Timeline on Devices

I have recently reconfigured home assistant to include a large amount of nmap device
Before reconfiguring, when I clicked on a device i could see when it was home and when it was not home in a timeline. Such display no-longer occurs.
Where are the configuration options for this located?
Many Thanks

Do you still have the history component in you configuration?

Thank you, that was missing from the configuration.
Did not see it documented.
