Delving into the realm of home automation with Arduino and Raspberry Pi

Only single click for on and single click for off. All depends on the button count in the sketch.

I didn't end up trying the four buttons at this point in time because I figured I didn't need a separate button for the driveway lights since they operate off the PIR anyway, so I went with 3 and successfully got that working like a charm over wireless. (See pics)

I agree that with four switches you may have to use the daughterboard option given the lack of real estate. I think if you're happy using MQTT etc, then you could easily get away with a single switch for on/off however it's not wrong to use two.
