 The `rfxtrx` platform support lights that communicate in the frequency range of 433.92 MHz.
 
+Make sure you trigger a dimming command to get switches detected as lights otherwise, they will show up as switches.
+
+#### Convert switch event to dimming event
+
+To convert a standard switch to a light, use the [Light Switch](integrations/light.switch/) component.
+
+To convert a switch to a dimmable light, make sure the event contain a dimming command. You can usually convert a command by changing one byte.

 ### Switches
 
 The `rfxtrx` platform support switches that communicate in the frequency range of 433.92 MHz.
 
-#### Generate codes
-
-If you need to generate codes for devices, you can use a template (useful for example for COCO switches).

-0b11000{{ range(100,700) | random | int }}bc0cfe0{{ range(0,10) | random | int }}020f70
