# 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 1.11.4**, read the [changelog](https://bitbucket.org/xoseperez/espurna/src/master/CHANGELOG.md). > **NOTICE**: Default flash layout changed in 1.8.3, as an unpredicted consequence devices will not be able to persist/retrieve configuration if flashed with 1.8.3 via **OTA** from **PlatformIO**. Please check issue #187. > **NOTICE**: since version 1.9.0 the default **MQTT topics for commands have changed**. They all now end with "/set". This means you will have to change your controller software (Node-RED or alike) to send messages to -for instance- "/home/living/light/relay/0/set". The device will publish its state in "/home/living/light/relay/0" like before. ## Features * *KRACK* vulnerability free (when built against Arduino Core 2.4.0 RC2) * Support for **multiple ESP8266-based boards** ([check list](https://bitbucket.org/xoseperez/espurna/wiki/Hardware)) * Power saving options * Wifi **AP Mode** or **STA mode** * Up to 5 different networks can be defined *

SI7021** * **BMP280** and **BME280** temperature, humidity (BME280) and pressure sensor by Bosch * **SI7021** temperature and humidity sensor * **SHT3X** temperature and humidity sensor over I2C (Wemos shield) * **Dallas OneWire sensors** like the DS18B20 * **MHZ19** CO2 sensor * **PMSX003** dust sensor * **BH1750** luminosity sensor * Power monitoring * **HLW8012** using the [HLW8012 Library](https://bitbucket.org/xoseperez/hlw8012) (Sonoff POW) * Non-invasive **current sensor** using **internal ADC** or **ADC121** or **ADS1115** * **ECH1560** power monitor chip * **V9261F** power monitor chip * Raw analog and digital sensors * Simple pulse counter * All temperature sensors support Fahrenheit and Celsius * Support for LED lights * MY92XX-based light bulbs and PWM LED strips (dimmers) up to 5 channels (RGB, cold white and warm white, for instance) * RGB and HSV color codes supported * Manage channels individually * Temperature color supported (in mired and kelvin) via MQTT / REST API * Flicker-free PWM management * Soft color transitions * Color synchronization between light using MQTT * 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 * Works great behind a [secured reverse proxy](http://tinkerman.cat/secure-remote-access-to-your-iot-devices/) * **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 * Works great behind a secured reverse proxy * **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** * Enable/disable via the web UI * 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) * Specific definitions for touch button devices (ESPurna Switch, Sonoff Touch & T1) ## 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.
