Rules and IF statements

[tsunfinger]

using Tasmota 13.3.0 on shelly and playing with rules. Can somebody give a hint please, why this rule isn't working as expected?
single command on this rule is working (only "var5 55" instead of "var5 55; var6 22")

rule2
on var2#state do
backlog0 IF (%var4% == 1) var5 55; var6 22 ENDIF; var7 11
endon

var4 2
18:02:37.905 RUL: VAR2#STATE performs "backlog0 IF (2 == 1) var5 55; var6 22 ENDIF; var7 11"
18:02:37.960 MQT: stat/tasmota_4F9978/RESULT = {"If":"Done"}
18:02:37.976 MQT: stat/tasmota_4F9978/RESULT = {"Var6":"22 ENDIF"}
18:02:37.990 MQT: stat/tasmota_4F9978/RESULT = {"Var7":"11"}

var4 1
18:04:12.134 RUL: VAR2#STATE performs "backlog0 IF (1 == 1) var5 55; var6 22 ENDIF; var7 11"
18:04:12.198 MQT: stat/tasmota_4F9978/RESULT = {"If":"Done"}
18:04:12.210 MQT: stat/tasmota_4F9978/RESULT = {"Var6":"22 ENDIF"}
18:04:12.223 MQT: stat/tasmota_4F9978/RESULT = {"Var7":"11"}

Remove 'backlog0' as not required and probably the reason for your problems

[tsunfinger]

ok, but in this case var7 won't be set
any idea for a workaround? set var7 twice - inside IF statement and after with ELSEIF?

[barbudor]

As suggested in docs

The Backlog command does not play very well with IF/ENDIF. Seeing {"Var6":"22 ENDIF"} means that the parsing broke down, and the Var command was outside the parsing for ENDIF to match the IF.

If you insert an extra ; the parsing of IF/ENDIF is no longer broken. This could be any other command, but no command is just an empty command, and therefore can work.

rule2
on var2#state do
backlog0 ; IF (%var4% == 1) var5 55; var6 22 ENDIF; var7 11
endon

I'm not sure if this is a generally robust solution, but it worked in this specific case at least.

this workaround seems to be running. I built something with ELSEIF but doesn't seems to be running as well
rule2 on var1#state do IF (%value% == 1) var5 55; var7 77 ELSEIF var7 77 ENDIF endon

08:18:57.922 CMD: var1 2
08:18:57.927 MQT: stat/tasmota_4F9978/RESULT = {"Var1":"2"}
08:18:57.949 RUL: VAR1#STATE performs "IF (2 == 1) var5 55; var7 77 ELSEIF var7 77 ENDIF"
08:18:57.953 MQT: stat/tasmota_4F9978/RESULT = {"If":"Done"}
08:19:12.515 CMD: var1 1
08:19:12.519 MQT: stat/tasmota_4F9978/RESULT = {"Var1":"1"}
08:19:12.545 RUL: VAR1#STATE performs "IF (1 == 1) var5 55; var7 77 ELSEIF var7 77 ENDIF"
08:19:12.550 MQT: stat/tasmota_4F9978/RESULT = {"If":"Done"}
08:19:12.768 MQT: stat/tasmota_4F9978/RESULT = {"Var5":"55"}
08:19:13.018 MQT: stat/tasmota_4F9978/RESULT = {"Var7":"77"}

[sfromis]

To be valid syntax, that should be ELSE instead of ELSEIF, as you have no new condition.

Ah sry, stupid copy&paste error from my site. Yes
rule2 on var1#state do IF (%value% == 1) var5 55; var7 77 ELSE var7 77 ENDIF endon
is working as expected
