Hello everyone 
2nd Edit: Solved my own issue - solution below as it may help someone else.
Original issue:
I’m having some trouble getting emulated_hue running on the Raspberry Pi3.
Some background info:
I installed hass.io on the Pi3 - it found my two limitless LED’s - bedroom and bathroom after I added this conf yaml:
Lights
light:
- platform: limitlessled
bridges:- host: 192.168.1.32
port: 8899
version: 2
groups:- number: 1
name: Bedroom
type: rgbw - number: 2
name: Bathroom
type: rgbw
- number: 1
- host: 192.168.1.32
This allows full RBGW control from my web UI.
First win!
Today I opened up my google home then got it all setup, then tried to enabled Emulated_hue but no luck on getting this to run.
the code in the config yaml
emulated_hue:
listen_port: 80
I have changed this many times and tried all different config including adding type: googlehome etc without any change in status.
(Port 80)
When I open: http://192.168.1.33/api/pi/lights
500 Internal Server Error
Server got itself in trouble
When I open: http://192.168.1.33/description.xml
I get an XML with details as expected.

I have spent hours on google and going through all the 500 errors on these forums and nothing has worked. I saw a comment on a hass forum post saying to create: emulated_hue_ids.json but no idea what goes into that file? Didn’t help too much.
Log from hass:
The following errors have been logged this session:
2017-08-05 11:29:33 WARNING (MainThread) [homeassistant.components.emulated_hue] Failed to open emulated_hue_ids.json: Expecting value: line 1 column 1 (char 0)
thanks for any help! 
Edit:
I THINK I FIXED IT:
I added some generic text from the GIT into the json file
it auto updated to the correct led config!
Solution:
Google Home/Pi/Port 80: The command on hassio site for pi user to access port 80 does not work (hassbian)
port 80 for pi please use:
sudo setcap ‘cap_net_bind_service=+ep’ /usr/bin/python3.4
to Enable Hue please use commands below: navigate to the /.homeautomation folder (raspberry pi terminal).
cd /home/homeautomation/.homeautomation
sudo mk emulated_hue_ids.json
sudo nano emulated_hue_ids.json
paste in this text - HASS will change it to match your config!
You likely don’t need a reboot but I did.
