ESPurna Firmware

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 1.11.3, read the changelog.

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)
Power saving options
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)
Network visibility
- Supports mDNS (service reporting and metadata)
- Supports NetBIOS, LLMNR and Netbios (when built against Arduino Core 2.4.0 RC2) and SSDP (experimental)
Switch management
- Support for push buttons and toggle switches
- Configurable status on boot per switch (always ON, always OFF, same as before or toggle)
- Support for pulse mode per switch (normally ON or normally OFF) with configurable time
- Support for relay synchronization (all equal, only one ON, one and only on ON)
- Support for MQTT groups to sync switches between devices
- Support for delayed ON/OFF
MQTT enabled
- SSL/TLS support (not on regular builds, see #64)
- Switch on/off and toggle relays, group topics (sync relays between different devices)
- Report button event notifications
- Enable/disable pulse mode
- Change LED notification mode
- Remote reset the board
Alexa integration using the FauxmoESP Library
Google Assistant integration using IFTTT and Webhooks (Google Home, Allo)
Domoticz integration via MQTT
Home Assistant integration via MQTT
- Support for switches (on/off)
- Support for lights (color, brightness, on/off state)
- Supports MQTT auto-discover feature (both switches and lights)
InfluxDB integration via HTTP API
Support for different sensors
- Environment
  - DHT11 / DHT22 / DHT21 / AM2301 / Itead's SI7021 (supports celsius & fahrenheit reporting)
  - 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)

- 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
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
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
- 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)

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)

And of course you can always buy me a beer, coffee, tea,... via the donation button below.
