REACH — Remote Energy Access and Control Hub

A solar-powered remote energy management system designed for field devices in rural, agricultural, and off-grid environments.

I served as team lead and developed the Particle Boron side of the system, including LTE telemetry and command routing from the remote dashboard to the ESP8266 control hub.

Project Overview

Problem

Remote field locations often rely on solar-powered devices such as sensors, cameras, alarms, and irrigation equipment. These systems can be difficult to monitor and control without visiting the site in person.

REACH was designed to reduce unnecessary field visits by giving users a way to monitor power usage, control connected loads, and respond to low-power conditions remotely.

Solution

REACH acts as an external module between an existing solar power system and connected field devices. It provides remote dashboard control, local diagnostics, outlet scheduling, power monitoring, and load prioritization.

The system combines an ESP8266 local control hub with a Particle Boron LTE communication bridge for remote telemetry and command transfer.

My Role and Contributions

Team Lead; Particle Boron / LTE Telemetry Lead

Team Leadership Particle Boron LTE Telemetry UART Dashboard Commands System Integration
  • Led senior design project coordination, technical planning, task delegation, and integration efforts.
  • Developed the Particle Boron LTE telemetry workflow for communication between the field device and remote dashboard.
  • Implemented command-routing logic to pass dashboard commands from the Particle Boron to the ESP8266 control hub.
  • Supported integration of outlet control, telemetry updates, system status reporting, and dashboard command execution.
  • Contributed to system-level validation for LTE communication, UART messaging, scheduling, telemetry reliability, and hardware/software integration.

System Architecture

Particle Boron

The Particle Boron provided LTE connectivity and acted as the communication bridge between the remote dashboard and the embedded control system.

  • LTE telemetry
  • Dashboard communication
  • Remote command handling
  • Command transfer to ESP8266
  • System status updates

ESP8266 Control Hub

The ESP8266 handled local control logic, outlet switching behavior, local WiFi control, and communication with sensors and output hardware.

  • Outlet control
  • Local WiFi access point
  • Sensor communication
  • Local webpage behavior
  • Command execution from Boron messages

Remote Dashboard

The dashboard allowed users to monitor system status, view power data, control outlets, configure schedules, and set load priorities.

  • Manual outlet control
  • Scheduling
  • Load priority settings
  • Power visualization
  • Battery/system status display

Power and Load Hardware

The hardware integrated with a 12 V solar/battery setup and controlled connected 5 V output ports through switching hardware and sensor feedback.

  • Voltage monitoring
  • Current monitoring
  • MOSFET switching
  • Output protection
  • Power-budget awareness

Testing and Validation

LTE Communication

Verified remote communication behavior through the Particle Boron and confirmed that telemetry could be sent between the field system and dashboard.

Dashboard-to-ESP8266 Command Routing

Tested the command path from the remote dashboard to the Particle Boron and then to the ESP8266 control hub for outlet control and system state updates.

Outlet Scheduling and Load Prioritization

Validated scheduled outlet operation and load-priority behavior during low-power scenarios.

Sensor and Power Monitoring

Tested voltage and current sensing behavior for monitoring connected loads and system power status.

System Integration

Supported full hardware/software integration testing across the dashboard, LTE module, ESP8266, sensors, local display, and output switching hardware.
