i don't get what i'm doing wrong. i'm trying to use the call service node in home assistant to trigger:
entity id: light.master_bedroom
data: "brightness_pct": "100", "kelvin": "2700"
the json editor is complaining 'invalid json: syntaxerror: unexpected token : in json at position 16' in my data field. with the pages of light service data nomenclature that's plastered all over the call service node properties screen it would be nice if there was 1 syntax example.
