Emulated Hue Bridge Not found gotcha

Maybe obvious to some, but not to me. I had a lot of trouble getting Alexa to see my Emulated Hue Bridge. I had previously hardwired my Pi running HASS.io and deleted my WiFi settings.
Reenabling WIFI solved the problem.
Also Node Red Amazon Local required the WiFi to be active during discovery. After discovery it works fine without WiFi.
