 ## Sonoff RF Bridge 433
 
-Although the component supports training, it is recommended to train buttons through the eWeLink application.
+Component will create only one entity per RF Bridge - `remote.sonoff_1000abcdefg`. Entity RF Buttons or RF Sensors are not created!
 
-The component can both send RF signals and receive them, but only previously trained.
+You can receive signals from RF Buttons and RF Sensors through an event `sonoff.remote`. And send signals using the service `remote.send_command`.
+
+Although the component supports training, it is recommended to train RF Buttons through the eWeLink application.
 
 When a command is received, the event `sonoff.remote` is generated with a button number and response time (in UTC, sends the device).
 
 `command` - number of the button in the eWeLink application.
