I tried to reject some entities from my counter sensor, but it does’t work for me.
- platform: template
sensors:
count_media_players:
friendly_name: "Количество включенных плееров"
value_template: >-
{{ states. media_player
|rejectattr ("attributes.entity_id", "defined")
|selectattr ('state', 'in', ['on','paused', 'playing', 'idle'])
|reject ('in', ['media_player.evo_150_2','media_player.spotify','media_player.plex_plex_for_android_tv_mibox_s'])
|list | count }}
