new backup entity - stale trigger or condition

[mellow prawn]

hello,

A new backup entity has been introduced in 2025.4.0b0, called sensor.backup_last_successful_automatic_backup it has the state 2025-03-25T10:56:35+00:00

Just curious, how do I create a trigger for this that triggerns, say if 8 days has passed from the state reported on this new entity (like a backup stale type of thing)

thanks

you could have an automation that runs once a day which then runs a check to see if its stale,

or you could make a binary sensor helper which becomes active when its "stale" then automate off that changing

depends on your goal i guess

something like this could be used as a helper or as a condition. it should return true if the backup age is over 7 days

{{ ( now() - as_datetime( states('sensor.backup_last_successful_automatic_backup') ) ).days > 7 }}
