Node-red and echo

I'm following this
Node-red is running as docker container in ubuntu as root.
Added echo hub node, added echo device node and link it to echo hub node, set a name.
then ask "Alexa, discover devices", but my echo dot can't find anything. did I miss some setting? where should I check for issue/error?


presumably you have set up the docker container networking correctly to allow discovery to happen ?

I'm not sure, :sweat_smile: could you please point me to some document or guide for that?

Google is your friend.

This helped me Amazon Echo Hub
and here

feeling dumb still not able to make it work. here is what I have done.

  • run node-red docker in ubuntu under root on port 1880: sudo docker run -itd -u root -p 1880:1880 xxxxx

  • run below to do port forwarding:
    sudo apt-get install iptables-persistent
    sudo iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
    sudo iptables -t nat -A PREROUTING -p udp --dport 80 -j REDIRECT --to-port 8080
    sudo iptables -t nat -L
    sudo sh -c "iptables-save > /etc/iptables.rules"

  • added echo hub and then connected to echo devices. echo hub node shows "connected"

  • asked "Alexa, discover devices" but didn't find anyone.
