I’d like to receive a notification when the value of a sensor has not changed after a given amount of time. Use case is a I have some power monitoring plugs on a GFCI outlet. The GFCI tripped sometime yesterday and the power value flatlined at a non-zero value in Home Assistant.
I was looking at the Device triggers but there is no “power does not change for” trigger. Then I thought a derivative helper with the numeric state set to zero for a set amount of time but didn’t see how to create that trigger. Any help would be appreciated.
