+Recieve signals from a keyboard and use it as a remote control.
+
+This component allows to use a keyboard as remote control. It will
+fire ´keyboard_remote_command_received´ events witch can then be used
+in automation rules.
+
+The `evdev` package is used to interface with the keyboard and thus this
+is Linux only. It also means you can't use your normal keyboard for this,
+because `evdev` will block it.
+
+
+```yaml
+# Example configuration.yaml entry
+keyboard_remote:
+  device_descriptor: '/dev/input/by-id/foo'
+  key_value: 'key_up' # optional alternaive 'key_down' and 'key_hold'
+  # be carefull, 'key_hold' fires a lot of events
+```
+
+And an automation rule to bring breath live into it.
+
+```yaml
+automation:
+  alias: Keyboard All light on
+  trigger:
+    platform: event
+    event_type: keyboard_remote_command_received
+    event_data:
+      key_code: 107 # inspect log to obtain desired keycode
+  action:
+    service: light.turn_on
+    entity_id: light.all
+```
