Place generic sensors, smart lights, and climate controls. Design your ideal setup without being locked into a specific manufacturer's ecosystem.
Build complex IF/THEN routines. The internal event bus handles time-of-day, triggers, and state changes — just like a real Home Assistant hub.
When the simulation runs perfectly, export your entire node configuration directly into Home Assistant YAML format. Buy only what you tested.
Click and drag to shape rooms, doors, and labels. The grid snaps everything to perfection.
Drag smart devices from the palette into your layout. Visually wire up IF/THEN rule routines.
Hit play to run automations in real time. Test sensor events and verify every rule.
Lighting, sensors, climate control, power management, appliances, and network infrastructure across 5 device layers.
Real-time solar energy output, weather effects, wind triggers, advanced automation rules, and multi-select bulk operations.
Export to PNG and PDF for documentation, network topology visualization, and room templates for rapid iteration.
