BTicino/Legrand system. This address can be found either on the device itself (Physical configuration, using jumpers in case of BUS) or through the MyHOME_Suite software (Virtual configuration). The address can have several formats depending on the device/system:
    - example for BUS/SCS system, address Point-to-point with Area (A) and Light-point (PL):
        - light device A=`2` (Area 2), PL=`4` (Light-point 4) --> `where="24"`
        - light device A=`03`, PL=`11` on local bus --> `where="0311#4#01"`
        - CEN scenario A=`05`, PL=`12` --> `where="0512"`
        - CEN+ scenario `5`: add a `2` before --> `where="25"`
        - Dry Contact or IR Interface `99`: add a `3` before --> `where="399"`
    - example for ZigBee devices: `where=765432101#9`. The ID of the device (ADDR part) is usually written in hexadecimal on the device itself, for example `ID 0074CBB1`: convert to decimal (`7654321`) and add `01#9` at the end to obtain `where=765432101#9`. For 2-unit switch devices (`zb_on_off_switch2u`), last part should be `00#9`.
 

#### Configuring Thermo

In BTicino MyHOME Thermoregulation (WHO=4) each **zone** has associated a thermostat, additional temperature sensors (optional), actuators and heating/conditioning valves. A zone is associated to at least one thermostat and one actuator.

Thermo zones can be configured defining a `bus_thermo_zone` Thing for each zone with the following parameters:

- the `where` configuration parameter (`OpenWebNet Address`):
    - example BUS/SCS zone `1` --> `where="1"` 
- the `standAlone` configuration parameter (`boolean`, default: `true`): identifies if the zone is managed or not by a Central Unit (4 or 99 zones). `standAlone=true` means no Central Unit is present in the system.

Temperature sensors can be configured defining a `bus_thermo_sensor` Thing with the following parameters:

- the `where` configuration parameter (`OpenWebNet Address`):
    - example sensor `5` of external zone `00` --> `where="500"`
    - example: slave sensor `3` of zone `2` --> `where="302"`

The (optional) Central Unit can be configured defining a `bus_themo_cu` Thing.

#### Configuring Auxiliary (AUX)

BUS Auxiliary commands (WHO=9) can be used to send on the BUS commands to control, for example, external devices or a BTcino Alarm system. 

To control a BTicino alarm system the alarm unit should be configured for example as follows:

Antitheft -> Automations -> then toggle the Event option -> then select OPEN code

- Type in the AUX command you want to set, e.g.\*9\*1\*4\## (where=4)
- Type in the associated Open Web Net code you want to execute, e.g.\*5\*8*#1234## (engage alarm on zones 1,2,3,4).

Please note that receiving AUX messages originating from the bus is not supported yet, only sending messages to the bus is supported.

### Notes on channels

####  `shutter` position

For Percent commands and position feedback to work correctly, the `shutterRun` Thing config parameter must be configured equal to the time (in ms) to go from full UP to full DOWN.
It's possible to enter a value manually or set `shutterRun=AUTO` (default) to calibrate `shutterRun` automatically: in this case a *UP >> DOWN >> Position%* cycle will be performed automatically the first time a Percent command is sent to the shutter.

- if `shutterRun` is not set, or is set to `AUTO` but calibration has not been performed yet, then position estimation will remain `UNDEF` (undefined)
- if `shutterRun` is wrongly set higher than the actual runtime, then position estimation will remain `UNDEF`: try to reduce shutterRun until you find the right value
- before adding/configuring roller shutter Things it is suggested to have all roller shutters `UP`, otherwise the Percent command won’t work until the roller shutter is fully rolled up
- if OH is restarted the binding does not know if a shutter position has changed in the meantime, so its position will be `UNDEF`. Move the shutter all `UP`/`DOWN` to synchronize again its position with the binding
- the shutter position is estimated based on UP/DOWN timing: an error of ±2% is normal

#### CEN/CEN+ channels

CEN/CEN+ are [TRIGGER channels](https://www.openhab.org/docs/configuration/rules-dsl.html#channel-based-triggers]): they handle events and do not have a state.

A powerful feature is to be able to assign CEN or CEN+ commands to your physical wall switches and use the events they generate to trigger rules in openHAB: this way openHAB becomes a very powerful scenario manager activated by physical BTicino switches.
See [openwebnet.rules](#openwebnet-rules) for an example on how to define rules that trigger on CEN/CEN+ buttons events.

It's also possible to send *virtual press* events on the BUS, for example to enable the activation of MH202 scenarios from openHAB.
See [openwebnet.sitemap](#openwebnet-sitemap) & [openwebnet.rules](#openwebnet-rules) sections for an example on how to use the `virtualPress` action connected to a pushbutton on a sitemap.

- channels are named `button#X` where `X` is the button number on the Scenario Control device
- in the .thing file configuration you can specify the `buttons` parameter to define a comma-separated list of buttons numbers [0-31] configured for the scenario device, example: `buttons=1,2,4`
- possible events are:
    - for CEN:
        - `START_PRESS` - sent when you start pressing the button
        - `SHORT_PRESS` - sent if you pressed the button shorter than 0,5sec (sent at the moment when you release it)
        - `EXTENDED_PRESS` - sent if you keep the button pressed longer than 0,5sec; will be sent again every 0,5sec as long as you hold pressed (good for dimming rules)
        - `RELEASE_EXTENDED_PRESS` - sent once when you finally release the button after having it pressed longer than 0,5sec
    - for CEN+:
        - `SHORT_PRESS` - sent if you pressed the button shorter than 0,5sec (sent at the moment when you release it)
        - `START_EXTENDED_PRESS` - sent once as soon as you keep the button pressed longer than 0,5sec
        - `EXTENDED_PRESS` - sent after `START_EXTENDED_PRESS` if you keep the button pressed longer; will be sent again every 0,5sec as long as you hold pressed (good for dimming rules)
        - `RELEASE_EXTENDED_PRESS` - sent once when you finally release the button after having it pressed longer than 0,5sec

####  `mode` for values WEEKLY and SCENARIO (Central Unit)

There are three WEEKLY and sixteen SCENARIO programs defined for the Central Unit.

In order to activate one of them you have to use two different channels:

- with `mode` you can set the mode (`WEEKLY` or `SCENARIO`)
- with `weeklyProgram` (if `WEEKLY` was setted) or with `scenarioProgram` (if `SCENARIO` was setted) you can set the program number

Example: if you want to activate SCENARIO #9 you have to set `mode` = `SCENARIO` and `scenarioProgram` = `9`.
