Laurent Dong 96098e4e09 Support If in Rules 
The major features of IF statement are:
 - Support IF, ELSEIF, ELSE
 - Support not only comparison but also using logical expression as condition
 - Support run multiple commands
 - Support nested IF statement
 - All the commands run by IF statement will go to the BACKLOG!
 - No limit for logical operators, parenthesis and nested IF statement. Depends on your RAM!

Extended Backus-Naur Form of IF statement:
<if-statement> ::=
IF "(" <logical-expression> ")" <statement-list> {ELSEIF "(" <logical-expression> ")" <statement-list>} [ELSE <statement-list>] ENDIF
<logical-expression> :=
<comparison-expression> |
(<comparison-expression> | <logical-expression>) {(AND | OR) <logical-expression>} |
"(" <logical-expression ")" {(AND | OR) <logical expression>}
<comparison-expression> ::=
<math-expression> ("=" | "<" | ">" | "|" | "==" | "<=" | ">=" | "!=") <math-expression>
<statement-list> ::=
<statement> {";" <statement>}
<statement> ::=
<Sonoff-Tasmota-command> | <if-statement>

In English:
If statement support 3 format:
1. IF (<condition>) <statement-list> ENDIF
2. IF (<condition>) <statement-list> ELSE <statement-list> ENDIF
3. IF (<condition>) <statement-list> [ELSEIF (<condition>) <statement-list> ]* ELSE <statement-list> ENDIF

<condition> is a logical expression which can be:
1. A comparison expression for example:
   VAR1 >= 10
2. Multiple comparison expression with logical operator "AND" or "OR" between them. "AND" has higher priority than "OR". Fox example:
   UPTIME > 100 AND MEM1 == 1 OR MEM2 == 1
3. Parenthesis can be used to change the priority of logical expression. For example:
   UPTIME > 100 AND (MEM1 == 1 OR MEM2 == 1)

<statement-list> can be:
1. A Sonoff-Tasmota command. For example:
   ledpower on
2. A IF statement ("IF .... ENDIF")
3. Multiple Sonoff-Tasmota command or IF statement split with ";". For example:
   Power1 off; Ledpower on; if (mem1 == 0) Var1 Var1+1; mem1==1 endif; Delay 10; POWER1 on
4. Do not need to lead with "BACKLOG" for multiple commands.

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.

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

Dev Version Download Dev Build Status

See sonoff/_changelog.ino for detailed change information.

The development codebase is checked hourly for changes and if new commits have been merged and compile successfuly they will be posted at http://thehackbox.org/tasmota/ (this web address can be used for OTA too). It is important to note that these are based on the current development codebase and it is not recommended to flash it to devices used in production or which are hard to reach in the event that you need to manually flash the device if OTA failed. 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).

Disclaimer

⚠️ DANGER OF ELECTROCUTION ⚠️

A Sonoff 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 Sonoff device 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 version 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.

Version Information

  • Sonoff-Tasmota provides all (Sonoff) modules in one file and starts with module Sonoff Basic.
  • Once uploaded, select Module using the configuration webpage, the commands Modules and Module or configure the Template for your device
  • After reboot select config menu again or use commands GPIOs and GPIO to change GPIO with desired sensor.

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
