- # 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 [changes log](https://bitbucket.org/xoseperez/espurna/src/master/CHANGELOG.md).

- ## Notices
-
- ---
- > **2017-08-26**: 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.
-
- ---
- > **2017-07-24**: 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.

- ## Contribute
-
- There are several ways to contribute to ESpurna development. You can contribute to the repository by doing:
-
- * Pull requests (fixes, enhancements, new features... are very welcome)
- * Documentation (I reckon I'm bad at it)
- * Testing (filing issues or help resolving them, they take a lot of time and sometimes I don't have the required hardware to test them all)
