    Yet another WiFi-IR bridge that has not yet been covered in the LIST.

    Product image (taken from the marketplace):

    A couple of more pics of the inside that I took:

    Only a few wires are needed to be soldered on:

    We can use the provided USB cable to power the device during flashing/configuration.
    Flashing is done the usual way.

    Here is the configuration the is working for me:
    
      "pins": {
        "6": "Btn;0",
        "7": "IRRecv;2",
        "8": "WifiLED;1",
        "26": "IRSend;3"
      }
    


    The Autoexec.bat file is very simple:

    
    startDriver IR
    


    Other config to taste - and ready!

    cool. after pairing the storage areas in that bin contains

    Code: Text
    Log in, to see the code


    the OBK template for your device matches at least 4 in the device list for other IR blaster-type devices. Converting to OBK with that firmware is possible with Cloudcutter

    Thanks for the input! I haven't used Cloudcutter before, so I don't know anything about it. Is it something you can convert to OBK with without opening the device?
