• config your devices on KNX bus (maybe with ETS6) learn ETS6 Ecampus

• needed module : a simple KNX net contain 3 device

  1. actuator

  2. switch

  3. Gateway (for communicate with OH & Program KNX devices)

     this is a KNX IP interface or router

• read OH documentaition : KNX - Bindings | openHAB

• make sure that OH host connected to Gateway (maybe ping it with ip address on host)

1. add [knx binding](KNX - Bindings | openHAB) addon to your OpenHab panel

    Settings -> Bindings -> (+) (add) KNX Binding

            for connection to KNX bus you need 2 Things in your OH

2. KNX/IP Gateway (your gateway)

3. KNX Device (virtual definition of a KNX device on KNX bus)

this is a KNX IP interface or router

for adding new gateway in your OH Things with administrator permission goto :

Settings -> Things -> (+) (add) KNX Binding -> KNX/IP Gateway

this is an example

UID: knx:ip:ed1a7ff380
label: myKNXGatewayTest
thingTypeUID: knx:ip
configuration:
  useNAT: true
  readRetriesLimit: 3
  ipAddress: 192.168.1.181
  autoReconnectPeriod: 60
  type: TUNNEL
  localSourceAddr: 0.0.0
  readingPause: 50
  portNumber: 3671
  responseTimeout: 10
location: secondFloor

• Local Device Address (localSourseAddr) : 0.0.0 let OH decide what address to use - this is you gateway Address on KNX bus

• type : depend on your KNX/IP gateway specs

• ipAddress : your gateway ipAddress on LAN Network

this is an addressable basic KNX device

for adding new device in your OH Things with administrator permission goto :

Settings -> Things -> (+) (add) KNX Binding -> KNX Device

this is an example

UID: knx:device:a2300e6ac9
label: myKNXDeviceTest
thingTypeUID: knx:device
configuration:
  pingInterval: 600
  address: 1.1.100
  readInterval: 0
  fetch: false
bridgeUID: knx:ip:ed1a7ff380
location: secondFloor

• bridgeUID (Parent Bridge) : this will represent your KNX/IP Gateway that you create in previous part

• address: your KNX/IP Gateway address on KNX bus

Channels could be a represent of a Group address in KNX bus

for adding Channels to a KNX device on OH with administrator permission goto :

Settings -> Things -> myKNXDeviceTest -> Channels -> Add Channel

you need to specify

• Channel Identifier : a manual code

• Label : blablabla

• Channel Type : According to your KNX device specs and configs on KNX bus

• Configuration : may add groupAddressed and other configs (E.g., 0/2/1)

example for a simple Switch :

this code is from knx device -> code

channels:
  - id: "Channel Identifier"
    channelTypeUID: knx:switch
    label: "Channel Identifier"
    description: "blablabla"
    configuration:
      ga: 0/0/1
  - id: "Channel Identifier2"
    channelTypeUID: knx:switch
    label: "bla"
    description: "bla"
    configuration:
      ga: 0/0/2

Settings -> Things -> myKNXDeviceTest -> Channels -> (Channel Identifier) -> Add Link to Item...

ip gateway like ABB IPS/S 3.1.1 must restart to get new ip address from DHCP
