1st post → “what can be shown in a row?”
Already suggested here that if a column must contain foo(x,y) where x,y - different attributes of same entity or attributes/states of different entities - then these data need to be a part of ONE attribute:
- data: Z
modify: >-
... any JS code for Z.X & Z.Y
name: any name
i.e. one attribute Z is a dictionary like:
{
X: some data,
Y: some data
}
For that you will need to create a template sensor.
