Example Flows

Each example below is a complete Node-RED flow you can import directly. They start from the basic pattern shown in Voice Commands — Inject → Hub → Device → Debug — and scale it out across more devices, more device types, and more downstream handlers.

Multi-room lighting

One hub controlling three lights across different rooms. The bedroom light shows how to extract specific component properties — power state, brightness, and color — into separate debug outputs.

Climate control

A thermostat and ceiling fan on the same hub. The thermostat extracts setpoint, mode, and current temperature into separate outputs. An inject node demonstrates how to send a sensor temperature reading to the thermostat. The fan extracts speed and power state.

Security & access

A lock and a switch acting as an alarm-arm toggle on the same hub, each with its own handler so you can wire in confirmations or notifications.
