Ooh I need to do this. What fan did you use?

Here are the details :

140mm Fan Riser printed in PETG

Smart Plug from SmartPad. I went with the Tuya option even though it's controlled locally by Home Assistant

ID-Cooling AS-140-W 140mm Case Fan

12v Power Supply

*Very important. The 12v Power Supply is not stablized. If less current is drawn, there is a rise in voltage. Given the fan uses so little, that rise is substantial.* In short, set the power supply to 6V. It actually pulls and then sends around 10V to the fan. So the fan spins a bit slower than it could. But it's also more quiet.

Or just use a 12v power supply from an old external disk?

Implemented some Blueprints that Gemini helped me create.
Required some trial & error to get them working the way I wanted, but Gemini is pretty helpful.

Blueprints covering what?

I've found LLMs to be quite good at these things

Using my Shelly Presence Gen4 to determine if there is someone in the room, and if the room is dark enough, then turn on the kitchen or lounge lights for 3 min. Then turn them off.
