[Bug]: Template not rendering in template card

Current Behavior

The template doesn’t consistently render. It usually just shows the template text itself.

Expected Behavior

The template renders to show 0 guest devices connected, 1 guest device connected or X guest devices connected.

Steps To Reproduce

type: custom:mushroom-template-card
primary: guest_ssid
secondary: >-
  password

  {% set dev_count = states.device_tracker | selectattr('state', 'eq', 'home') |
  selectattr('attributes.essid', 'eq', "guest_ssid") | list | count %}{% if
  dev_count == 1 %}{{dev_count}} guest device connected{% else %}{{dev_count}}
  guest devices connected{% endif %}
icon: mdi:wifi-lock
multiline_secondary: true

• Set up a template card using this YAML (YAML not necessary, just easier to share).

Environment

• OS: macOS 12.3.1
• Browser: Safari 15.4 / Home Assistant Companion App for macOS / Chrome 102.0.5005.61
• Version: v1.9.0 (HACS)
• Hassio: 2022.6.3
• Template attributes from: UniFi Network

It doesn’t really matter what I use. Not been able to find a match between when it does render and when it doesn’t though.

Anything else?

~Just to close the loop, this is the cursed thing I’ve had to produce to make sure it works 😂~

It did not work…

{% set devices = [] %}
{% for entity in states.device_tracker %}
  {% if 'essid' in entity['attributes'].keys() %}
    {% if 'guest_ssid' in entity['attributes'].values() %}
      {% set devices = devices + [entity] %}
    {% endif %}
  {% endif %}
{% endfor %}

{% set dev_count = devices | list | count  %} 


{% if dev_count == 1 %}
  {{dev_count}} guest device connected
{% else %}
  {{dev_count}} guest devices connected
{% endif %}

Lol nor am I unfortunately. I think it’s because device_tracker doesn’t exclusively cover the UniFi entities so it might be something about whether it comes across a UniFi entity first or not. Will have a play!

Cheers and sorry again 😊
