Change of KNX IP Router

Platform information:

Hardware: Raspberry Pi 3
OS: _Raspbian Linux raspberrypi 4.19.75-v7l+
Java Runtime Environment:openjdk version "17.0.7" 2023-04-18

Hello,

I have replaced my IP Router (MDT SCN-IP000.03) by the same type because the old one didn’t work anymore.
After some struggle it is workin in the ETS an also KNX Values are shown in the log viewer:

2024-03-06 21:35:10.484 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item ‘UG_Verteiler_Heizungsaktor_8fach_1_UG_Hauswirtschaft_Stellwert’ changed from 0.50588235294117645 to 0.4901960784313726

2024-03-06 21:35:22.355 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item ‘SMA_Energy_Meter_Bezogene_Leistung’ changed from 560.3 to 619.7

2024-03-06 21:35:53.352 [INFO ] [openhab.event.ItemStateChangedEvent ] - Item ‘SMA_Energy_Meter_Bezogene_Leistung’ changed from 619.7 to 619.3

The Bridge (IP Router) is shown as online.
All the KNX Devices Things stay offline.

2024-03-06 21:25:40.993 [INFO ] [ab.event.ThingStatusInfoChangedEvent] - Thing ‘knx:device:1dd5466f53:EG_Kinderzimmer_Glastaster’ changed from UNKNOWN to OFFLINE

Any idea what can be wrong? There was no change in the parameters of the things at all.

Examploe of one thing:

UID: knx:device:1dd5466f53:EG_Kinderzimmer_Glastaster
label: EG_Kinderzimmer_Glastaster
thingTypeUID: knx:device
configuration:
pingInterval: 600
address: 1.1.28
readInterval: 0
fetch: false
bridgeUID: knx:ip:1dd5466f53
location: EG_Kinderzimmer
channels:

  • id: EG_Kind_Raumtepmeratur
    channelTypeUID: knx:number
    label: EG_Kind_Raumtepmeratur
    description: “”
    configuration:
    ga: 9.001:2/3/6

And the gateway:

UID: knx:ip:1dd5466f53
label: KNX/IP Gateway
thingTypeUID: knx:ip
configuration:
useNAT: false
readRetriesLimit: 3
ipAddress: 192.168.178.93
autoReconnectPeriod: 60
localIp: 192.168.178.20
localSourceAddr: 1.1.0
readingPause: 50
type: TUNNEL
portNumber: 3671
responseTimeout: 10
location: Technikraum_Verteilerschrank

Any idea? Looking forward for your feedback!

Don’t set the localSourceAddr, leave it empty or set it to 0.0.0

solved. Thank you so much Udo, I was searching for a solution for days…
