homeassistant

This is a great case for templates. Templates are Home Assistant's way of doing dynamic actions or data.

When: whatever triggers you need for the lights - can be multiple triggers or one trigger with every light/switch listed, with a For clause. The list is "OR"ed so do however you want. You could use a group but then all devices would be changed together - which doesn't sound like is what you want.

And if: Whatever conditions you want, time, day of week, etc.

Then do: The action is where it gets interesting add an action to execute "Generic turn off", select any device (we'll change that in a moment). The reason for the "Generic turn off" is that it works with devices in any domain (light or switch). Then drop into the YAML view and chcange the entity_id value to this template: '{{ trigger.from_state.entity_id }}'. The trigger is a variable that's available inside the automation and can be used instead of specifying a static value somewhere. https://www.home-assistant.io/docs/automation/trigger/ for details on triggers.

Here's the complete automation, you could create a new empty automation, then copy and paste this in place and just change the trigger and conditions as you want.
