I’m looking to trigger an automation if an attributes value changes, trouble is I won’t know the ‘from’ or ‘to’ as its a time-date value.
For example, given the following payload from a ring doorbell last activity;
attribution: Data provided by Ring.com
created_at: '2020-05-05T16:19:14+00:00'
answered: false
recording_status: ready
category: motion
friendly_name: Front Door Last Activity
icon: 'mdi:history'
device_class: timestamp
I basically want to trigger when the created_at attribute changes. Any suggestions?
