How can I connect to KNX Virtual? #9

Closed mortiy closed 3 years ago

mortiy commented 3 years ago

I'm trying to connect to KNX Virtual setup via: knxClient.startDiscovery("127.0.0.1");, but getting this error:

Error: send ENETUNREACH 224.0.23.12:3671
    at doSend (dgram.js:683:16)
    at defaultTriggerAsyncIdScope (internal/async_hooks.js:351:12)
    at afterDns (dgram.js:629:5)
    at processTicksAndRejections (internal/process/task_queues.js:85:21) {
  errno: 'ENETUNREACH',
  code: 'ENETUNREACH',
  syscall: 'send',
  address: '224.0.23.12',
  port: 3671
}

Anyone was lucky enough to make this work?

Why did you pick the loopback IP ? Seems like we can't send multicast message on the loopback. Can you try with a physical interface ?

Yes, physical interface IP helped. Thanks.

Why did you pick the loopback IP ? I was just following the IP address from here. image

OK. Good to know. Just in case, as you know the IP and port, you can skip the discovery part and just open the tunnel immediately.

BTW. Didn't know there was a KNX Virtual App. I did request it and I'm going to start testing. Also, I developed this KNX-IP lib because I use it in a bigger project that includes a server to control, monitor, ... entire house. All in Typescript. And I use it for my own house since last year. It controls all the blinds, records all the sensor info and graphs them, ... I will publish a free version of the backend server in the near future with possibility to buy the GUI
