I currently have the following setup (both in the same subnet @ home)
raspberry pi zero with diyhue (automatic install) with ip 205, i can access the webbrowser of this ip and can link with my app. This raspberry pi zero has also nmap installed.
Next to this i have one nodemcu with WS2812 light (ip 222) that i also can connect with the webbrowser (port 80). In dit minimal webbrowser i can change the color of the light, on/off, etc. (https://github.com/mariusmotea/diyHue/blob/676aff78f54dc9e58b3f28f94c05b13d63e8cf28/Lights/Arduino/WS2812BHueStrip/WS2812BHueStrip.ino)
Both are checked with a desktop computer with ip 223.
On the diyhue bridge (205) i can ping/nmap the ws2812 light on ip 222.
pi@raspberrypi:~/diyHue/BridgeEmulator $ nmap -F 192.168.178.222
Starting Nmap 7.70 ( https://nmap.org ) at 2020-03-04 14:06 GMT

However, my apps on my iphone/android (hue essentials and others) and pc (lamp-finder) don’t recognize my lamp but i can connect to my bridge.
