RF motion sensor - how to start?

Configuration
1

-Hi,

I have Raspi3 with RXB6 433MHz receiver. Cheap chinese IR motion sensor (not sure if it sends ON status only)

1, Which PIN on Raspi3 should I connect DATA from RXB6 ?

2, Should I set the sensor (they will be 4) as switch or sensor or something else?

3, Which component to use?

Thank you very much!

You need a bit more to decode the 433Mhz signals to be used in Home Assistant.
You could use RFLink for this.

This involves a bit more hardware.

Are you sure? Some people here use cheap RF receivers without any additional HW. Check here https://youtu.be/5UUazFbK-Hg
