Alternative firmware for ESP8266 based devices like iTead Sonoff with web, timers, 'Over The Air' (OTA) firmware updates and sensors support, allowing control under Serial, HTTP, MQTT and KNX, so as to be used on Smart Home Systems. Written for Arduino IDE and PlatformIO.
If you like Sonoff-Tasmota, give it a star, or fork it and contribute!
Current version is 5.14.0b - See sonoff/_releasenotes.ino for change information.
Download one of the released binaries from https://github.com/arendst/Sonoff-Tasmota/releases and flash it to your hardware as documented in the wiki.
If you want to compile Sonoff-Tasmota yourself keep in mind the following:
- Only Flash Mode DOUT is supported. Do not use Flash Mode DIO / QIO / QOUT as it might seem to brick your device. See Wiki for background information.
- Sonoff-Tasmota uses a 1M linker script WITHOUT spiffs 1M (no SPIFFS) for optimal code space. If you compile using ESP/Arduino library 2.3.0 then download the provided new linker script to your Arduino IDE or Platformio base folder. Later version of ESP/Arduino library already contain the correct linker script. See Wiki > Prerequisite.
- To make compile time changes to Sonoff-Tasmota it can use the
user_config_override.hfile. It assures keeping your settings when you download and compile a new version. To useuser_config.override.hyou will have to make a copy of the provideduser_config.override_sample.hfile and add your setting overrides. To enable the override file you will need to use a compile define as documented in theuser_config_override_sample.hfile.
- Sonoff-Tasmota provides all (Sonoff) modules in one file and starts with module Sonoff Basic.
- Once uploaded select module using the configuration webpage or the commands
ModulesandModule. - After reboot select config menu again or use commands
GPIOsandGPIOto change GPIO with desired sensor.
See Wiki for more information.
See Community for forum and more user experience.
