Best way to have a Jinja2 Template spit out multi-line?

[matthewcbyington]

Hey there,

I have chores that I keep track of with input numbers. There’s a threshold (30) that once they reach that, I need to do them. Examples are changing the HVAC filters, etc. Each one increments by 1 if it needs to be done once a month or 0.5 for example if I need to do it every 2 months.

The following template spits out the chores I need to do.

I want to have it organized better where each chore is on a newline. I’m sure this is something simple, but when I do this, and this template basically writes to a text helper that I show on a Dashboard, it’s all wonky and there’s a lot of weird spacing. I’m sure I’m missing something.

Thanks!

You could put the template into a Markdown card and get more control over the result’s appearance (including the ability to employ newlines and HTML codes).

The following example displays the results in a table:

Display recently triggered automations

Goal Display a list (in the UI) of all automations, sorted by last_triggered in reverse-chronological order (i.e. the most recently triggered automation appears first). Each row should display the automation’s name and the elapsed time since it was triggered (showing days, hours, and minutes). Previous Solution In the past I used the Auto-Entities Card to easily achieve the goal. A minor drawback is that the appearance is a bit cluttered because each row also shows an automation icon and a to…

Newlines does not work well with htm, but
is good

I know it works, but it can be a bit erratic, like not allowing double newlines without extra characters in between and value or code delimiters can also make strange things happen, if they are not pre-/suffix with a -.

@WallyR

like not allowing double newlines without extra characters in between

Instead of making easily disproved claims, post an example demonstrating “a bit erratic”.

EDIT

Or did you mean it disallows triple newlines (or more)? Because in that case, you’re correct; the Markdown card won’t render more than two consecutive \n.

I have actually never really tested how many it allowed.
I just ran into the issue with newlines and having {{ }} be counted in too, so tried to use {{- -}}, but in the end it got too confusing on the card I made.
