Home Assistant Mushroom card templates

templates.yaml

#Showing the state of a temperature in a template card:
{{ states('sensor.your_temperature_sensor') }}

#Change the colour of the light depending on status:
{% if is_state('light.your_light', 'on') %}
  orange
{% endif %}

#Welcome template:
{% set time = now().hour %}
{% if (time >= 18) %}
  Good Evening, {{user}}!
{% elif (time >= 12) %}
  Good Afternoon, {{user}}!
{% elif (time >= 5) %}
  Good Morning, {{user}}!
{% else %}
  Hello, {{user}}!
{% endif %}
  

Old thread, not sure if anyone is interested but if like myself you have setup your full name on HA then it might be worth using (either directly or as a helper):

{{ user.split()[0] }}

Looks cleaner with just the first name and fits better.

I have this code below which is working fine, but I want to make the icon in orange every time that any of these 4 lights below turns on.
light.banheiro_suite_interruptor_iluminacao_interruptor_1
light.banheiro_suite_interruptor_iluminacao_interruptor_2
light.banheiro_suite_interruptor_iluminacao_interruptor_3
light.banheiro_suite_interruptor_iluminacao_interruptor_4

{% if is_state('light.banheiro_suite_interruptor_iluminacao_interruptor_1','on')
%} orange
{% endif %}

Does anybody know how to ADD the "OR" clause on this sintax?
