I like Sweet Home 3D. I’m slowly building my house’s floor plan and laying out furniture using it. Just using it sporadically once every few weeks. It’ll be done eventually.
I’m hoping to use it in Home Assistant with ha-floorplan (experiencelovelace.github.io/ha-floorplan/) so that I can have a floor plan with things overlaid on it (lights, temperature, etc) that you can tap to toggle.
