Nexus System Dashboard & UI Portfolio

Main Home Page UI

Main Control Hub

The primary home screen designed to give an instant overview of the entire system. It provides real-time control and displays active automations seamlessly.

  • 4-CHANNEL CONTROL
    Instantly toggle up to four separate devices or relays directly from the dashboard with zero latency.
  • AUTOMATION VISIBILITY
    Quickly see exactly what automation (like timers or solar schedules) is currently active for each specific device.
  • RESPONSIVE ARCHITECTURE
    Built with asynchronous APIs, allowing the UI state to update instantly without ever requiring a page reload.
Countdown Timer UI

Smart Countdown & Sleep

Intuitive duration-based timers to automate short-term tasks and ensure energy efficiency.

  • COUNTDOWN TIMER
    Set a specific duration (in hours and minutes). The system counts down and toggles the relay when the time expires.
  • SLEEP FUNCTIONALITY
    Ensures heavy-draw devices do not run indefinitely by automatically cutting power after the specified duration is reached.
  • NON-BLOCKING LOGIC
    Engineered with custom millis() tracking, allowing countdowns to process in the background without freezing the system loop.
Solar Automation UI

Solar Automation

A highly advanced automation feature that calculates local sunrise and sunset times directly on the edge device, requiring no active internet connection.

  • OFFLINE CALCULATION
    Uses an onboard DS1307 RTC and complex solar math to autonomously trigger relays based on the sun's position.
  • CUSTOM OFFSETS
    Allows users to add a specific time offset (e.g., turn on lights exactly 30 minutes *before* sunset) for perfect ambient control.
  • SENSOR FUSION
    Hardware integrates seamlessly with I2C BMP280 sensors to cross-reference temperature and pressure data alongside the solar schedule.
Schedule Timer UI

Precision Scheduling

A robust daily routing system allowing users to set absolute clock times for devices to turn on and off.

  • RTC INTEGRATION
    Schedules are strictly tied to the hardware clock, ensuring they execute flawlessly even if the Wi-Fi network goes down.
  • MULTI-CHANNEL ROUTING
    Each of the 4 relay channels can have its own independent schedule programmed directly through the glassmorphic interface.
  • POWER-LOSS RECOVERY
    Variables are safely written to LittleFS/EEPROM, allowing the system to instantly resume schedules after grid power cuts.
Core Settings UI

System Configuration

The administrative backend of the Nexus 4 dashboard, providing deep customization and secure maintenance options.

  • UI CUSTOMIZATION
    Allows users to rename individual channels and adjust the overall dashboard theme color to fit their environment.
  • FACTORY RESET
    Secure commands to wipe EEPROM configurations and reboot the device safely back to factory parameters.
  • AP FALLBACK MODE
    Automatically transitions the device into its own Access Point (AP) if the local router drops, ensuring you never lose control.
Logs and Diagnostics UI

Deep System Diagnostics

A built-in terminal that allows field technicians and users to view the raw state of the microcontroller directly from their phone browser.

  • ACTIVITY FEED
    A rolling log of every action taken by the system, tracking user inputs, automated triggers, and sensor errors.
  • HARDWARE HEALTH
    Displays live Heap memory, I2C bus status, CPU frequency, and Wi-Fi RSSI strength to aid in rapid fault isolation.
  • OTA READY
    Secure boot capabilities allowing over-the-air firmware flashes directly through the local network without physical access.
Nexus 4 Custom PCB Design

Custom PCB Architecture

Engineered from the ground up, the Nexus 4 features a robust, mass-production-ready printed circuit board designed for industrial reliability.

  • HIGH-VOLTAGE ISOLATION
    Strategic component placement and routed PCB isolation slots safely separate the 220V AC mains from the low-voltage ESP logic.
  • INTEGRATED SMPS
    Features a built-in Switch Mode Power Supply section, eliminating the need for external adapters and ensuring stable power delivery.
  • PRODUCTION-READY DFM
    Optimized 2D trace routing, precise footprint mapping, and full 3D modeling ensure a seamless transition from prototyping to mass manufacturing.
