Unable to setup emulated_roku

[chubby92 (Ron Fogel)]

So, I was able to understand my issue (I didnt add Roku device to harmony remote, just tried to send the Fwd button using one of my existing devices, how stupid?)
I am gonna write a quick guide on how to setup this roku with the harmony and home assistant so others will be able to do it smoothly.

please note that I was using home assistant installed on RASPBIAN STRETCH WITH DESKTOP

1. give write permissions to homeassistant folder (sudo chmod -R 777 /var/opt/homeassistant)
2. create folder custom_components inside the homeassistant folder
3. create file roku_emulated.py inside that folder from the above step
4. copy content of https://gitlab.com/mindig.marton/ha-emulated_roku/blob/master/components/emulated_roku.py to the roku_emulated.py
5. add the following configuration to the homeassistant’s configuration.yam (sudo nano /var/opt/homeassistant/configuration.yaml)

example:

emulated_roku:
    host_ip: 192.168.1.150 # should be set to Home Assistant's address
    advertise_ip: 10.0.0.10 # optional, defaults to host_ip if not specified
    upnp_bind_multicast: True # optional, defaults to True
    listen_ports:
    - 8060
    - 8061:8080 # optional format when using something like Docker - port:advertise_port

mine looks like that:

emulated_roku:
  host_ip: 192.168.1.100
  listen_ports:
    - 8060

6. reboot your raspberry pi (sudo reboot)
7. navigate to 192.168.1.100:8060 (the host_ip you just set in step 5 for the emulated roku (which is the homeassistant’s ip but with the roku’s port)
8. copy the serial number (the value between the serialNumber tags (<serialNumber>5sEE3ioBPJU2m3ZR2QBHDb</serialNumber>)
9. add the following automation script to your automations.yaml (sudo nano /var/opt/homeassistant/automations.yaml)

example:

- id: Test Roku Automation
  alias: test_roku_automation
  trigger:
  - platform: event
    event_type: roku_command
    event_data:
      roku_usn: 5sEE3ioBPJU2m3ZR2QBHDb
      type: keypress
      key: Info
  action:
  - service: media_player.volume_up
    entity_id: media_player.amplifier

pay attention the the following stuff:

• the roku_usn’s value should be the serial number from step 8.
• you may find the service name and entity id in your homeassistant’s web ui under developer tools
• a list of harmony keys https://sdkdocs.roku.com/display/sdkdoc/External+Control+API#ExternalControlAPI-KeypressKeyValues

10. reboot your raspberry pi (sudo reboot)
11. add a new device to your harmony remote control
12. choose Roku as the brand and 1 and model (you can also find it in the discoverable devices)
13. finish to add the Roku device and thats it you are good to go!
14. press on the button that you configured in step 9 (Info button) and watch the magic
