Entities Card and external URL from attribute

[Tomahawk]

Is it possible to pick up a URL from an attribute and use it in the Entities Card?

entities:
  - type: weblink
    url: "{{state_attr('sensor.opentx_multiprotocol', 'latest_release_url') }}" # DOES not work!
    name: Latest Multiprotocol release
  - type: weblink
    name: Home Assistant Forum
    url: 'https://community.home-assistant.io'
    icon: 'mdi:comment-multiple-outline'
show_header_toggle: false
title: 'RC: Jumber T16 Pro OS'
type: entities

Create weblink from entity attribute?

Can I create a weblink from an entity attribute value? e.g. device tracker entity device_tracker.ha_nas: source_type: router hostname: office/ha-nas-3212 name: HA / NAS oui: Espressi ip: 192.168.2.141 [...] friendly_name: HA / NAS it’s a tasmota smart plug, and I want to convert device_tracker.ha_nas[ip] into a weblink: type: entities entities: - type: weblink name: Web Console url: 'http://{{ ip address here }}/'

Set Weblink URL attribute to another sensor's value?

I’ve got a file on a network share that contains a single URL wrapped in quotes and is mapped to the sensor.file device. My goal is to set a weblink button on my UI that will link this URL, but I can’t seem to figure out how to set it. I’ve tried variation of templates and config like below with no luck. Hoping someone can point me in the right direction. Thanks! weblink: entities: - name: Cross_Link url: '{{ states.sensor.file }}'

And I still haven’t found a proper solution.

The only workaround is, to add a markdown card with the link in it.
