Knx switch works only one way

Setup, Configuration and Use Beginners
1

Hi all,

I have installed OH 5 on RaspberryPi and want be able to turn / off a knx light.

I did that before with older OH versions. At the moment I have the following issu: If I press the physical button and the switch on the monitor changes it’s state. That would mean the knx communication works somehow and the ga is correct. But the other direction does not work: If I change the state of the switch, the physical light does not turn on or off.

IP Interface configuration:

useNAT: false

ipAddress: 192.168.0.81

autoReconnectPeriod: 60

localIp: 192.168.0.176

localSourceAddr: 01.01.008

readingPause: 50

type: TUNNEL

Any ideas?

thanks

You need two GAs for the switch. One for the command to the switch and one for the return message from the device.

E.g. in a text file:

Thing device aktor1 "KNX Schaltaktor 1" [address="1.1.20", fetch=false, pingInterval=600, readInterval=0] {
        Type switch : Licht_EG_Stufen           "Licht EG Stufen"       [ ga="1/0/10+<1/1/10" ]
}

And the item should be configured this way:

Switch Licht_EG_Stufen   "Licht Stufen"       {channel="knx:device:bridge:aktor1:Licht_EG_Stufen"}

neither of the following work, always the same result (switch follows the light but there is no effect when turning the switch):

1/2/39

1/2/39+<1/2/39

1/2/39+<1/2/139

this addresses another knx light:

1/2/40

I cannot remember that I have used 2 addresses in the past (OH2-3).

Sorry youre correct. I found the second address in the knx documenation, thank you again!
