Lesson 3 Video Description: The Open and Shut Case
Welcome to CraftingTable Academy – Month 4, Lesson 3!
In this lesson, we’re adding door and window sensors to your smart home setup—letting your system react when something opens or closes.
Here’s what you’ll cover today:
✅ Pair and configure your 1x Zigbee door and window sensor in Home Assistant
✅ Mount sensors correctly on doors, windows, or cabinets for reliable detection
✅ Understand sensor states (open vs. closed) and how they show up in your dashboard
✅ Create basic automations, like turning on a light when the door opens
✅ Log sensor events over time and track how often doors or windows are used
✅ Bonus Challenge: Build a simple security system using your sensors, RGB lights, and notifications (for example, flashing a red light or playing a sound if a door opens when you’re away)
💡 What You Need for This Lesson:
- 1x Zigbee door/window sensors
- Zigbee-integrated Home Assistant setup (from previous lessons)
- Optional: RGB bulbs or plugs for automations
- Home Assistant dashboard access
By the end of this lesson, you’ll have smart sensors monitoring your home, triggering automations, and giving you new ways to interact with your space.
