Hi all, I have been playing with settings of knx binding because of those issues (instability) and I came across one very bizarre behavior of the binding. when I inspect my knxd daemon config, it is clearly visible it is configured to listen to TCP port 6720. Also verified (with telnet), the machine…

@stamate_viorel @Udo_Hartmann I am running knxd on openwrt router, with usb interface connected to it. these are the defaults of the service /usr/lib/knxd_args --eibaddr=0.0.1 --client-addrs=0.0.2:10 --error=0 --listen-tcp=6720 --Name=KNX2 --Routing --Tunnelling --Discovery --Server=224.0.23.12 -…

depends on how you did your configuration (be aware that I only set the parameters which differ from default) what’s the output of systemctl status knxd.service

/usr/lib/knxd_args --error=0 --Name=KNX2 --Discovery --Tunnelling --Routing --Server --listen-local=/var/run/knxd --trace=0 -b usb:1:2:1 Network interfaces Local server The -i or --listen-tcp option tells knxd to accept client connections on a specific IP. The -u or --listen-local option tells knx…

yeah, it works so unstable, I guess it’s a bug in knx bundle, because the gateway (knxd) is working fine, listening to port, restart of knxd doesnt help, but restart of knx binding helps. all devices are on 100mbit wire, no wifi involved. so I “solved” it with a rule, like many people before me : r…

[image] vanja: I guess it’s a bug in knx bundle At least it’s no general bug, as knx here is working rock stable (since openHAB1.0 with only exceptions as openHAB2 came out and there was not knx2 binding yet)

Well, as I mentioned in my first post, its rock solid to most of the people, but there are cases of instability Knx2 mentioned here [image] KNX2 stopps working after a while (received disconnect response status 0x21) Bindings I solved it by programming a servi…

Did you try the knxd configuration that I proposed ? Also keep in mind tunnel is unicast and router is multicast maybe your networking is playing tricks on you ? It’s pretty easy to blame openhab sometimes but keep in mind the people that developed this spend a lot of time on it and Knox is one of …

the implementation of knxd on openwrt is strange, it has /etc/knxd.ini that it completely ignores and starts with whatever settings it wants. I will install knxd on raspbian where oh is running and run your proposed config from there. on debian i hope i will be able to edit knxd.ini or knxd.conf an…

You can also search Calimero knx that is what the binding is using. As a side note the knxd package hasn’t been maintained in openwrt for 4 years… But why don’t use the knx binding directly in openhab seeing you can move the USB ? https://www.openhab.org/addons/bindings/knx/#serial-gateway

I was thinking i need a real serial TPUART device to use the serial-gateway with the binding, but if it works with usb crap, i will most definitely give it a go, as I dont really need to route it through the network, the devices are next to each other. the version i’m running [OpenWrt Wiki] packag…
