[SOLVED] Finding the cause of a large exception error when using rules - OH2.4 Stable

Setup, Configuration and Use Scripts & Rules
1

Hi All,

I assume this is rule related as I’m configuring rules.

Any thoughts as to what could cause this?

This is a clue that the error occurred in the block of code of a timer execution.

The problem occurred in an “if” expression

Something turned out to be nul - in the timer execution context.

Important; if you are editing rule files, be aware that any timers already scheduled before the edit will continue to tick away and execute later. At that point they almost always fail with an error just like this, because the edit and reload of the rules file has destroyed the context that they were originally created in.

Not the only cause of this error pattern, but the most puzzling until you have worked it out

Thanks rossko, thats educated me a little on how to find out where the issue lies. if… makes sense!

OK - thanks! I think I know the issue now. These huge errors can be fairly obsecure for a newbie.

So basically, I have a rule that triggers lights and it works well using a single ‘WHEN’ statement to match if the motion sensor changes to ON.

I wanted to use the same rule, to detect if any of 3 motion sensors turns on. I guess a group is a way right?

when 
     member of gMotion changed to ON
then

Yes. I suggest some time with the “Design pattern” posts.

Yep, got it all sorted out and fixed the IF issue! :slight_smile:
