Synology integration returns error when adding DSM with VLAN network config

[agios]

The problem

When trying to add a Synology DSM with a multiple VLAN network configuration the following error eccurs:

The problem seems to be that when you have a custom network setup on Synolgy, then the SYNO.DSM.Network call returns an empty interfaces list:

{
  "data": {
    "dns": [
      "192.168.98.1"
    ],
    "gateway": "192.168.98.1",
    "hostname": "nvr",
    "interfaces": [],
    "workgroup": "WORKGROUP"
  },
  "success": true
}

Confirming this behavior...since days trying to add synology rackstation without success...

in syno log i see a successfull login... in HA logs also ... almost... but thats it...

have the same "missing data error" ... at the end the integration dont integrate :-/

same empty interface list in API query...like the thread creator...any hints regarding syno api?

[mib1185]

unfortunately, this is a bug in the DSM itself. we need the list of interfaces - especial their mac addresses - to identify and ignore already configured nas in HA during automatic discovery (ssdp)
