Lighting that responds to the day

Set the crop’s daily light target and permitted lighting hours. HarveStation uses daylight feedback to coordinate supplemental output by zone.

Sun movement, light levels and uniform supplemental lighting are illustrated. Shown during the permitted photoperiod. Actual output depends on the DLI target, available daylight and commissioned settings.
  1. 1

    Measure available daylight at a planned sensor location, accounting for glazing, shade screens and the crop.

  2. 2

    Apply the DLI target, photoperiod and operating days selected for the crop and growth stage.

  3. 3

    Send commands through Zigbee to the zone controller, then adjust compatible fixtures through 0–10V dimming.

Local control coordinates the lighting strategy. Cloud functions provide lighting and environmental records and remote access, subject to the supplied configuration.
