homebridge-picamera-lightsensor

This is a homebridge plugin which uses the raspberry-pi camera to emulate a ambientlight sensor

Configuration

"accessories": [
   {
   	"accessory": "PiCameraLightsensor",
   	"name": "LightSensor",
   	"poll_interval": 300
   }
]

### Parameter

• poll_interval: seconds between measurements (default: 300)
• from_left_percent: left edge from where the calculation should start (default: 0)
• to_right_percent: right edge where the calculation should end (default: 100)
• from_top_percent: top edge from where the calculation should start (default: 0)
• to_bottom_percent: bottom edge where the calculation should stop (default: 100)

The following configuration example uses the top/right quarter of the image for the brigthness-calculation

"accessories": [
  {
  	"accessory": "PiCameraLightsensor",
  	"name": "LightSensor",
  	"poll_interval": 300,
  	"from_left_percent": 50,
  	"to_right_percent": 100,
  	"from_top_percent": 0,
  	"to_bottom_percent": 50,
  }
]
