My initial idea was to keep things as simple as possible. I think micropython is perfect for that.

I started with a thermostat because it has inputs (temperature & humidity), and different outputs (oled 128x64 screen and a relay to turn on/off), and I think it's just one of the most complicated things you will need at home. The rest, starting from this point, would be just easier.

So this is only the beggining. My idea is to make some "typical configurations" of modules that can be used as light switches, light shaders, blinds controllers, appliance controllers, presence control, valve control...

The second phase would be to find a way to integrate all this in a conventional home, without much disturbance. The old switches should work, but you should be able to control the lights from OpenHab. I have some ideas about this that will discuss in the future.

The most important part of the project would be OpenHab. There's where all the "intelligence" should be.

So... why is my project different to others out there doing the same thing?
Because I keep things simple and tidy. The things I'm using are cheap and the less things I can use, the better. (For example, Instead of using RF, I use WiFi).
