Using Emulated Hue with regular Hue for home control buttons on Harmony

I’m hoping someone can help me out here because I’ve searched high and low over the internet the past few days and am starting to lose my mind.

I have a physical Philips Hue bridge and lights, the Logitech Harmony Companion and I want to assign the home control buttons on the remote to scenes, which I know can’t be done without intervention.

This is the remote I have, and these are the buttons I want to program with light scenes.

I’ve been playing around with Emulated Hue, assuming that’s the route to go. But now I’m not so sure.

The scenes I want to control were created within the iOS Home app (not sure if that matters and if I need to recreate them elsewhere) - one is ‘TV Mode’ which basically dims my three Philips bulbs in the living room; the second is ‘Normal Mode’ which turns them back up to 100% brightness.

What is the simplest way to do this, please?

Below is a section of my configuration.yaml for Emulated Hue:

host_ip: !secret ha_ip_address
listen_port: 8300
advertise_ip: !secret ha_ip_address
advertise_port: 8300
upnp_bind_multicast: true
  - script
  - scene
expose_by_default: false
  - light
  - switch
  - input_boolean
  - group
    name: "HH"
    hidden: false

And then I have another YAML - light_group.yaml - as below:

- platform: template
      friendly_name: "HH"

When I navigate to http://myIP:8300/api/pi/lights I see the following:

  "1": {
    "state": {
      "on": false, 
      "reachable": true, 
      "mode": "homeautomation", 
      "bri": 1
    "name": "HH", 
    "uniqueid": "00:eb:5b:f5:28:00:21:f3-2a", 
    "manufacturername": "Home Assistant", 
    "swversion": "123", 
    "type": "Dimmable light", 
    "modelid": "HASS123"

And when I navigate to http://myIP:8300/description.xml, I see the following:

<root xmlns="urn:schemas-upnp-org:device-1-0">
    <friendlyName>Home Assistant Bridge (REDACTED)</friendlyName>
    <manufacturer>Royal Philips Electronics</manufacturer>
    <modelDescription>Philips hue Personal Wireless Lighting</modelDescription>
    <modelName>Philips hue bridge 2015</modelName>

So it would appear everything is setup as it should be, although I’m not sure I need to do it this way, i.e. creation of two lights via the light protocol, creation of a group, and then the entities within the Emulated Hue declaration - seems overkill, but I don’t know.

Within the Home app, I can see the following:

All looks good so far.

And I can even get as far as opening the Harmony iOS app and going to Devices > Add Device > Home Control and Philips Hue does appear in there. It will try to connect and then I get the following screen:

But then it goes back to the Add Device page having not added the device. I then have to re-sync the Harmony app before it will appear again, and then the same thing happens again and again.

So… that is as far as I can get! Any help and support would be massively, massively appreciated. If I can program those home control buttons I’ll be a happy guy!
