Four years ago I presented at CLUG on my custom home automation system. It's taken a long time, but in case anyone's keen to see, I have finally made some progress towards a prototype of my smart light switch. It uses an ESP with a custom PCB that my brother Tim made, has momentary push button switches as inputs to GPIO and has a PIR sensor, etc. The ESP has a bunch of MOSFETs which lets the ESP control the relay, which turns on the respective 240V circuit.

No blog post yet but you can see it on twitter[1] with a couple of videos of it installed in the bathroom. I also have an old blog post series[2] similar to what I talked about at CLUG, if you're interested in the backstory.
