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 1.6.0, read the changelog.
- Support for multiple ESP8266-based boards (check list)
- Wifi AP Mode or STA mode with multiple network definitions with support for static IP
- Switch management
- Support for push buttons and toggle switches
- 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
- Report button event notifications
- Enable/disable pulse mode
- Change LED notification mode
- Remote reset the board
- 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
- RPC API (enable/disable from web interface)
- Remote reset the board
- Over-The-Air (OTA) updates even for 1Mb boards
- Manually from PlatformIO or Arduino IDE
- Automatic updates through the NoFUSS Library
- Command line configuration
