thread Not just lights
Got some switches, Google home mini, door sensors, movement sensors, alarm, IP cameras.
Luckily Xiaomi stuff from China uses the same plug sockets as Australia, so it's pretty cheap.
I like being able to say "night night Google" to turn on the lights, fans and air con upstairs, then wait 5 minutes and turn everything off downstairs.
I also like to know that when my wife inevitably leaves a door open with the aircon on that the ac will auto shut off after a couple of minutes.

Oh and in answer to your question, the light bulbs themselves connect to the raspberry pi
