5. Operating Modes
Manual Mode
Direct Control: Manually control each lighting channel independently
- 🔴 Emerson Channel: Far-red spectrum for Emerson Effect
- ⚪ Full Power Channel: Main lighting system
Use Case: Ideal for experimental setups, testing, or when precise timing control is needed.
Auto Mode
Automated Cycles: Pre-programmed lighting schedules for optimal plant growth
- Vegetative Phase: 18 hours light, 6 hours dark
- Flowering Phase: 12 hours light, 12 hours dark
- Emerson Effect: Automatically applied during transitions
Configuration:
- Set start time for light cycles
- Configure weeks for vegetative phase (1-12 weeks)
- Configure weeks for flowering phase (1-16 weeks)
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:
- Discovered by Robert Emerson in the 1950s
- Involves cooperation between Photosystem I and Photosystem II
- Far-red light (700-800nm) enhances red light photosynthesis
- Can increase photosynthetic efficiency by 20-30%
Channel Configuration
Channel | Purpose | Timing |
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
- Pre-Dawn (15 min before main cycle)
Emerson channel activates
Prepares photosystems for main lighting
- Main Photoperiod
Full Power channel ON
Emerson channel remains ON (synergistic effect)
- Twilight (15 min after main cycle)
Full Power channel OFF
Emerson channel continues (transition period)
- Dark Period
All channels OFF
Natural rest period for plants

8. Test Mode
Test Mode allows you to verify proper relay operation and lighting system functionality.
Test Sequence
- All OFF - Both channels disabled (2 seconds)
- Emerson ON - Only Emerson channel active (3 seconds)
- Both ON - Full Power + Emerson active (3 seconds)
- Full Power ON - Only Full Power channel active (3 seconds)
⚠️ Test Mode Safety
- Ensure all lighting systems are properly connected
- Verify power ratings before testing
- Test mode overrides all other settings temporarily
- Normal operation resumes after test completion
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
- Prepare for Update
Ensure stable WiFi connection
Verify adequate power supply
Have firmware file ready (.bin format)
- Access OTA Mode
Click "🔄 OTA Update" button in web interface
Controller enters update mode
Status LED will indicate OTA readiness
- Upload Firmware
Use compatible OTA tools (PlatformIO)
Target IP: Controller's current IP address
Password: Current admin password
