Show timer duration in Bubble card

Hi, i made a bubble card to control my ceiling fan. i use a tuya smart IR remote and i used the tuya app to setup scenes to make the remote compatible with HA. I created a some scripts in HA to create this timer function. I want to know if it’s possible to show the remaining time of a timer. for example in this seperator where it says ‘time remaining’

Depending on how you created the timer, it should be an entity you can display in the card. Did you use a Helper - Timer to to create the timer?

That can be displayed as a entity

07-09-42-37-217 - chrome

type: entities
entities:
  - entity: timer.nanoleaf_morning

In the above example the timer is triggered at a time of day via a automation

This doesnt work the time remaing attribute is shown as static

i think you’d have to do something a little custom. can use the “finishes_at” attribute of the timer an subtract now() from that to get the remaining time. however do you need it to update at 1 second granularity? if so, that becomes somewhat challenging as i think the dashboard cards by default update on minute granularity when you use now(). you could hack it by creating a sensor that has the remaining time and updating its state every second. but that’s pretty unadvisable. if you only need minute level granularity, then using the finishes_at attribute as described above could work…

Can you share code for this card?

Here you go, I use an Auto-Entities card to show all the timers running

type: custom:auto-entities
card:
  type: entities
  title: Timers
  show_header_toggle: false
  state_color: true
filter:
  exclude:
    - state: idle
    - attributes:
        current: '= 0'
  include:
    - domain: timer
show_empty: true
sort:
  ignore_case: true
  method: last_triggered
  numeric: false

Which display which timers are running
