Jinja2 templates will spam network requests.

[bratanon]

When using the jinja2 template, this card will request the template endpoint multiple times every second.

  - entity: light.entrance_outdoor    
    type: "custom:secondaryinfo-entity-row"
    secondary_info: "{{ 1 + 1 }}"

Guess this is because _updateElement will trigger as soon as something changes in the hass object, which for a larger setup could be many hundred times per second.

Yep, I noticed the same while looking around for a way to use {entity} inside the Jinja templates. Gave up on opening a new issue, as we'd better get back to the weird [[ ]] syntax, given this seems unavoidable for being present since 2021.

Edit: or maybe not, bdraco seems to have made a suggestion that could fix this issue at #53.
