I have a door sensor such as below:
Now, what I want to do, rather than only showing the door is closed (below), I want it to show that it has been closed for “x hours ago”. That information exists according to the picture above, so how do I extract it?
Add secondary_info: last-changed to your entity in the entities card.
secondary_info: last-changed
This is perfect.
Just wondering, is it possible to have the specific date and time of when that happened (the “last changed”)?
There’s also a custom-card for the secondary info.
