With Node-Red ready, magic happens.

Basic Node-red Workflow Concepts

Understanding the flow is crucial in Node-Red.

  • Nodes: These are the basic building blocks.
  • Flows: Sequences that connect nodes and define tasks.
  • Messages: Information packets sent between nodes.

Create a simple flow to turn on the light with a ‘trigger’ node connected to a ‘light’ node. Define the trigger as your door opening. Link it to your light control node. Deploy the flow and test it.

Watching your light respond instantly to an open door is your first Node-Red win!

Creating Your First Lighting Automation Flow

Welcome to the world of home automation with Node-Red and Home Assistant! Creating your first lighting automation flow can seem daunting, but it’s simpler than you think. There’s something magical about having your lights turn on the moment you open a door. This guide will walk you through each step, from choosing the right nodes to designing the logic that will brighten your home instantly.

Choosing The Right Nodes

Selecting appropriate nodes is crucial for a smooth automation process. The nodes act like building blocks.

  • Events: state node – to monitor your doors.
  • Call the service node – to control your lights.

Designing The Logic For Automated Lighting

The logic is simple: if the door opens – lights on. Keep the steps clear and precise.

  1. Drag an Events: state node onto the canvas.
  2. Set it to listen for the door sensor.
  3. Connect it to a Call service node.
  4. Configure the Call service node to turn on your lights.

Test your flow to ensure it functions correctly. Open a door and watch the magic happen!

Advanced Lighting Scenarios And Triggers

Advanced Lighting Scenarios and Triggers take your smart home to the next level. Pair Node-RED with Home Assistant and watch the magic happen. Lights can turn on when doors open. It’s smart, simple, and energy-efficient. Set the scene for every moment with perfect lighting.

Managing Lighting Based On Time Of Day

Use Node-RED to match lighting with the sun’s cycle. Your home feels natural and comfortable. Lights can fade in at sunrise. They dim down as the sun sets. No switch-flipping is needed.

  • Morning: A gentle, warm light to start your day.
  • Daytime: Bright, energizing light for productivity.
  • Evening: A soft glow for winding down.
  • Night: Dimmed pathways for safety and comfort.

Integrating Motion Sensors For Responsive Lighting

Motion sensors add intelligence to your lighting. Lights respond to your presence automatically. They turn on as you walk into a room. They switch off when there’s no activity. It’s all about convenience and energy savings.

Location Sensor Activation Light Response
Hallways Motion Detected Path lights on
Kitchen Motion at Night Soft glow for snacks
Bedrooms No motion for 30min Lights off, time to sleep
