The Goal


The goal of this plugin is to generate all the possible combinations of images of a plane created in Sweet Home 3D to, in real time, see the status of the lights in the home assistant.

To achieve this we need to generate a yaml file with the structure of “picture-elements” and generate all the possible combinations of images based on the lights, for example, if we have 3 lights “living_room, kitchen, bed_room”, we need to generate:

light.living_room light.beedrom
0 0 0
0 0 1
0 1 0
0 1 1
1 0 0
1 0 1
1 1 0
1 1 1

As we can see, for 3 lights, there are 2^3 possible combinations, if we have 10 lights, there would be 2^10 combinations -> 1024 images… and we don’t want to generate all the images manually!!

How to use it:

  1. Download the latest release in .jar and copy to Sweet Home 3D “plugins” folder
  2. Give the lights the same name as in Home Assistant, for example, light.living_room
  3. Go to Tools -> Home Assistant Lightning
  4. There are 4 modifiable fields:
  • Path: Path where the images will be generated
  • Image Width: Width of the images to generate (recommended: 380)
  • Image Height: Height of the images to generate (recommended: 285)
  • Quality: Image quality (recommended: high)
  1. Generate images
  2. Move the images to /config/www/planes
  3. Create a card of type picture-elements and paste the generated yaml. 9.Enjoy!!


  • Real-time display of the generation status
  • Migrate project to IntelliJ + kotlin?
  • Error handling
  • Refactorize the code, now it’s a botched job
