The setting exists but will remain undocumented. If you know enough to find it you can use it, that is the thinking at least.
Got a bit further, but discovery still failed:
Ahhhh, I think I see what is going on now

It seems like it is asking a bunch of devices on my network (looking for alexa devices) on port 80, but it seems that would be redirected to 6000 because of our changes, but should be broadcasting out to the network at 80 because it got re-redirected right? Not sure how that setup.xml would come back to NR though.
change the 6000 setting in the node, but keep the environment variable. maybe that will fix it.
Interesting, those logs coincide directly with me asking her to discover devices. Not sure if that helps clear up anything.
Tried it, didnāt crash NR which is good, but did not seem to do much to fix it.
That didnāt change those messages to use port 80 instead of 6000?
No, but I will try a full redeploy and try again.
Edit: Nope, but it did seem to find my 4 echo dots properly:

I wonder if that setting is only relevant for the webserver option:
This node is setting up the controller node for alexa interaction. It starts a SSDP Service on Port 1900/udp and is also able to start a seperate webserver on the configured port.
But it is also possible to use node-red as webserver and donot start a second webserver.
Be aware that alexa requires a response server running on port 80!
Yeah, unfortunately looking at the code it seems to be using the ALEXA_PORT setting for both that outgoing call as well as the incoming callsā¦ not ideal.
Thereās a way to make it possible to listen on port 80 directly without running as root though. Hang on, need to check how I have that controlled.
EDIT: Just checked, I have already set port 80 to be the first unprivileged port on CORE. Try removing the portmap and set ALEX_PORT=80
EDIT2: Check what you get as output from:
sudo sysctl net.ipv4.ip_unprivileged_port_start
Did it work with āALEXA_PORT=80ā?
Sorry, broke for dinner:

oh-la@Collective-Core:~$ sudo sysctl net.ipv4.ip_unprivileged_port_start
net.ipv4.ip_unprivileged_port_start = 80
Edit: Added at 80:80 port map with both 0.0.0.0 and coreIP and no luck with either.
When using host networking, skip portmap for all ports. Set āPORT_MAP=()ā.
Also set environment variable ALEXA_IP=COREIP
Though not sure thatāll work as intended
Trying this now:
---- CONFIG OVERRIDES START ----
REDACTED
ENV_MAP+=("ALEXA_PORT=80") # Used port mapping instead
ENV_MAP+=("NODE_RED_ENABLE_SAFE_MODE=true")
No dice, same error as usual.
ENV_MAP+=("ALEXA_IP=CORE_IP_HERE")
Did that resolve it?
EDIT: This is the part of the code mentioning that environment variable: node-red-contrib-alexa-home/alexa-hub.js at 3c1c8e8b117b9bb10549a3e33ee55f0bdc29ced0 Ā· mabunixda/node-red-contrib-alexa-home (github.com)

Thank you so much Markus, I think you cracked it!! Discovery worked and NR to alexa as well as alexa to NR works
Now, is it worth investigating if the REDACTED option is truly necessary?
Probably not since the discovery being used wonāt forward without it.
Nice itās working
Is this Alexa integration complete? Ie are there any features missing the other one provides?
Not really, all this does is emulate a Philips Hue hub, so it is basically just lights as virtual devices, which you can do a lot with, but it isnāt native (for instance I use a dimmer as a mode controller with each light level another mode)
I think this one is a bit more complete, but I can get back to you on that.
Edit: Nevermind, that node is not set up the exact same and is outputting a similar error:
āError: listen EADDRINUSE: address already in use :::80ā
I see, at least itās local
Ok, and I also see itās very old and not maintained.
If you find something more complete Iām sure others would also like to hear about it. From my understanding you canāt get complete support and stay local. You either have to use a separate cloud service, like that other paid for one, or use portforwarding.
Yeah I was thinking about that, it might be local, but alexa NLP is computed in AWS, so what use is it if you canāt even talk to her to turn this stuff on. Also I assume the app does not work without internet either.
Less roundtrip time and no additional service or portforwarding involvedā¦
