Release with the issue: 1.3.6

Last working release (if known):

Browser and Operating System: Firefox, Brave @ Windows 11 Pro

Description of problem:

Javascript errors shown in the web inspector (if applicable):

I have the following template card:

  - type: 'custom:config-template-card'
    variables:
      number: 14
      timeStamp: states['sensor.vpnclients'].attributes.lastUpdated
    entities:
      - sensor.vpnclients
    card:
      type: custom:list-card
      entity: sensor.vpnclients
      title: "${ vars['timeStamp'] }"
      feed_attribute: clients
      columns:

It works correctly as you can see it here. However, in the title of the card I would like to:

1. convert the time to a specific format. So far I tried this:

as_timestamp(states['sensor.vpnclients'].attributes.lastUpdated) | timestamp_custom('%m %d - %H:%M')

and this:

states['sensor.vpnclients'].attributes.lastUpdated | as_timestamp | timestamp_custom('%m %d - %H:%M')

both resulting in the whole card being not rendered at all. Note, both work OK in the Template editor within HA. 2. add some extra text, so that the result will be something like this:

Connected clients at 15:00

I tried this the following way:

title: "Connected clients at ${ vars['timeStamp'] }"

Again, the result is that the whole card is gone. Additional information: Here is the console log from FF:

+1 Trying to convert a timestamp to local datetime with no success using the following:

{{as_local(as_datetime(states.sensor.s20_kaue_last_reboot.state))}}

Templates are JS. You are trying to use jinjia2 templates! Rewrite your templates to JS then.

title: "Connected clients at ${ vars[...] }"

Wrong. Must be:

title: '${ "Connected clients at " + vars[...] }'

title: "${ vars['timeStamp'] }"

Try just this:

title: '${ timeStamp }'
