Sensor to list entities in certain state

Configuration
1

Hi Team,

I am having trouble getting my head around a configuration for my window and door sensors…

  • Right now, each windows has a sensor showing open/close state.
  • I created a helper for the two windows in one room to see if a window is open
  • If I open a window a, the state gets change from closed to open and in the log it shows that window a is open
  • when I open window b now, it doesn’t state that window b was opened
  • when I close window a, state is still opened
  • if I close window b, it logs that window b was closed (but never logged that it was opened) and changes the helper state to closed

I like to achieve:

  • Group for windows
  • Logs all changes of the included windows
  • create either a new sensor or entity that reads all open windows and makes a list for me

Is this by any means achievable? :slight_smile:

Thanks a lot and warm regards
Sebastian

You could show a count of the number of currently open windows and doors. So it’s 1 when ‘a’ is open, and changes to ‘2’ if ‘b’ is opened, and then back to 1 if ‘a’ is then closed. This would give you that count:

{{ states.binary_sensor
  | selectattr('attributes.device_class', 'defined')
  | selectattr('attributes.device_class', 'eq', 'opening')
  | selectattr('state', 'eq', 'on')
  | list
  | count }}

And if you want a sorted list (up to 255 chars) of open devices:

{{ states.binary_sensor
  | selectattr('attributes.device_class', 'defined')
  | selectattr('attributes.device_class', 'eq', 'opening')
  | selectattr('state', 'eq', 'on')
  | map(attribute='attributes.friendly_name')
  | sort
  | join(', ') }}

Thats great thanks a lot :slight_smile:

Could I take this one step further saying:

  • Create a sensor, that both counts and lists entities that have a the open state
  • Like a and b is open
  • Shows “2 open”
  • When I click on it, I get the “more information” dialogue with a list of “HPB window east” & “HPB window south”

Is that possible or to complex? :slight_smile:

Yes it’s possible and it’s only a little more complex than what @michaelblight has already provided. The following assumes you have created a helper group called binary_sensor.kitchen_window_group.

template:
  - sensor:
      - name: Open Kitchen Windows
        availability: "{{ has_value(`binary_sensor.kitchen_window_group`) }}"
        state: >
          {{  state_attr(`binary_sensor.kitchen_window_group`, 'entity_id')
          | select('is_state', 'on') | list | count }} open
        attributes:
          open_windows: >
            {{  expand(state_attr(`binary_sensor.kitchen_window_group`, 'entity_id')
            | select('is_state', 'on') | list) | map(attribute='name') | list | default("None", 1)}}

Thats amazing - thanks a lot for the help, works like a charme :slight_smile:

One final question:

How can I overwrite the text shown like:

  • if 0 => “all closed”
  • if >0 => “1 open”

Thanks again :slight_smile:

        state: >
          {% set open_count =  state_attr(`binary_sensor.kitchen_window_group`, 'entity_id')
          | select('is_state', 'on') | list | count %} 
          {{ iif( open_count == 0, 'all closed', open_count~' open' ) }}
