Alexa can't find more new hue devices

  • Platform information:
    • Hardware: X64 / RAM 4Gb / 64 Gb eMMC
    • OS: Ubuntu 20.04
    • Java Runtime Environment: Zulu11.54+25-CA (build
    • openHAB version: 3.4.2
      The Hue emulation works with my Alexa devices but starting from today it is impossible to detect new devices.
  • Nginix is working and configured according this file:
server {
  listen 80;
  location / {
    proxy_pass                              http://localhost: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;

  location /api {
    proxy_pass http://localhost:8080/api/;
  • Here is the iptables configuration (iptables -S):
  • The self test is ok (http://MY_IP_ADDRESS/api/status).
  • Both http://MY_IP_ADDRESS:8080/description.xml and http://MY_IP_ADDRESS/description.xml show the description file.
  • Both curl http://MY_IP_ADDRESS:8080/api and curl http://MY_IP_ADDRESS:8080/api/ give:
    [{“error”:{“address”:“/”,“description”:“Not Authorized”,“type”:4}}]
  • When I start the pairing the log shows:
023-03-19 21:55:25.805 [INFO ] [ueemulation.internal.upnp.UpnpServer] - Hue Emulation UPNP server started on
2023-03-19 21:57:13.619 [INFO ] [io.hueemulation.internal.ConfigStore] - Hue Emulation pairing enabled for 180s
2023-03-19 22:00:13.621 [INFO ] [io.hueemulation.internal.ConfigStore] - Hue Emulation disable pairing
  • The the item to be recognized is a dmmer tagged with Lighting label.

To start the detection, I set the hue emulation in this way:

  • Device Pairing: on
  • Pairing: Add Unknown User-Keys: on
  • Optional Discovery Web Port: 8080

With these settings, the other five items were correctly detected by Alexa, but now I’m unable to understand where the problem is.
I will be grateful to anyone who can give me some suggestion to fix this issue.
Thank you


This issue should be fixed in OH 4.0.

Dear Mike,
you are right: the ID of the the new exposed item is 479.
Thanks a lot!
