New Errors on ALL Rules!

Setup, Configuration and Use Scripts & Rules
1

Hi all,

My rules were working perfectly before, I had my scenes defined so that i can turn lights on and off depending on the scene. I had presence detection working to calculate if I am home and select a scene on the result. Also I have a PIR sensor in my garage which turns on a light if movement is detected but none of this works now.

Nothing has changed except i moved the following from ‘Group Demo’ on the sitemap to the main sitemap screen in its own frame. (since i have reverted back to the original sitemap and still have issues)

Switch item=Scene_General label="Scene" mappings=[0=None, 1=TV, 2=Dinner, 3=Bed, 4=Off]

When ever the scene is changed, presence tries to detect or the garage PIR senses movement i get the following showing in the openhab.log

isn’t mapping should be like that:

Switch item=Scene_General label=“Scene” mappings=[0=‘None’, 1=‘TV’, 2=‘Dinner’, 3=‘Bed’, 4=‘Off’]

3

and for more then on or off, I think you must use:

selection not switch

with an item where you can put all your value, so not a switch item to. (in your xxx.items)

4

But the Scenes have been working fine for weeks.

Ive only started getting issues since yesterday, the issues are the same for other rules which do not relate to the scenes, so i know its not the formatting of my scenes line in the sitemap.

5

I’ve got this sort of problem when I make a mistake in my items file. Is it possible that you make a modification there?

6

Add logging statements at each step of your rule so you can see what line it is failing on. From there you should get a clue as to tge cause. Unfortunately null exception can be caused by a ton of errors.

7

Nah i didnt touch the items file

8

It seems that the rule doesnt even start to run, i added a logging statement at the start but i still get the same error

9

remove all your rules from the directory except one. reboot openhab. see if that rule work.

if it work, add one rule at a time and test it.

You need to isolate the problem. something is preventing your rule to fire up.

Joel,

Thank you for your suggestion.

I moved all of my rules to a separate folder and then put the rules back and now they are working!

Crazy!

Thank you.
