Items with channels REGEX and JSONPATH

[Josar]

@rlkoshak now i get that i can not add the channel of Exec to an Number item. I just tried to follow up your suggestion, which leaded me to this problem.

@rlkoshak

If you apply the REGEX transform to your GPU temperature thing you can eliminate the Rule entirely.

So basically the Problem is the Exec Binding channel which returns a string and this can not be casted to a Number item. See the documentation.

So that is obvious now.
The return value of the exec binding channel will be stored in the item with applied Regex. In both cases it will be a string. Which can not be stored in the Number item.

Thank you for your time and help, i lost sight of the assignment.

@Kai It would be great to be able to define the return value type when using JSONPATH as it may contain different types of data. Defining the expected return value would match the item type and so the example could work.

This is something that would be implemented by the Binding, not in the core, I believe.

That is apparent, so correcting my thought from above, it would be nice to have an or multiple additional channel at the exec Binding which allows to retrieve a casted value from the returned string.
