UPnP Interface with Draytek Router Broken

Third party integrations
1

Hello all,

I have a Draytek 2860Ln Router which HA happily found.
However the interface doesn’t work, digging in the logs found the cause…

UPnP/IGD (Internet Gateway Device) has a standard protocol which (as described in http://upnp.org/specs/gw/UPnP-gw-WANCommonInterfaceConfig-v1-Service.pdf ). It specifies an ‘action’ to get the number of packets received, called GetTotalPacketsReceived, page 16 of that document. The action has one OUT-argument: NewTotalPacketsReceived.

The 2860Ln, however, reports it as NewTotalPacketReceived, it misses the ‘s’ off Packets. This causes the interface to fail.

I’ve reported it to Draytek but I can’t imagine they’ll ever fix it.

Is there any way I can tweak my HA instance to expect the incorrect spelling?

It’s in the async_upnp_client module at line 114 (currently) of igd.py (github link)

If you can find and edit that file on your system, it should work after a restart.

Thanks for the quick response Troon.

I made the edit in igd.py and changed:

total_packets_received: int = result["NewTotalPacketsReceived"]

to be

total_packets_received: int = result["NewTotalPacketReceived"]

After restart still getting the error:

@paulrickwood - did you get anywhere with this one? Keen to resolve the same for myself.

No unfortunately not.
Away for Christmas but will have another look when I get back.
