I used SweetHome3D + Gimp to recreate my whole home!
Lots of measuring and downloading textures and models, but I finally have a digital ‘clone’ of my home!
The lights all react to changes in color and brightness, and are clickable. I made the buttons transparent so it looks cleaner.
Thermostat is in the center, if clicked it opens the thermostat options. The background glow of the temperature turns blue when cooling and red when heating (black when idle)
My 3D Printer can be turned on by clicking on it too, plus it shows the current progress if it is running.
I’d love to see other people’s floorplans for ideas, comment with a pic if you have one set up!


SweetHome3D does that part.
You export an image for every light, where its the only light on. Everything is black except where the light shines. Make those black parts transparent in Gimp or PS.
now when you layer them you have each light’s beams all intersecting and mixing.
There is a background image where all lights are off that they all stack on top of
Its far simpler than you might imagine.
Simple but genius!
Do you set the opacity of a given light layer to the brightness of the real light?
yep! the minimum opacity is set to 40% though, otherwise they look off when dim see my code in another comment reply
