Create an alert, based on various conditions

Configuration
1

hey all,
i want to have a list of stuff, that if “true” i would get an alert.

eg.
if the car is set to “unlocked” or
the downstairs door is “open”
or the back side gate is “open”
or the office window is “open”
or the pc is powered “on”
or etc…etc…

these would collect as a list and display in a card (those which are valid/triggered)

the idea being that at night, when i trigger my goodnight switch, a light would flash to let me know that something is wrong, before going to bed and i could check the list of things i need to resolve.

not sure where to start here with this grouping…

Did you already see the Entity filter card?
If you set Show empty to False you will only get a list when one or more of the specified entities is in the required state.

I think @thusassistint gave you a very good precise answer to your need. The entity filter card is a great way to achieve your goal. Another good one is the multiple entities row custom card that lets you really refine your list - I tend to use this quite a bit in HA and consider it one of my core components.
