Let me rephrase my question then: are there (doorbell) buttons that 1) connect the physical wire to the doorbell, but also 2) send/receive out any wifi or rf443 signal? That way 1) we can press the button on the wall, even when home assistant would be down or having connection issues, AND 2) I can call the “button press” from within home assistant (open the door for someone when I’m not home)
