ESPurna Firmware

ESPurna ("spark" in Catalan) is a custom firmware for ESP8266 based smart switches. It was originally developed with the IteadStudio Sonoff in mind but now it supports a growing number of ESP8266-based boards. It uses the Arduino Core for ESP8266 framework and a number of 3rd party libraries.

Current Release Version is 1.5.1, read the changelog.

Features

• Support for multiple ESP8266-based boards
• Wifi AP Mode or STA mode with multiple network definitions and static IP support
• Switch management
  • Configurable status on boot (always ON, always OFF, same as before or toggle)
  • Support for pulse mode (normally ON or normally OFF) with configurable time
  • Support for relay synchronization (all equal, only one ON, one and only on ON)
• MQTT enabled
  • Switch on/off and toggle relays
  • Enable/disable pulse mode
  • LED notifications
• Alexa integration using the FauxmoESP Library
• Domoticz integration via MQTT
• Home Assistant integration via MQTT
• Support for different sensors
  • DHT11 / DHT22 / DHT21 / AM2301
  • DS18B20
  • HLW8012 using the HLW8012 Library (Sonoff POW)
  • Non-invasive current sensor using the EmonLiteESP Library (requires some hacking)
• Fast asynchronous HTTP Server
  • Basic authentication
  • Web-based configuration
  • Relay switching and sensor data from the web interface
  • Websockets-based communication between the device and the browser
• REST API (enable/disable from web interface)
  • GET and PUT relay status
  • GET sensor data (power, current, voltage, temperature and humidity) depending on the available hardware
• Over-The-Air (OTA) updates even for 1Mb boards
  • Manually from PlatformIO or Arduino IDE
  • Automatic updates through the NoFUSS Library
• Command line configuration
