What are some home automation devices that works with RF 433Mhz?

Hi all,
I have SAVVY Smart home system installed in my home

The system operates through RF 433Mhz, I have lighting control, Curtain control, Temperature and etc.

but, they don’t have a smart door lock and water leak sensor.

i’d love to hear your suggestions to where i can get a smart door lock and other home automation devices that works with 433Mhz. any ideas?
