"Entities problem" sensor


I want to build a sensor “sensor.problems_any” that switches to true as soon as an (any) entity enters a certain state, typically “unknown” or “unavailable”.

Thereby various entities have to be excluded (they might be on the whitelist but if a certain attribute is of a specific state the whole entity needs to be excluded).

Currently I use all this via custom card “auto-entities” in the GUI (see yaml below), but I can’t get this syntax-wise with all the distinctions into a YAML-compliant sensor definition. I´m thinking of a template sensor but I´m looking for the set of right querys.

Specific questions:

  1. Can I use wildcards with “is_state”?
  2. How can I define exclusions? So e.g. "everything with state ‘unknown’ except the attribute ‘source_type’ has the value ‘gps’ "? (so it´s a blacklist within a whitelist query)

Example what I currently use for a Lovelace card:

type: custom:auto-entities
  type: entities
  title: ⚠ Probleme
  state_color: true
  show_header_toggle: false
    - state: unavailable
    - state: unknown
          source_type: gps
    - domain: binary_sensor
        device_class: problem
      state: 'on'
    - entity_id: group.*
    - entity_id: '*geocoded_location'
    - entity_id: media_player.fire_tv_4k_stick
show_empty: false
unique: true
  method: name
  reverse: false

Thankful for all input :v:

Here is a thread dealing with that exact topic:

No reason to re-invent the wheel. :wink:

Thanks, I also meanwhile discovered Unavailable Sensor Detection and Notification · GitHub and am trying to adopt it to my needs.

Maybe I‘ll get some additional inspiration by your link too. :slightly_smiling_face:

Update: Ha! It’s even the same source :joy::ok_hand:t3:
