Blueprints are severely limited because of the llimited templating support for triggers.
I propose in the interim that we add a “target” attribute to the following trigger platforms:
* state
* template
If provided, in addition to the template, look for entity_id's here.
Maybe others:
* tags
* ???
With the limitation that any templates used in the target setup, are only evaluated at configuration time.
Use Case:
Exisitng blueprint example: “Motion Activated Lights” triggered by multiple motion sensors.
