I’ve put together a helpful little script that let me take full control of my Fire TV remote by remapping the keys. Before this, several buttons were just sitting useless, especially when I tried using them with Kodi. I gave Kodi’s key remapper addon a shot, but it didn\u2019t quite cut it. That\u2019s when I decided to roll up my sleeves and make something myself.<\/p>\n\n\n\n

This script has been a game changer for me. It might not be the textbook way to handle things, but guess what? It works great for what I need. If you\u2019ve been in the same boat, wanting all your remote’s keys to actually do something, you might want to give this a try.<\/p>\n\n\n\n

What\u2019s the Deal?<\/strong><\/h3>\n\n\n\n
<\/div>\n\n\n\n
    \n
  • Device Discovery<\/strong>: Automatically finds your remote by name. No manual setup required.<\/li>\n\n\n\n
  • Key Remapping<\/strong>: Converts unused or unsupported remote buttons into functional keys for your system.<\/li>\n\n\n\n
  • MQTT Integration:<\/strong> This allows some remote to integrate with MQTT to allow you to trigger other automations. <\/li>\n\n\n\n
  • Prevent Accidental Repeats<\/strong>: Adds a simple mechanism to stop the same button from sending multiple commands too quickly.<\/li>\n\n\n\n
  • Debug Insights<\/strong>: If you like to see what\u2019s happening under the hood, switch on the debug mode for detailed logs.<\/li>\n<\/ul>\n\n\n\n

                        \n
                      • Can’t Find the Remote?<\/strong> Make sure the remote’s name in the script matches its system name exactly. You can use the command below to check for your remote. <\/li>\n<\/ul>\n\n\n\n
                        <\/div>\n\n\n\n

                          \n
                        • Permissions Issues?<\/strong> You might need to run the script with more privileges or adjust the device file permissions.<\/li>\n\n\n\n
                        • Keys Not Behaving?<\/strong> Double-check your key_mapping<\/code> to make sure the commands are set up right.<\/li>\n<\/ul>\n\n\n\n
                          <\/div>\n\n\n\n
                          If you’d like to remap your keys, you can use the sudo evtest<\/code> command. Start by selecting the input device from the list presented. When you press a key, evtest<\/code> will output information similar to the example below. The value provided is your key code, which you’ll need to define in your script. For instance, in this example, c008d<\/code> is the key code. In the script, you should refer to it as x0c008d<\/code>.<\/p>\n\n\n\n

                          In my setup, I\u2019ve configured the MQTT buttons to interface with Home Assistant, allowing for seamless control of my TV and voice assistant. When I press the “Power” button, an MQTT message (power_pressed<\/code>) is sent, which is picked up Home Assistant then send a command to my Broadlink RM Pro to power my TV on or off. On the other hand, the “Voice” button is integrated with another script that enables voice control functionality. When this button is pressed, an MQTT message (voice_pressed<\/code>) triggers the script, allowing me to use voice commands to control various smart home devices or perform specific actions. To ensure accurate feedback, both buttons also send an idle<\/code> message after a brief period, indicating that they are no longer active. This setup not only simplifies the control of my TV and voice assistant but also ensures that every action is precisely tracked through MQTT messaging.<\/p>\n\n\n\n
                          That\u2019s about it! This setup has been rock solid for me, especially for my Kodi setup. If you\u2019re looking to get more out of your remote, why not give this a shot? Maybe it\u2019ll be just what you need. Cheers! \ud83d\ude80<\/p>\n\n\n\n
