OpenBeken CH22 Less Than CH23 Syntax for SetChannel 12 0

User question

syntax if $CH22 <$CH23 then SetChannel 12 0

Artificial Intelligence Response

Direct answer to the question

For OpenBeken scripting, write it like this:

if $CH22<$CH23 then "SetChannel 12 0"

The important part is that the command after then should be quoted because it contains spaces:

"SetChannel 12 0"

So your intended logic is:

If channel 22 is less than channel 23, set channel 12 to 0.

Detailed problem analysis

Your original line was essentially:

if $CH22 <$CH23 then SetChannel 12 0

or, with HTML escaping:

if $CH22 <$CH23 then SetChannel 12 0

In actual OpenBeken script syntax, < must be written as the real less-than character:

<

So the comparison should be:

$CH22<$CH23

The corrected full command is:

if $CH22<$CH23 then "SetChannel 12 0"

The quotes are needed because SetChannel 12 0 is one command with arguments. Without quotes, the script parser may treat SetChannel, 12, and 0 as separate tokens belonging to the if statement rather than as the command to execute.

Recommended robust version

If you will use this logic more than once, define an alias:

alias CheckCH if $CH22<$CH23 then "SetChannel 12 0"

Then call it with:

CheckCH

If you want it to run repeatedly, for example every second:

alias CheckCH if $CH22<$CH23 then "SetChannel 12 0"
addRepeatingEvent 1 -1 CheckCH

Or, if you want it to run when either channel changes:

alias CheckCH if $CH22<$CH23 then "SetChannel 12 0"
addChangeHandler Channel22 CheckCH
addChangeHandler Channel23 CheckCH

---

Practical guidelines

Use this if the condition should be checked only once, for example at boot:

if $CH22<$CH23 then "SetChannel 12 0"

Use this if it should be checked continuously:

alias CheckCH if $CH22<$CH23 then "SetChannel 12 0"
addRepeatingEvent 1 -1 CheckCH

Use this if it should react only when channel 22 or 23 changes:

alias CheckCH if $CH22<$CH23 then "SetChannel 12 0"
addChangeHandler Channel22 CheckCH
addChangeHandler Channel23 CheckCH

---

Brief summary

Correct syntax:

if $CH22<$CH23 then "SetChannel 12 0"

Do not use < in the actual script. Use the real < symbol. Quote the command after then because SetChannel 12 0 contains spaces.
