Edge Node IoT Project

Overview

This repository implements the Node layer of the TechOnIt ecosystem.
Nodes (ESP32/Arduino) connect to the Controller (Raspberry Pi) and relay sensor data and actuator commands.

Features

• Reads data from sensors (temperature, humidity, light, etc.)
• Controls relays and actuators
• Maintains offline operation and caches data
• Receives automation commands from Controller

Architecture

• Node Devices: Collect sensor data, execute commands, provide local safety.
• Controller Node: Aggregates Node data, communicates with cloud, caches automation rules.
• See also:
  • agent-controller
  • agent-sdk

Technologies

• MicroPython for ESP32 / NodeMCU
• Python 3 for Controller
• MQTT, Wi-Fi
• PlatformIO for building Node firmware

Getting Started

1. Connect Node to Wi-Fi network
2. Configure Node with nodeId and Controller endpoint
3. Start Node to begin sending sensor data and receiving commands

Goal

Provide a modular, scalable, and testable edge layer for IoT automation.
