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.
- 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
- Over-The-Air (OTA) updates even for 1Mb boards
- Manually from PlatformIO or Arduino Inside
- Automatic updates through the NoFUSS Library
- Alexa integration (requires staging version of Arduino Core for ESP8266)
