Instructable - NodeMCU ESP8266 Based Switch Board with Raw TCP/IP and Mqtt Using Omega
I just found this new instructable which uses the Onion Omega: http://www.instructables.com/id/NodeMCU-ESP8266-Based-Switch-Board-with-Raw-TCPIP-/
While the ESP8266 based boards are interesting, it is not an Omega. It does run a tiny linux and tcp/ip stack somewhat like the omega, they are different devices.
@Chris-Ward.. true... but this project uses the omega to control the esp8266. The title may not mention the Omega but the project uses it to run the MQTT system
@Nayan Sorry, you are right. I read a little ways down, but not all the way. I didn't see that they were using the Omega as a hub with MQTT.
