value_template: "{{ value_json.data.10041.weekIncidence | int }}"
The only difference I could see is that the value_Template contains a part with only numbers? Might this be a problem? And if so, is there a workaround? Debug only gives me the information that HA gets the same information as I’m getting in the browser, nothing related to some kind of parsing error.
yes, using json_attributes_path and specifying the attributes in json_attributes. All covered in the docs and in the examples in the docs for rest sensors & rest.
