Hi,
I’d like to send a notification to telegram whenever an entity goes unavailable. But i don’t know how tell this to hassio.
I write this automation:
alias: Notify unavailable entities
description: ''
trigger:
- platform: state
entity_id: group.all_devices
to: Unavailable
condition: []
action:
- service: notify.telegram
data:
message: '{{trigger.to_state.attributes.friendly_name}} non è più disponibile'
mode: parallel
max: 10
But group.all_devices doesn’t work
