Hi,

i’m having the following problem
i’m using the http binding in openhab 3.1 to get a value
this seems to be working and returns a string in this format

{“EUR”:27989.37}

when try to use json to get only the numbers 27989.37 i can’t get it to work
i’m sure i’m making a stupid mistake but can’t seem to figure it out
code below, any help would be appreciated

What do your logs say? Have you installed the JSONPATH add-on?
