I am working on getting my Matrix Creator to operate my smart devices using Alexa. I have successfully installed Alexa on my Matrix Creator, but I have been unable to connect any smart devices to it.
There is a tutorial for enabling the GPIO inputs / outputs of the RPi as smart devices (http://www.instructables.com/id/Control-Raspberry-Pi-GPIO-Using-Amazon-Echo-Fauxmo/) as well as several tutorials for creating a smart device using a ESP8266 (http://tinkerman.cat/emulate-wemo-device-esp8266/). I have tried both, but neither is able to be discovered by Alexa.
I have been breaking my head over this a couple weeks now, with no progress whatsoever. Everything seems to be working fine, nonetheless Alexa reports there are no smart devices.
