I am using the ping test for various devices and have an automation set to notify me of a failure. I also have this listed as a card showing device status but also wold like to know when the ping failed or how long it has been offline. I’ve tried to look for the time since the ping last_triggered with no luck. I also tried setting an input_boolean set to toggle with failures but am not able to get the time it last toggled either. Do these have an event timestamp that can be found?
I found the value as last_changed to use.
