I am trying to define a static array variable and thought it will go within config.yaml file
adding the below at the end of the file, the editor complains of ‘missed comma between flow collection entries YAML’
Actually I need it be available within a lovelace card, and perhaps this code’s place is not in configuration.yaml
{% set test_var = ['00','01','11','10'] %}
Some similar questions gravitated toward a stray tab character within the rest of the file or other formatting issues.
In real world, I am trying to create some sensor groups like in the code below, but I exemplified and replicated the same error with my simple example: {% set test_var = [‘00’,‘01’,‘11’,‘10’] %}
