+# JSON IR remote
+
+## Purpose 
+
+The JSON IR remote allows users to customize IR remote behavior without writing custom code and compiling. 
+It also enables using any remote that is compatible with your IR receiver. Using the JSON IR remote, you can
+map buttons from any remote to any HTTP request API or JSON API command.  
+
+## Usage
+
+* Upload the IR config file, named _ir.json_ to your board using the [ip address]/edit url. Pick from one of the included files or create your own.
+* On the config > LED settings page, set the correct IR pin.
+* On the config > Sync Interfaces page, select "JSON Remote" as the Infrared remote.
+
+## Modification
+
+* See if there is a json file with the same number of buttons as your remote. Many remotes will have the same internals and emit the same codes but have different labels.
+* In the ir.json file, each key will be the hex encoded IR code.
+* The "cmd" property will be the HTTP Request API or JSON API to execute when that button is pressed.
+* A limited number of c functions are supported (!incBrightness, !decBrightness, !presetFallback)
+* When using !presetFallback, include properties PL (preset to load), FX (effect to fall back to) and FP (palette to fall back to)
+* If the command is _repeatable_ and does not contain the "~" character, add a "rpt": true property.
+* Other properties are ignored, but having a label property may help when editing.
+
+
+Sample:
+{
+  "0xFF629D": {"cmd": "T=2", "rpt": true, "label": "Toggle on/off"},  // HTTP command
+  "0xFF9867": {"cmd": "A=~16", "label": "Inc brightness"},            // HTTP command with incrementing          
+  "0xFF38C7": {"cmd": {"bri": 10}, "label": "Dim to 10"},             // JSON command 
+  "0xFF22DD": {"cmd": "!presetFallback", "PL": 1, "FX": 16, "FP": 6,  
+               "label": "Preset 1 or fallback to Saw - Party"},       // c function
+}
