Telegramme aus Node-RED über BABTEC EIBPORT v3 funktionieren nicht

[TheMax74]

Yes, and i have here an enertex ip secure router/interface :-)

IP Interfaces mimics the TCP stack, but instead TCP, it uses UDP and this "mimic" is a bit trivial.

Modern IP Interfaces also support TCP. This is even required for Interfaces supporting KNnet/IP Secure.

TheMax74 Ok, think I will go for an IP-Router. Thank you for your Help.

Noch eine Frage in die Runde:
Hat jemand erfolgreich ohne Abbrüche Node Red am laufen mit einem BAB AppModule oder einem Eibport V3

[TheMax74]

Yes, because multicast is connectionless, so you don't have a real connection indication. Your device doesn't accept multicast connection. You need to sticky with IP address.
Sorry, i cannot help you anymore, because i don't know your interface. Go grab an IP Router and your problems will go away forever.
I use an eibmarkt IP router with success since 9 years, but every other IP Router will be OK. These devices make only one thing: ip routing. And they do it very well.

[andijegg]

So, I tried the Multicast Adresse. Connection is fine, but there comes no massages trough the connection.

[andijegg]

Sure, you are right. But I also use Sonos, Alex Garagedoor and HomeKit with my KNX Installation, the only things I miss now is Harmony an Roomba, that's the last 2 things I want to implement.

But you are right, an IP-Router would be the better choice...

[TheMax74]

Andijegg,
if you buy an IP Router, you'll find yourselft use node-red not only for Roomba and Harmony, but, like me, for your whole house, including homekit (if you have Apple), Sonos (if you have one, try my sonospollytts node), garage door and so on!

Be sure to buy an IP Router (costs more but it uses multicast), not an IP Interface.
IP Interfaces mimics the TCP stack, but instead TCP, it uses UDP and this "mimic" is a bit trivial.
Make also sure not to have DDOS protection, or UPD flood protection set on your switches/routers, because it can block KNX traffic as well.
Bye.

[andijegg]

Thank you I will try the Multicast-Addresse

Sure I know, I'm thinking about buying a Enertex IP-Router. But I only want to use node red for my Roomba and my Harmony remote, so if it works with the EibPort or the AppModule, it would save about 300 bugs... :-)

[TheMax74]

Hello
please try to use the multicast address instead of the ip address of your gateway
The multicast address is 224.0.23.12
Let me know.

As a note, it's always better to use a dedicated modern IP Router device, because these devices handles the connection a lot better.

Hi,

I think I've a similar problem like mikeh. I'm using an EibPort V3 and a Bad-Tec App Module as IP Gateway. I can get an connection to my KNX Bus via knx-ultimate and everything seems fine, but after a several minutes the connection get lost with the Error "knxUltimate: knxConnection error: E_CONNECTION_ID"

knx-ultimate Version is 1.1.14

The issu is the same, no matter I use the EibPort or the AppModule as IP Gateway/Router

I tried ACK on and off, that makes no difference.

[mikeh]

Hi together,
found the ACK Option in the KNX Ultimate Node and it worked. :-)
Thanks together for your support! :-)

Welche Versionen von:
nodered
node
nodejs
knxeasy
hast Du denn im Einsatz?

Hatte gerade das gleiche Problem und kenn evtl die Lösung

[TheMax74]

Hello mikeh
what’s the matter?
In the knx-ultimate config node, there is an option to fix the ACK for old ip gateways. Maybe you can select it and retry.
I really doesn’t have fully understood your issue, because my German speech is very limited.

Ich vermute, dass es am EibPort Router liegt. Kannst Du versuchsweise mal ein anderes IP-Gateway oder einen IP-Router verwenden? Der KNXultimate Knoten wurde von TheMax74 entwickelt. Vielleicht kann er was dazu sagen...

[mikeh]

Ja, das ist das Flag. Danke Dir! Schon mal einen Schritt nach vorne....auch wenn das dann wohl eher nicht der Grund ist, weshalb es nicht funktioniert. :-(

Gibt es irgend etwas was zu beachten ist bei Node-RED, damit die Telegramme passen?
