Error with template coding

stevo92 · February 10, 2024, 9:06pm

Hi All.

Can somebody please help me, I’ve quite recently started encountering my home assistant crashing and rebooting and in the error log I have this:

Any help appreciated thanks.

Disable automation or template and see will it reboot.
If it stop reboot than post it here, some will be able to help you with templating.

stevo92 · February 10, 2024, 9:39pm

It reboots fine it just randomly happens after a short period of time of being on the app

ddaniel · February 10, 2024, 9:43pm

Maybe you have some hardware issue. I replaced my working server for i7 processor, 1 gen. And it started to crash and rebooting.
Going back to my old server everything was working fine. No more crashed no more reboots. I couldn’t find anything in the logs that make sense.

Hi @stevo92

I doubt that this route is the cause of your crash. However, if you post the Jinja code that causes this we can take a look.

LiQuid_cOOled · February 11, 2024, 6:35am

Try replacing entity with the actual device or config.entity. I recently struggled with this errors as well.

{{ state_attr(config.entity, 'distance') | round(1) }}
or
like this with your entity and attribute.

{{ state_attr('media_player.emby_shield', 'media_position') | round(1) }}

Although looking at your logs the errors shouldn’t be linked to your crashed. Let us know.

stevo92 · February 11, 2024, 10:54am

              primary: >-
                {{ states(entity) }} {{ state_attr(entity,
                'unit_of_measurement') }}
              secondary: '{{ state_attr(entity, ''distance'') | round(1) | float(0) }} Mi'

I

Is one of the pieces of code that crashes, only recently added float(0) to try to fix the issue .

LiQuid_cOOled · February 11, 2024, 10:56am

float or int. After some advice I avoid round.

templeton_nash · February 11, 2024, 11:05am

Should you have two single quotes each side of distance?

LiQuid_cOOled · February 11, 2024, 11:09am

Probably happened with a cut and paste or populated because double quotes weren’t used, but good catch! There is a random I in the left corner too.

stevo92 · February 11, 2024, 11:19am

Thanks for advice guys, changed it to a double quote, taken the round (0) out and the “I” was actually added by me when pasting here sorry lol

Is what I get now

Supply round(1) with a default.

{{ state_attr(entity, 'distance') | round(1, 0) }}

LiQuid_cOOled · February 11, 2024, 11:33am

That is really good to know!!

LiQuid_cOOled · February 11, 2024, 11:36am

Please post your full code, I’m still seeing multiple typos

{{ state_attr(entity, 'distance') | round(1, ) }} km) renders=2>
({{ state_attr(entity, "distance") | round(1, 0) }} Mi) renders=166>

petro · February 11, 2024, 12:08pm

You missed one. Look at the template in the error, notice it’s missing the default.

change this to

this
{{ state_attr(entity, "distance") | round(1, 0) }}

You missed a set of double quotes

stevo92 · February 11, 2024, 12:39pm

Fixed that thanks, sadly still throwing same errors
