Light API
The Light service handles a sensor measuring a light intensity in lux.
Its type has access to all common capabilities.
Variables​
| Variable name | Action | Type |
|---|
| lux | Reads the measured light intensity in lux | read only: Float |
| threshold | Thresholds light intensity variation before filter_changed event trigers. Default value 10 lux. | read / write: Float |
| Event name | Trigger |
|---|
| changed | Any movement on the light intensity measurement |
| filter_changed | Movement bigger than threshold |
