Motion-Activated Lighting with Home Assistant \u2014 Local, No Cloud<\/h2>\n\n\n\n

Introduction<\/strong>
This is a simple and reliable way to turn on lights automatically when motion is detected using Home Assistant.
The goal is to keep everything local<\/strong>, fast, and independent from cloud services.
This setup works well for hallways, bedrooms, bathrooms, or entry points.

What you need<\/strong>
Home Assistant running (Raspberry Pi, NUC, etc.)
A motion sensor (Zigbee or WiFi)
A smart light or smart relay (Zigbee or WiFi)
Recommended:
Zigbee motion sensor (more stable, lower latency)
Zigbee light switch or smart bulb

Basic concept<\/strong>
The logic is simple:
If motion is detected \u2192 turn light ON
If no motion for X minutes \u2192 turn light OFF

Step-by-step setup<\/strong>
1. Add your devices to Home Assistant<\/strong>
Make sure:
Motion sensor appears as a binary sensor (motion \/ no motion)
Light appears as a controllable entity (switch or light)
Example:
binary_sensor.hallway_motion
light.hallway_light

2. Create the automation<\/strong>
Go to:
Settings \u2192 Automations \u2192 Create Automation<\/strong>

Trigger<\/strong>
Type: State
Entity: motion sensor
To: on

Action<\/strong>
Type: Turn on light
Entity: your light

3. Add auto-off delay<\/strong>
Add a second automation OR extend the first one:
Trigger:
Motion = off
For: 5 minutes (adjust as needed)
Action:
Turn off light

Recommended improvement (important)<\/strong>
Instead of instant OFF, always use a delay:
Bathroom: 2\u20135 min
Hallway: 1\u20133 min
Bedroom: 10\u201315 min
This avoids flickering lights when you are still in the room.

Common mistakes<\/strong>
\u274c Motion sensor too sensitive<\/strong>
\u2192 leads to constant toggling
\u274c No delay before turning off<\/strong>
\u2192 lights turn off while still inside
\u274c Mixing cloud devices<\/strong>
\u2192 introduces lag and instability

Advanced idea (optional)<\/strong>
If you want better behavior:
Add \u201csun condition\u201d
Only activate when it is dark
Condition example:
If sun is below horizon \u2192 allow automation

Conclusion<\/strong>
This setup is one of the simplest but most useful automations in Home Assistant.
It improves comfort, reduces manual switching, and works fully locally without dependency on external services.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
