Hi all,

Since the last update, all my automation failed (see below the error)

I know that the template have been changed, but i’m unable to know what to add to my synthax

Need your help please

Thanks

Error while processing template: Template("{{ as_timestamp(strptime(states("sensor.time_date"), "%H:%M, %Y-%m-%d")) == as_timestamp(strptime(states("sensor.isha_prayer"), "%Y-%m-%dT%H:%M:%S" )) - 900 }}")

Any help please ?
