Platform error switch.rpi_rf - Integration 'rpi_rf' not found

Hi,
since one of the last HA Updates my rf 433 Switch is not working any more.
I get the error: Platform error switch.rpi_rf - Integration 'rpi_rf' not found.

Also rpi_gpio is not working any more.

Is there a way to get the modules working again? Any alternatives?

Thank you
Chris
