I currently use a few Global Cache Flex units and my house which work perfectly with the UltraGCIR3 plugin but I needed a couple more and decided to roll my own. I have seen lots of examples of ESP8266 boards or bigger Arduino boards used, I currently use a couple UNO boards with switches attached built into our nightstands using the Arduino plugin but that is the extent of my "Maker" knowledge using those boards. Amazon delivered a couple NodeMCU boards Saturday afternoon but I had not ordered any other parts yet, into the junk box I went of coarse. I pulled an old Directv remote and a RGB light strip controller that had an IR receiver in it and stripped it out then pulled the IR diodes out of the remote.
I played around all day Sunday trying to figure this out with not much luck until I found this project https://github.com/mdhiggins/ESP8266-HTTP-IR-Blaster and I was up and running in 15 minutes.
I downloaded the IRController Arduino project file, made sure I had the correct libraries installed and just sent it straight to the NodeMCU over USB from the Arduino software. It was supposed to boot in AP mode but connected straight to my WIFI without any changes, I did already have projects running on it from my testing various things that had my SSID and password along with an IP address assigned to its MAC, so I assume that stayed somehow. Anyway once running I hit the address in Chrome and was sending IR signals to the NodeMCU with all the info displayed in a web page, click the code you just sent to it and it opens a page with examples of how to resend that code back out through the emitter. Now back to HS3 and I just created an event that sends a web request to fire the IR to the TV. I have never set up an IR system this easily and have used probably every remote setup you can name, for $8 and an emitter I took from an old Directv remote, I have a network IR server.
