Update entity color based on attribute

1

Hi.

I am trying to set the icon color for the entities defined by the yahoofinance integraion. They are in the form yahoofinance.stock_name. Each entity provides an attribute called ‘trending’. I wish to set the icon color for each entity based on this attribute. Now, two questions:

  1. I want to define a group which holds all of these stock entities. Rather than listing each entity individually, can I do something like yahoofinance.*?
  2. What template should I write to achieve this? How can I apply the template to the group rather than repeating the code for each entity? I probably have to use expand somewhere.

I have tried this w/o luck in customize.yaml

 yahoofinance.tsla:
  friendly_name: TSLA
  templates:
    icon_color: >
      if (is_state_attr('yahoofinance.tsla','trending','up') return [0,255,0];
      return [255,0,0];

I have also tried rgb_color instead of icon_color.

Thanks

I can’t help with that integration, but if that integration exposes sensors then you could you something like the button-text-card:

  [[[
    if(states["sensor.purpleair_aqi_a"].state > 300){

      return 'white';
    } else if(states["sensor.purpleair_aqi_a"].state > 150){
