433MHz module not working with RPI4

[pijoe56]

Hi,
I have been using these modules with my Rasperry Pi3 and Zero and it has always worked perfectly, now I have tried it with the Raspberry Pi4 and despite the fact that the codes are sent it does not work. can someone help me, thanks.

[code]RF_COMMAND='/home/pi/433Utils/RPi_utils/codesend'
remote2off = '123456'
subprocess.call([RF_COMMAND, remote2off]) # remote2 switch off
...[/code]

I have a new 433MHz module and I can't get it to work with my Pi4, too.
Any ideas or does it even work for anyone?

With rpi-rf receiving works.
But my transmitter module still won't work. Maybe it is defect.
