As I’ve played over the years I’ve added a bunch of HACs front end modules. Now my “resources” tab has a lot of items, some i use on my main dashboard, some I don’t.
Does HA do lazy loading of these resources or should I clear them up? I.e. I have the sankey energy element from hacs. I don’t have it on my main dashboard and while I’m sitll messing around with it, I’m curious if the fact that it’s listed as a “resource” on my main dashboard is adding any time to the load.
Not saying my load time is super slow (it’s slower on mobile than on my computer), but I would just like to have as fast of an experience as possible for my family on their phones.
Also, is it just ok to remove the resource from that dashboard? when I do so, it mentions “deleting” it and I assume that just means from the dashboard, but was just cuious.
Edit: items behind conditionals appear to lazy-load, that is, they don’t affect the time to first action. I tested this as follows. I reloaded my dashboard a bunch of times, tracking the Largest Contentful Paint (LCP) in chrome. I have 16 large cards hidden behind conditionals. LCP was 1.3 seconds +/- .1. Then I removed the 16 large cards (most of which have at least 15 entities and a few have 30+ entities, several with auto-entity cards which check all entities for qualification) and LCP fell to ~0.9 seconds, faster but not much faster for a page that is maybe 10% of the previous page.
I do think custom:auto-entities is pretty slow but I find it hugely valuable for two reasons. First, lists like “low batteries” are themselves valuable – rather than get a notification, I have a list of batteries below 50% and fix these when it is convenient. Second, I add switches to my home automation and they just show up, no need to look up their entity_id. Another use case is a list of doors and windows open. No notification but right there on my dashboard.
Personally, I like one dashboard that does everything and shows me all the information I might want, rather than a million notifications. Conditionals do seem to accomplish lazy-loading.
The conditional cards do not at least.
The difference you see is in the rendering time and not the load time.
The rendering time is the time the client use to actually draw the visible elements.
There have been several issues over time that shows this, like elements in the conditional cards affecting other cards even when hidden.
