My ESP8266 is NOT discovered by the Alexa App nor the Philips HUE App

[alphastint]

Hello,

I have an esp8266 module with WiFi enabled. I would like to connect the module to my Alexa App or the Philips HUE app on my phone. Alexa only states that no device is discovered, and does not even try to connect to the device.
Philips HUE on the other hand has the option to discover a device by IP address. If I specify the esp8266 address in the app, then the app tries to visit the

[FAUXMO] URL: /api/config

which does not exist on the device, then it downloads the

http://192.168.217.73:80/description.xml

a few times. The local ip being the esp8266 module. Finally the response is No Hue Bridge found.

Is this a new api call that is not implemented in the device, are there other issues?

Thanks for any help.

mine works fine, only turns on the esp-01's blue LED though...

i want to pass the dimness of the light to a servo soo thats my only hangup. (for a windows blinds project)

BUT below is the code i use and when i add it to alexa through the app via these steps. (current phone app)

hit the + top right, add device, then scroll down to the bottom of the list select 'other', tap the WiFi button on the next screen and finally select 'discover devices'

change the names here in the code (i named mine smeg)
fauxmo.addDevice("PUT A NAME HERE TO SEE IN ALEXA"); // this part always seen on alexa app for and after discovery

and here
request->send(200, "text/plain", "PUT-A-Name-Here is Online and waiting for alexa"); // this part never work out the serial port (probably because im using a esp-01s)
