[SOLVED] Room Automation using OpenHAB, KNXD and Raspberry Pi 3

harshita · June 28, 2018, 2:24pm

I am building a room automation system which has just lights and rollershutters.
I started with only lights for now but I am unable to configure OpenHAB.
I am able to read and write the bus which means my KNXD is working.
But I am unable to configure openHAB.

My openhab.cfg file on /etc/openhab/configurations path is as follows:

knx:ip=192.168.1.22
knx:busaddr=1.1.9
knx:ignorelocalevents=true
knx:type=ROUTER
knx:serialPort=/dev/ttyUSB0

My Items file:
Group Lights
Switch Left_Lights "Left Lights"(Lights) { knx="<1/1/51" }
Switch Right_Lights "Right Lights" (Lights) { knx="<1/1/52" }
Switch Centre_Lights "Centre Lights" (Lights) { knx="<1/1/53" }
Switch Other_Lights "Other Lights" (Lights) { knx="<1/1/54" }

My rules file:
sitemap default label="default"
{ Frame label = "F1 406" {
Switch item=Left_Lights label="Left Lights" mappings=[1="ON",0="OFF"]
Group item = Lights

Switch item=Right_Lights label="Right Lights" mappings=[1="ON",0="OFF"]
Group item = Lights

Switch item=Centre_Lights label="Centre Lights" mappings=[1="ON,0="OFF"] Group item = Lights

Switch item=Other_Lights label="Other Lights" mappings=[1="ON",0="OFF"] Group item = Lights
}
}

My rules file:

org.eclipse.smarthome.core.persistence
org.eclipse.smarthome.core.library.types
org.eclipse.smarthome.core.library.items
org.eclipse.smarthome.model.script.actions

rule "Switch ON Left Lights 1"
when
     Item Left_Lights changed [from OFF] [to ON]
then
     Left_Lights.sendCommand(ON)
end

rule "Switch ON Right Lights 2"
when
     Item Right_Lights changed [from OFF] [to ON]
then
    Right_Lights.sendCommand(ON)
end

rule "Switch ON Centre Lights"
when
     Item Centre_Lights changed [from OFF] [to ON]
then
     Centre_Lights.sendCommand(ON)
end

rule "Switch ON Other Lights"
when
     Item Other_Lights changed [from OFF] [to ON]
then
     Other_Lights.sendCommand(ON)
end
rule "Switch OFF Left Lights 1"
when
     Item Left_Lights changed [from ON] [to OFF]
then
     Left_Lights.sendCommand(OFF)
end

rule "Switch OFF Left Lights 2"
when
     Item Right_Lights changed [from ON] [to OFF]
then
     Right_Lights.sendCommand(OFF)
end

rule "Switch OFF Centre Lights"
when
    Item Centre_Lights changed [from ON] [to OFF]
then
     Centre_Lights.sendCommand(OFF)
end

rule "Switch OFF Other Lights"
when
     Item Other_Lights changed [from ON] [to OFF]
then
     Other_Lights.sendCommand(OFF)
end


Also, I have another doubt... My etc directory has 2 sub-directories openhab and openhab2. Is it normal?

Please use the code fences

No. Most likely you have installed in parallel OH1 & OH2
Get rid of the OH1 installation and use OH2 config files (for example: openhab.cfg is used in OH1)
For OH2, you should use /etc/openhab2/...) (e.g. /etc/openhab2/services/knx.cfg)

harshita · June 28, 2018, 8:43pm

Done
Sorry I am new to this

vzorglub · June 28, 2018, 10:30pm

To learn how to use the forum, send a message to @discobot with the subject “start new user” and “start new user” in the text box then follow the chat

vzorglub · June 28, 2018, 10:36pm

Then when you have finished do the same with “start advanced user”

Thank you

Hello everyone!
After installing KNX Binding in PaperUI, I do not see knx.cfg file in services directory.
Is it normal?

Dim · July 21, 2018, 1:00pm

the KNXv2 you mean…

harshita · July 21, 2018, 1:08pm

@Dim I have installed binding-knx - 2.3.0

Dim · July 21, 2018, 1:36pm

then, you won’t have a knx.cfg and you need to define your Bridge & Things

see here: KNX - Bindings | openHAB

@Dim Thanks!

Hi All,
I am almost at the end of my work but still have some doubts

My Items file

Switch demoSwitch1 "Left_Lights1" <Lights> {channel="knx:device:bridge:generic:controlSwitch1" }

My Things file
I have used textual configuration instead of Discovery method

    port=3671,
    serialPort="/dev/knx1",

    readingPause=50, 
    responseTimeout=10, 
    readRetriesLimit=3, 
    autoReconnectPeriod=1
   ] {
      Thing knx:device:bridge:generic {
       Type switch-control        : controlSwitch1        "Control Switch Left1"        [ ga="<1/1/51" ]

             }
       }

2018-07-26 09:33:19.958 [me.event.ThingUpdatedEvent] - Thing 'knx:serial:bridge' has been updated.
2018-07-26 09:33:19.961 [hingStatusInfoChangedEvent] - 'knx:serial:bridge' changed from UNKNOWN to OFFLINE (COMMUNICATION_ERROR): failed to open serial port /dev/knx1

This is the error I am getting.

KNXD works fine as I am able to read and write the bus using vbusmonitor1 and groupswrite

Can anyone help me on this?

Thanks in advance!

then your Bridge in OH2 KNX2 should be connecting to the knxd (via either tunnel or router type of IP connection)
The serial is being handled by knxd.

harshita · July 26, 2018, 12:24pm

I changed my things file as below and it works now

Bridge knx:ip:bridge [
    ipAddress="127.0.0.1",
    portNumber=3671,
    localIp="192.168.1.22",
    serialPort="/dev/ttyACM0", 
    type="TUNNEL",
    ignorelocalevents=true,
    readingPause=50, 
    responseTimeout=10, 
    readRetriesLimit=3, 
    autoReconnectPeriod=1,
    localSourceAddr="1.1.9"
   ] {
      Thing knx:device:bridge:generic {
       Type switch-control        : controlSwitch1        "Control Switch Left1"        [ ga="<0/0/51" ]
       Type switch-control        : controlSwitch2        "Control Switch Left2"        [ ga="<0/0/52" ]
       Type switch-control        : controlSwitch3        "Control Switch Left3"        [ ga="<0/0/53" ]
       Type switch-control        : controlSwitch4        "Control Switch Centre"        [ ga="<0/0/54" ]
       Type switch-control        : controlSwitch5        "Control Switch Others"        [ ga="<0/0/55" ]
             }
       }

harshita · July 26, 2018, 12:33pm

@Dim Oh Okay. Thanks!
