[Bug]: Template not rendering in template card
caraar12345 opened this issue · comments
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?
Hello 🙂 It's an error with your template. You can test it here.

Hmmm ... that's entirely what I would have expected. But for some reason, it fails in the template tester, but not always in the Template Card !!??
Regardless, doesn't seem to be a Mushroom thing. Thank you anyway 🙏
Maybe you must check if the attribute exist before selectattr? I'm not a Jinja template expert 😅
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 😊
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 %}
