Rpi.rf problem

I’ve been struggling with the rpi.rf component for months.
When i set up hass on my rpi b+ and add the rpi.rf component it doesn’t send any codes.
Also a problem is that when i use the 433utils codesend, put it in a script and let hass execute the script. It says it has executed the script but nothing happens.

No errors in the logs.

Anyone can help me with this ?
