PROJECT DESCRIPTION

ESPEasy is an open-source firmware designed to run on low-power microcontrollers such as the ESP8266 or ESP32, which are commonly used in Internet of Things (IoT) devices. It allows users to easily connect and manage various sensors and actuators without needing extensive programming knowledge. ESPEasy is primarily used in applications like smart homes, environmental monitoring, and industrial automation.

Key Features and Characteristics

Sensor and Actuator Support:

  • ESPEasy supports a wide range of sensors, including temperature, humidity, light, and pressure sensors, as well as actuators like relays and motors.

Web-Based Interface:

  • It provides a web-based interface for configuration and management. Users can easily access the device through a web browser to monitor sensor readings or adjust settings.

Protocol Support:

  • ESPEasy supports various communication protocols such as MQTT, HTTP, HTTPS, and UDP, enabling integration with other IoT platforms and data transmission.

Extensibility:

  • With multiple plugins and integration options, it’s easy to extend the functionality by adding more sensors or features.

OTA (Over-the-Air) Updates:

  • The firmware can be updated wirelessly, making it convenient to manage devices that are physically difficult to access.

Local Automation:

  • Devices can be set up for local automation, allowing them to perform automated tasks even without an internet connection.

Use Cases

  • Smart Home Automation: For example, using temperature and humidity sensors to monitor indoor conditions and automatically control air conditioning or heating systems when specific criteria are met.
  • Environmental Monitoring: ESPEasy can be used to monitor air quality, soil moisture, and other environmental factors, sending data to the cloud for analysis.
  • Remote Control: It allows remote control of devices such as relays and motors via a web interface or through integrated platforms like MQTT.

Ethernet

ESP boards can be equiped with Ethernet. This is more stable and reliable compared to WiFi and allows for better responsiveness.

Actual transfer speed (at least when using RMII) is also higher than can be achieved via WiFi, but this is less of a concern for typical use cases where ESPEasy is used.

Ethernet chips/boards for ESP32-variant boards exist with 2 types of interfaces to the ESP.

RMII interface - Faster actual transfer speeds possible, uses more GPIO pins, only supported on ESP32-classic (and upcoming ESP32-P4).

SPI interface - (Added: 2024/02) Supported on all ESP32-variants (not all tested) on builds based on ESP-IDF 5.1 SPI Ethernet adapters do obviously require the SPI interface to be configured.

N.B. Only ESP32-variant builds with LittleFS support SPI Ethernet. (starting February 2024)
