Hue emulation, should I be able to add OH as a new bridge in the Hue app?

I’ve installed the hue emulation binding and added the iptables rules to forward port 8080 to port 80 as per the documentation. The official Hue app can’t see the new emulated bridge but the Hue Essentials app on Android can see it and add it as a new bridge. However, I can’t do anything with the OH Hue bridge due to errors in the Hue Essentials app:

Unexpected response from bridge. Please try again later

End of input

The documentation for the hue emulation binding concentrates mainly on allowing devices to be discovered by Alexas and Google Homes to allow voice control. Is adding the emulated bridge to the Hue app expected to work or should I only expect discovery of emulated devices on my Google Home devices?

I hadn’t installed nginx and placed the following config in /etc/nginx/conf.d/openhabhue:

server {
    listen 80;

location /api {
      proxy_pass http://<ip address of OH server>:8080/api/;

location / {
    proxy_pass                              http://<ip address of OH server>:8080/;
    proxy_set_header Host                   $http_host;
    proxy_set_header X-Real-IP              $remote_addr;
    proxy_set_header X-Forwarded-For        $proxy_add_x_forwarded_for;
    proxy_set_header X-Forwarded-Proto      $scheme;

Where <ip address of OH server> in my case is

I could then add the OH Hue bridge in Hue Essentials, I can’t seem to add it in the official Hue app though.

I wont get too involved in the Hue emulation discussion since I neither use it nor know its details. However in general your observations do not surprise me. Philips / Signify has done a huge amount of work in their eco system in the last year or so. Specifically (to name a few) they have added API v2, added Matter support, added security devices, and many other new devices. They have deprecated API v1 but they have not (yet) deleted it. However none of the above mentioned new features are back ported to API v1. Specifically the Hue app uses API v2. Whereas I guess that Hue emulation probably uses API v1…
