# ESPurna Firmware ESPurna ("spark" in Catalan) is a custom firmware for ESP8266 based smart switches. It was originally developed with the **[IteadStudio Sonoff](https://www.itead.cc/sonoff-wifi-wireless-switch.html)** 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 1.9.2**, read the [changelog](https://bitbucket.org/xoseperez/espurna/src/master/CHANGELOG.md). ## Features * Support for **multiple ESP8266-based boards** ([check list](https://bitbucket.org/xoseperez/espurna/wiki/Hardware)) * Wifi **AP Mode** or **STA mode** * Up to 5 different networks can be defined * Supports static IP * Scans for strongest network if more than one defined * Defaults to AP mode (also available after double clicking the main button) * 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) * Support for **delayed ON/OFF** * **MQTT** enabled * **SSL/TLS support** (not on regular builds, requires staging version of Arduino Core for ESP8266) * 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](https://bitbucket.org/xoseperez/fauxmoesp) * [**Domoticz**](https://domoticz.com/) integration via MQTT * [**Home Assistant**](https://home-assistant.io/) integration via MQTT * Supports MQTT auto-discover feature * [**InfluxDB**](https://www.influxdata.com/) integration via HTTP API * Support for different **sensors** * DHT11 / DHT22 / DHT21 / AM2301 (supports celsius & fahrenheit reporting) * DS18B20 (supports celsius & fahrenheit reporting) * HLW8012 using the [HLW8012 Library](https://bitbucket.org/xoseperez/hlw8012) (Sonoff POW) * Non-invasive current sensor using the [EmonLiteESP Library](https://bitbucket.org/xoseperez/emonliteesp) (requires some hacking) * Raw analog sensor * Fast asynchronous **HTTP Server** * Configurable port * Basic authentication * Web-based configuration * Relay switching and sensor data from the web interface * Handle color, brightness, and white/warm channels for lights * Websockets-based communication between the device and the browser * Backup and restore settings option * Upgrade firmware from the web interface * **REST API** (enable/disable from web interface) * GET and PUT relay status * Change light color (for supported hardware) * 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](https://bitbucket.org/xoseperez/nofuss) * Update from web interface using pre-built images * **Command line configuration** * Change configuration * Run special commands * **Telnet support** * Available only if connected to the AP interface * Show debug info and allows to run terminal commands * **Unstable system check** * Detects unstable system (crashes on boot continuously) and defaults to a stable system * Only WiFi AP, OTA and Telnet available if system is flagged as unstable * Button interface * Click to toggle relays * Double click to enter AP mode (only main button) * Long click (>1 second) to reboot device (only main button) * Extra long click (>10 seconds) to go back to factory settings (only main button) ## Documentation For more information please refer to the [ESPurna Wiki](https://bitbucket.org/xoseperez/espurna/wiki/Home). ## Supported hardware Here is the list of supported hardware.
