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 1.2.0, read the changelog.

Features

• Support for multiple ESP8266-based boards (check list)
• Wifi AP Mode or STA mode with multiple network definitions
• MQTT enabled
• Switch on/off and toggle relays
• LED notifications
• Support for different sensors
• DHT11 / DHT22 / DHT21 / AM2301
• DS18B20
• HLW8012 (Sonoff POW)
• Non-invasive current sensor using the EmonLiteESP Library (requires some hacking)
• Fast asynchronous HTTP Server
• Basic authentication
• Web-based configuration
• Relay switching from the web
• Websockets-based communication between the device and the browser
• REST API
• GET and PUT relay status
• Command line configuration
