Listen on 0.0.0.0

[jason0x43]

Currently, the event server attempts to listen on the specific interface used to reach the hubitat hub. In at least some cases, it appears to detect the wrong interface (jason0x43/hacs-hubitat#120).

Consider having the server listen on 0.0.0.0.

I'm kind of wondering if this is what is causing me problems with my setup. I run HA in docker swarm, but not in Host mode for the network. I run it on an overlay network because it is in a swarm cluster. I want any container I run to be able to run on any of the cluster nodes.

What I have run into is I'm not getting the Hubitat events back into HA. I have the server URL and Port assigned in your integration so it isn't dynamic. That port is then exposed on the container with the docker definition. The problem I see is the traffic isn't being passed into the container correctly and I believe it is because it isn't listening on 0.0.0.0. Listed below is a netstat from inside the HA container. I have your integration set to port 8990 and you can see for this list it is on local address 172.18.0.12 and not 0.0.0.0

tcp 0 0 172.18.0.12:40000 0.0.0.0:* LISTEN 63/python3

tcp 0 0 172.18.0.12:8990 0.0.0.0:* LISTEN 63/python3

I can curl 8990 from inside the container, but I'm unable to curl that same port from the docker host even with the port mapped in the docker definition.

        "Ports": [
            {
                "Protocol": "tcp",
                "TargetPort": 8990,
                "PublishedPort": 8990,
                "PublishMode": "ingress"
            }
        ],

It looks like this is an older issue. Do you have any update on when this might be addressed?

I tested this today by adjusting the live code in the container and restarting HA from the gui.

Adjusted /usr/local/lib/python3.10/site-packages/hubitatmaker/hub.py line 446
address = '0.0.0.0' #s.getsockname()[0]

Once I restarted the HA service I was able to connect to that service port from the docker hosts. HA was also getting the status updates from my Hubitat hub and all was well.

As a bit of additional information on this. I have two overlay networks connected to the HA container. Unless there is a way to specify which one your service is listening on I think it is going to need to bind to 0.0.0.0. I have it this way because HA is behind my Traefik proxy and that lives on it's own overlay network. Second overlay is for HA and all its components.
