Error message after server crash

Setup, Configuration and Use Scripts & Rules
1

Hello,

my openhab server failed last weekend. After doing the setup again I am receiving an error in my log which was not there before. Settings are the same because it is from backuped docker volume.

Any ideas where it comes from?

Typically this happens when you just assume that the state of an Item is, for example, a DecimalType or OnOffType or whatever but the Item is actually NULL or UNDEF.

The error tells you exactly which Rule to look in, I don’t understand why you posted them all.

First thing to check is whether Azimuth and Elevation are not NULL or UNDEF.

Not sure how this ever can result in true. :grin:

I notice you don’t use () for the now.getHourOfDay() function. To my knowledge that is the correct syntax, since it is a method.
Are you sure your backup contained the latest status from before the crash?

Rules DSL is a little less strict about this than most languages. If you have a method that doesn’t take any arguments you are not required to use the (). Similarly, if you want to call the getSomething() method, you can just use something, e.g. MyItem.something.

first use of sonne is not defining boolean format …
