Hello I want “dumb” lights to work within scenes in Philips Hue. My thinking was that I wire in a smart light controller eg
Something like NUE ZigBee 3.0 Smart Light Controller.
The issue is that although I can get them to switch on/off I can’t get them to do the same within a scene which includes smart bulbs. The one I mentioned says it does work within scene but I have tried a number of different ones now and keep hitting the same issues. Has anyone been able to achieve this?
I’m sure that’s very frustrating. 
This forum is for people who are using the Samsung SmartThings ™ Home Automation platform. So all of the questions and answers are assumed to be in that context. It is a very busy community, so it often comes up near the top on general home automation searches, but it is not a general forum.
Many of the Nue zigbee products work just fine in SmartThings scenes (created in the SmartThings app, not the Hue app), and most people in this forum will be using the SmartThings app, so I’m not sure you’re going to get much help here. 
I suggest you ask your question in the Reddit Home Automation subforum. They cover all platforms. Or you could try asking in a Hue forum.
Good luck!
