How to run emulated hue from a docker container?

Configuration
#1

I am running Home Assistant inside a docker container (not using host mode) and I am unable to get the hue emulation to work. My current docker compose config for Home Assistant:

homeassistant:
    container_name: homeassistant
    restart: unless-stopped
    image: homeassistant/raspberrypi4-homeassistant
    volumes:
      - ${DATADIR}/homeassistant/config:/config
      - /etc/localtime:/etc/localtime:ro
      - /dev/serial/by-id/:/dev/serial/by-id/
    ports:
      - 8123:8123
      - 80:80
    cap_add:
      - NET_BIND_SERVICE
    environment:
      - PUID=${PUID}
      - PGID=${PGID}
      - TZ=${TZ}

and the hue config:

# hue emulation
emulated_hue:
  listen_port: 80
  host_ip: 192.168.2.4 # which is the IP of the pi running docker
  expose_by_default: true
  exposed_domains:
    - light

This is resulting in the following error at startup:

Error during setup of component emulated_hue
Traceback (most recent call last):
File “/usr/src/homeassistant/homeassistant/setup.py”, line 215, in _async_setup_component
result = await task
File “/usr/src/homeassistant/homeassistant/components/emulated_hue/init.py”, line 131, in async_setup
listen = create_upnp_datagram_endpoint(
File “/usr/src/homeassistant/homeassistant/components/emulated_hue/upnp.py”, line 73, in create_upnp_datagram_endpoint
ssdp_socket.setsockopt(
OSError: [Errno 99] Address not available

Does anyone know what is causing this or how to fix it? Do I need to also add advertise_ip to the config or add some UPNP ports?

try

  host_ip: 127.0.0.1
  advertise_ip: 192.168.2.4
#3

Thanks, that seems to help in a way. It starts without an error now. Nothing is found by Alexa though and http://192.168.2.4/description.xml can not be found in the browser. Current config

emulated_hue:
  listen_port: 80
  host_ip: 127.0.0.1
  advertise_ip: 192.168.2.4
  expose_by_default: true
  exposed_domains:
    - light

Do I need to update any port settings too?

#4

It may be that inside the container there are still port/permission issues, try listening on 8300 and changing the docker forwarding from 80 to 8300

#5

Very good idea, I also tried that. Not sure what I am doing wrong though. Added

ports:
      - 8123:8123
      - 80:8300

and used the settings above with listen_port: 8300 but I am still not able to see the description.xml file. Is there a way to enable debug logs just for the emulation? Would like to know if there is an error there or in my general port/ip setup

#6

Did you ever get this working? I’m looking into this myself and running into similar issues. Just looking for clues.

#7

No unfortunately not. I had to switch to host mode

#8

Would you be willing to provide a simple HOW TO as I cannot even verify that emulated_hue integration has been loaded.

In what sense? did you somehow manage to connect the home assistant devices on alexa? if so, could you show me the way?

What worked for me was setting a static ip for home-assistant in docker-compose.yml and using that same ip in the emulated hue config.

192.168.2.4 = docker host ip
192.168.10.6 = static ip for docker container

Example hue config:

  host_ip: 192.168.10.6 
  listen_port: 80
  advertise_ip: 192.168.2.4
  upnp_bind_multicast: false
  expose_by_default: false
  entities:
    light.living_room:
      name: Emulated Living Room Lamp
      hidden: false

Example docker-compose.yml

    image:  homeassistant/home-assistant:latest
    container_name: homeassistant
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Etc/UTC
    volumes:
      - /home/user/docker/homeassistant:/config
      - /etc/localtime:/etc/localtime:ro
    ports:
      - 8123:8123 #access home assistant
      - 1900:1900/udp #SSDP Discovery and uPNP
      - 5353:5353/udp #mDNS
      - 5683:5683/udp #Shelly
      - 80:80 #Emulated Hue
    restart: unless-stopped
