Status Sensors
Monitor environmental conditions with temperature and status sensors
Status Sensors
Status sensors provide environmental monitoring capabilities, allowing you to track temperature, light levels, and other conditions in your smart home. We Love Lights displays this information and can use it for automation decisions.
What Are Status Sensors?
Status Sensor Overview
Status sensors are monitoring devices that measure environmental conditions:
- Read-only: They monitor but don't control
- Wireless: Zigbee communication
- Battery powered: No wiring required
- Multi-sensor: Many combine multiple measurements
- Automation input: Use readings for conditional rules
Common Status Sensors
Most status information comes from multi-function devices:

- Primary: Motion detection
- Also includes:
- Temperature sensor: Ambient temperature (°C/°F)
- Light level sensor: Ambient lux measurement
Third-Party Sensors

Temperature in Automation
Use temperature readings for conditional automation:
Example Rules

- And motion detected
- Then turn on fan (via smart plug)
Winter Comfort
- If temperature < 18°C (64°F)
- And time is morning
- Then activate "Warm Lighting" scene
Notification
- If temperature exceeds threshold
- Then send notification (via Shortcuts)
Note: Advanced automation may require Shortcuts app or third-party integration.
Light Level Sensors
Ambient Light Monitoring
Measure room brightness:
Lux Measurement
- Lux: Standard unit of illumination
- Range: 0 (darkness) to 10,000+ (bright sunlight)
- Real-time monitoring
Typical Lux Values
- 0-5 lux: Darkness, night
- 10-50 lux: Dim lighting, twilight
- 50-200 lux: Indoor ambient lighting
- 200-500 lux: Office/work lighting
- 500+ lux: Bright indoor or outdoor
Using Light Level Data
Monitoring
- Track natural light throughout day
- Identify well-lit vs dark areas
- Understand room lighting needs
Optimization
- Adjust artificial lighting based on natural light
- Reduce energy waste
- Maintain comfortable light levels
Light Level in Automation
Primary use: Conditional motion sensor triggers
Motion Sensor Rules
- If motion detected
- And light level < 50 lux (dark)
- Then turn on lights
Benefits
- Don't turn on lights during daytime
- Save energy when natural light sufficient
- Adaptive to seasons (daylight changes)
See Motion Sensors for detailed setup.

- Sufficient for home automation
Light Level Accuracy
- Approximate lux readings
- Relative accuracy more important
- Good for automation thresholds
- Not calibrated light meter
What This Means
- Sensors are reliable for automation
- Don't rely on them for critical applications
- Trends more important than absolute values
Improving Accuracy
Temperature
- Place away from heat sources
- Allow air circulation around sensor
- Don't expose to direct sunlight
- Give sensor time to stabilize (30+ minutes)
Light Level
