Hi!

Make sure you map the keycodes from the remote to the corresponding button. They may not be the same as your keyboard:

If you’re using the CLI + SDK add

"keys": {
      "8": "Last",
      "13": "Enter",
      "27": "Exit",
      "33": "PageUp",
      "34": "PageDown",
      "37": "Left",
      "38": "Up",
      "39": "Right",
      "40": "Down",
      "68": "Debug",
      "71": "Guide",
      "72": "Hint",
      "73": "Info",
      "76": "Last",
      "77": "Menu",
      "78": "Next",
      "80": "Prev",
      "84": "TextBanner",
      "86": "VoiceGuidance",
      "179": "PlayPause",
      "83": "Star",
      "227": "Rewind",
      "228": "FastForward",
      "219": "Rewind",
      "221": "FastForward",
      "403": "ColorA",
      "404": "ColorB",
      "405": "ColorC",
      "406": "ColorD"
    },

to settings.json under appSettings. You may need to change the keys to work with the device. Might require some console.logging to find out what the corresponding ascii key is that the remote is providing.
