6. Light Channels & Emerson Effect

Understanding the Emerson Effect

The Emerson Effect is a phenomenon where plants show increased photosynthetic efficiency when exposed to both red and far-red light simultaneously, compared to either wavelength alone.

Scientific Background:

Channel Configuration

ChannelPurposeTiming
Emerson (Red) Far-red spectrum activation
Emerson Effect enhancement
15 minutes before main lights ON
15 minutes after main lights OFF
Full Power (White) Primary plant lighting
Full spectrum illumination
Main photoperiod duration
(18h vegetative / 12h flowering)

Automatic Timing Sequence

  1. Pre-Dawn (15 min before main cycle)
    Emerson channel activates
    Prepares photosystems for main lighting
  2. Main Photoperiod
    Full Power channel ON
    Emerson channel remains ON (synergistic effect)
  3. Twilight (15 min after main cycle)
    Full Power channel OFF
    Emerson channel continues (transition period)
  4. Dark Period
    All channels OFF
    Natural rest period for plants

7. Settings & Configuration

8. Test Mode

Test Mode allows you to verify proper relay operation and lighting system functionality.

Test Sequence

  1. All OFF - Both channels disabled (2 seconds)
  2. Emerson ON - Only Emerson channel active (3 seconds)
  3. Both ON - Full Power + Emerson active (3 seconds)
  4. Full Power ON - Only Full Power channel active (3 seconds)

⚠️ Test Mode Safety

9. Firmware Updates (OTA)

Over-The-Air (OTA) Updates allow you to update the controller firmware wirelessly without physical access to the device.

OTA Update Process

  1. Prepare for Update
    Ensure stable WiFi connection
    Verify adequate power supply
    Have firmware file ready (.bin format)

    Controller enters update mode
    Status LED will indicate OTA readiness
  3. Upload Firmware
    Use compatible OTA tools (PlatformIO)
    Target IP: Controller's current IP address
    Password: Current admin password
  4. Update Completion
    Controller will restart automatically
    Verify new firmware version
    Test all functions after update
