Conditional between multiple entities with an attribute of another entity

Hello folks,

I am working on a blueprint to automate presense detection. It is based on PIR (binary sensors) and ESPresense room occupancy via mqtt_room.

The mqtt_room entities are sensors that output a string corresponding to the room that the tracked device is currently detected to be at.

The particular snippet I am interested in is this:

        - condition: state
          entity_id: !input espresense_devices
          match: any
          state: "{{ state_attr(occupancy_room, 'friendly_name') }}"

In this example, the “entity_id” (!input espresense_devices) is an array of mqtt_room sensors, which all have a string value of the room they are detected at, i.e. “living_room”.

The “state” rule to match, is the “friendly_name” attribute of the custom binary_input entity “occupancy_room”. The value of the “friendly_name” is the exact same string as the one outputted by the mqtt_room, for our example say the value is “living_room”.

I cannot manage to get a match between the multiple presense entities and an attribute of an entity… I’ve tried all sorts of ways and combinations to now avail…

I am pasting the entire blueprint where I am using a variable to use in the “state” property of the condition.

blueprint:
  name: Presense v1
  description: Setups presense automation for a room. This Blueprint will
    Trigger when any of the following happen
    * Any of the binary motion sensors detect motion
    * A tracked device changes room
    Will then turn on presense for the configured room or turn it off
    when there is no person or motion detected.
