Sonoff-Tasmota v6.4.1

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:

1. Migrate to Sonoff-Tasmota 3.9.x
2. Migrate to Sonoff-Tasmota 4.x
3. Migrate to Sonoff-Tasmota 5.14
4. Migrate to Sonoff-Tasmota 6.x

Release notes

Change in default initial configuration tool

Firmware binary sonoff-classic.bin supports WifiManager, Wps and SmartConfig for initial configuration. The default tool is Wps.

To save memory space all other binaries support WifiManager only.

See _changelog.ino how to enable them again.

• Define WIFI_CONFIG_TOOL now contains the default behaviour once a SSID has been configured.
• If no SSID is configured making a wifi connection impossible the new define WIFI_CONFIG_NO_SSID will be used.
• While define WIFI_CONFIG_NO_SSID is set to WIFI_WPSCONFIG in my_user_config.h the compiler will check for define USE_WPS and if not enabled WIFI_CONFIG_NO_SSID will default to WIFI_MANAGER using the webserver. If define USE_WEBSERVER is also not enabled WIFI_CONFIG_NO_SSID will default to WIFI_SMARTCONFIG. If define USE_SMARTCONFIG is also not enabled WIFI_CONFIG_NO_SSID will default to a new option WIFI_SERIAL allowing to enter wifi parameters to serial which is always possible.

Sonoff-Tasmota v6.2.1

Update 20180909-2100

Thanks to Andre Thomas the latest released binaries work as intended on all hardware.

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:

1. Migrate to Sonoff-Tasmota 3.9.x
2. Migrate to Sonoff-Tasmota 4.x
3. Migrate to Sonoff-Tasmota 5.14
4. Migrate to Sonoff-Tasmota 6.x

Release notes

Change in default initial configuration tool

Firmware binary sonoff-classic.bin supports WifiManager, Wps and SmartConfig for initial configuration. The default tool is Wps.

To save memory space all other binaries support WifiManager only.

See _changelog.ino how to enable them again.

• Define WIFI_CONFIG_TOOL now contains the default behaviour once a SSID has been configured.
• If no SSID is configured making a wifi connection impossible the new define WIFI_CONFIG_NO_SSID will be used.
• While define WIFI_CONFIG_NO_SSID is set to WIFI_WPSCONFIG in user_config.h the compiler will check for define USE_WPS and if not enabled WIFI_CONFIG_NO_SSID will default to WIFI_MANAGER using the webserver. If define USE_WEBSERVER is also not enabled WIFI_CONFIG_NO_SSID will default to WIFI_SMARTCONFIG. If define USE_SMARTCONFIG is also not enabled WIFI_CONFIG_NO_SSID will default to a new option WIFI_SERIAL allowing to enter wifi parameters to serial which is always possible.

Provided Binary Downloads

The following binary downloads have been compiled with ESP8266/Arduino library version 2.3.0

• sonoff-minimal.bin = The Minimal version allows intermediate OTA uploads to support larger versions and does NOT change any persistent parameter. This version should NOT be used for initial installation.
• sonoff-classic.bin = The Classic version allows initial installation using either WifiManager, Wps or SmartConfig.
• sonoff.bin = The Sonoff version without Wps and SmartConfig configuration but adds more sensors.
• sonoff-BG.bin to sonoff-TW.bin = The Sonoff version without Wps and SmartConfig configuration in different languages.
• sonoff-sensors.bin = The Sensors version without Wps and SmartConfig configuration but adds even more useful sensors.
• sonoff-knx.bin = The Knx version without Wps and SmartConfig configuration and some other features but adds KNX support.

See Tasmota ESP/Arduino library version related issues why these files are still released using ESP/Arduino library version v2.3.0.
