Sonoff-Tasmota

Alternative firmware for ESP8266 based devices like iTead Sonoff with web UI, rules and timers, OTA updates, custom device templates and sensor support. Allows control over MQTT, HTTP, Serial and KNX for integrations with smart home systems. Written for Arduino IDE and PlatformIO.

If you like Sonoff-Tasmota, give it a star, or fork it, and contribute!

See RELEASENOTES.md for release information.

In addition to the release webpage the binaries can also be downloaded from http://thehackbox.org/tasmota/release/

Development

See sonoff/_changelog.ino for detailed change information.

Unless your Tasmota based device exhibits a problem or you need to make use of a feature that is not available in the Tasmota version currently installed on your device, leave your device alone - it works so don't make unnecessary changes! If the release version (i.e., the master branch) exhibits problems for your device and configuration, you should upgrade to the latest development version instead to see if your problem is resolved.

The Tasmota development codebase is checked every 1-2 hours for changes. If new commits have been merged and they compile successfuly, new binary files for every variant and Core will be posted at http://thehackbox.org/tasmota/ (this web address can be used for OTA too). The last compiled commit number is also posted on the same page along with the current build status (if a firmware rebuild is in progress). It is important to note that these binaries are based on the current development codebase. These commits are tested as much as is possible and are typically quite stable. However, it is infeasible to test on the hudreds of different types of devices with the specific configurations that are permitted.

Note that there is a chance, as with any upgrade, that the device may not function as expected. You must always account for the possibility that you may need to flash the device via the serial programming interface if the OTA fails. Even with the master release, you should always attempt to test the device or a similar prototype before upgrading a device which is in production or is hard to reach. And, as always, make a backup of the device configuration before beginning any firmware update.

⚠️ DANGER OF ELECTROCUTION ⚠️

An ESP82xx Wi-Fi device is not a toy. It uses Mains AC so there is a danger of electrocution if not installed properly. If you don't know how to install it, please call an electrician. Remember: SAFETY FIRST. It is not worth risk to yourself, your family, and your home if you don't know exactly what you are doing. Never try to flash a device using the serial programming interface while it is connected to MAINS AC.

We don't take any responsibility nor liability for using this software nor for the installation or any tips, advice, videos, etc. given by any member of this site or any related site.

Note

Please do not ask to add new devices unless it requires additional code for new features. If the device is not listed as a module, try using Templates first. If it is not listed in the Tasmota Device Templates Repository create your own Template.

Quick Install

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.

Important User Compilation Information

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 versions of ESP/Arduino library already contain the correct linker script. See Wiki > Prerequisites.
To make compile time changes to Sonoff-Tasmota it can use the user_config_override.h file. It assures keeping your settings when you download and compile a new version. To use user_config.override.h you will have to make a copy of the provided user_config_override_sample.h file and add your setting overrides. To enable the override file you will need to use a compile define as documented in the user_config_override_sample.h file.

Configuration Information

Please refer to the Installation and configuration articles in the wiki.

Migration Information

See wiki migration path for instructions how to migrate to a major version. Pay attention to the following version breaks due to dynamic settings updates:

Migrate to Sonoff-Tasmota 3.9.x
Migrate to Sonoff-Tasmota 4.x
Migrate to Sonoff-Tasmota 5.14
Migrate to Sonoff-Tasmota 6.x
