I’d like to show a timer time remaining value in a glance card. This is not possible. It would be nice to have an attribute option available, just like the entity card.
Example config:
type: glance
title: Better names
entities:
- entity: timer.waiting_for_topic_response
name: Response
attribute: remaining
tap_action:
action: timer.cancel
Until this gets implemented, you could create a template sensor that extracts the attribute and then use this sensor in your glance card.
Btw, vote for your own request 
That’s very true. Thanks! I wonder if that will be easy to do, as I had trouble with time sensors in the past.
And done! 
Disappointed that it’s not possible, don’t wanna create yet another useless template entity just for display purposes especially that the data is already present as an attribute.
Agreed. Why not just add a simple attribute: within the entity - seems (to me) like a fairly simple addition…?
Why on earth for all other types does a glance card show the actual value, but for a timer it just shows “active”. Not very helpful!
