Inventory
The preview contains seven lights, two fans, a thermostat, a front-door lock and four appliances across six rooms. Vacuum state, rack temperature and bathroom humidity are additional simulation values rather than separate inventory entities.
Lights expose a 0–100 % level. The thermostat exposes current and target temperature; target changes stay between 15 and 25 °C. Fans expose a level. The lock has a locked state. Appliances report power and a descriptive status; they do not all have manual on/off controls.
Inspect a device
Use Inspect beside a device. The drawer shows its stable entity ID, room, current model state and intended adapter. Related automation rules display their current enabled state. A physical connection is explicitly marked as not connected.
State history contains changes observed since the workspace was opened, bounded by the last 120 session snapshots. Its earliest retained value is a baseline. Opening an inspector later does not manufacture earlier measurements.
Integration models
Light, thermostat and lock controls use the Home Assistant model. Fan and appliance information use the MQTT model. Scripted weather events carry REST labels. These are simulated integration boundaries; no MQTT broker or Home Assistant instance is contacted.
For a future real adapter, a device reading should carry a source, observation time, unit and freshness state. Unavailable telemetry must remain unavailable instead of being replaced by demo values.
Power and sensor values
Power is an estimate calculated from simulated levels and appliance wattages. The starting power graph includes a deterministic illustrative prehistory. It is not an electricity meter, and it does not calculate a bill. Subsequent points come from simulation ticks.
Rack heat and humidity follow bounded scripted rules. The thermostat moves gradually toward its target. These simple models demonstrate causal behavior without claiming physical accuracy.
Before real hardware
The first real integration should be an explicitly selected read-only sensor with its source shown. Public presence, door state and personal occupancy data are outside this preview’s intended public dataset. Actual device control needs an authenticated private workspace and a separate authorization model.
