Requirements

• SmartHomeNG
• homebridge

Installation

Install nodejs >=14.18.1

See NodeJS website for details depending on your OS.

Install libavahi-compat-libdnssd-dev lib

For me i needed these libraries to be installed for my homebridge to work. See their Homepage for installation instructions.
Below is what i did on my Debian Bullseye installation:

sudo apt install libavahi-compat-libdnssd-dev

Install homebridge >=1.3.5 from NPM repository

npm install -g homebridge --unsafe-perm

Install this plugin from NPM repository

npm install -g homebridge-smarthomeng --unsafe-perm

Configuration

If you already have a working homebridge installation just add the platform section into your existing config. If you are a new homebridge user you have to create a config.json file in the .homebridge directory. You'll find that directory in your home folder.

Platform configuration

The following parameters are available to configure the plugin as platform in homebridge.

Parameter	Possible values	Mandatory	Description
platform	Any <string>	Yes	Internal name of your platform
name	Any <string>	Yes	Visible name in HomeKit

port	Port <number>	No	Listening port of websocket module. Default is 2424
tls	<boolean>	No	Should TLS encryption be used. Defaults is 'false'

Example configuration:

{
    "platform": "SmartHomeNG",
    "name": "SmartHomeNG",
    "host": "smarthome.my.domain",
    "port": 2425,
    "tls": true,
}

Common accessories characteristics

The following characteristics are valid for all accessories:

Parameter	Possible values	Mandatory	Description

Doorbell

A doorbell is an accessory that simply sends a message to all devices enrolled in the home that someone rang the doorbell. HomeKit displays a message that "This accessory is not currently supported by the Home app.". Further investigation is needed, but for now it still works.

Characteristics in addition to common characteristics

    "name": "Main door",
    "SinglePress": "Technik.Asterisk.Klingel"
}

Fan

For now this accessory only supports turning the fan on and off. Further improvements are possible, but i don't have the needed hardware for testing.

Characteristics in addition to common characteristics

Parameter	Possible values	Mandatory	Description
Active	<item>	Yes	SHNG item to set and get the fan state

Example:

{
    "type": "Fan",
    "name": "Fan bathroom",
    "Active": "OG.Bad.Ventilator"
}

LightBulb

TODO

Occupancy sensor

Characteristics in addition to common characteristics

Parameter	Possible values	Mandatory	Description
OccupancyDetected	<item>	Yes	SHNG item to monitor for presence

Example:

{
    "type": "OccupancySensor",
    "name": "Presence bathroom",
    "manufacturer": "Preussen",
    "model": "Motion 360 KNX",
    "OccupancyDetected": "OG.Bad.Praesenz"
}

Motion sensor

This sensor is tripped if it detects motion in a room.

Characteristics in addition to common characteristics

Parameter	Possible values	Mandatory	Description
MotionDetected	<item>	Yes	SHNG item to monitor for motion

Example:

{
    "type": "OccupancySensor",
    "name": "Presence bathroom",
    "OccupancyDetected": "EG.Flur.Bewegung"
}

Contact sensor

This sensor shows the open / closed state of a contact (door, window, generic ...).

Characteristics in addition to common characteristics

Parameter	Possible values	Mandatory	Description
ContactState	<item>	Yes	SHNG item to monitor for contact

Example:

{
    "type": "ContactSensor",
    "name": "Window kitchen",
    "ContactState": "EG.Kueche.Fenster"
}

Switch

This accessory can monitor and change the on/off state of something. It is very similar to an outlet.

Parameter	Possible values	Mandatory	Description
On	<item>	Yes	SHNG item to switch something on or off

Example:

{
    "type": "Switch",

Parameter	Possible values	Mandatory	Description
CurrentTemperature	<item>	Yes	SHNG item to monitor for temperature

Example:

{
    "type": "TemperatureSensor",
    "name": "Temperature WC",
    "CurrentTemperature": "EG.WC.Temperatur"
}

### Thermostat TODO

WindowCovering

In addition to the common characteristics the following are available.

Mandatory:

{
	"CurrentPosition": "EG.Buero.Rolladen.Position",
	"TargetPosition": "EG.Buero.Rolladen.ZielPosition",
}

The current moving state and direction is automatically derived from the difference between the current and target position.

Optional:

{
	"CurrentPositionMin": 0,
	"CurrentPositionMax": 255,
	"CurrentPositionInverted": true,
	"TargetPositionMin": 0,
	"TargetPositionMax": 255,
	"TargetPositionInverted": true
}

HomeKit works with values between 0 and 100 where 0 is completely closed and 100 is open.
My KNX installation, as example, needs values between 0 and 255 where 255 is completely closed and 0 is open.
The above optional parameters allow you to specify the neede range for your device. If needed the values can be inverted at the same time. The plugin then transposes the values in both directions.
