By default, Both EXPRESSION and IF support is disabled. In order to enable IF support, please add these lines in `user_config_override.h`:
- `#define USE_EXPRESSION` // Add support for expression evaluation in rules (+3k2 code, +64 bytes mem)
- `#define SUPPORT_IF_STATEMENT` // Add support for IF statement in rules (+4k2 code, -332 bytes mem)
@ -39,17 +36,17 @@ IF statement supports 3 formats:
- `IF (<condition>) <statement-list> [ELSEIF (<condition>) <statement-list> ] ELSE <statement-list> ENDIF`
`<condition>` is a logical expression, for example:
- `VAR1 >= 10`
- `VAR1>=10`
- Multiple comparison expression with logical operator `AND` or `OR` between them. `AND` has higher priority than `OR`. For example:
`UPTIME > 100 AND MEM1 == 1 OR MEM2 == 1`
`UPTIME>100 AND MEM1==1 OR MEM2==1`
Parenthesis can be used to change the priority of logical expression. For example:
`UPTIME > 100 AND (MEM1 == 1 OR MEM2 == 1)`
`UPTIME>100 AND (MEM1==1 OR MEM2==1)`
`<statement-list>`
- A Sonoff-Tasmota command (e.g.,`LedPower on`)
- Another IF statement (`IF ... ENDIF`)
- Multiple Sonoff-Tasmota commands or IF statements separated by `;`. For example:
`Power1 off; LedPower on; IF (Mem1 == 0) Var1 Var1+1; Mem1 1 ENDIF; Delay 10; Power1 on`
`Power1 off; LedPower on; IF (Mem1==0) Var1 Var1+1; Mem1 1 ENDIF; Delay 10; Power1 on`
`Backlog` is implied and is not required (saves rule set buffer space).
