Template Error/ TemplateSyntaxError/ UI

[Chrissi28]

Hello all,
I’m currently facing a problem that I can’t get solved no matter what approach I take.
Since the latest Home Assistant update (2023.9.3) I get the error message below.

Even if I remove my templats in the UI ( Mushroom Template Card) as well as in the Automation the following error still comes up.
The way the code is just presented in the error report here, it is not written anywhere.
You can find the original code below the bug report.
At the end you will find a picture, what the code does.
(Convert the battery voltage into a percentage value and change the symbol and color, based on the battery voltage).
Batter overview, turns red as soon as a battery voltage has fallen below the limit value and the name of the device is displayed, where the battery must be replaced.

Can you help me here how I can counteract the problem?
Also, I can’t get into the specified file path even via MobaExtrem, which is further annoying me.

I am more than grateful for any help.

The issue is that you have not provided default values for your float filters. On restart all of those templates are trying to mathematically compare a string to a float or subtract a string from an integer, both of which are nonsense.

Updating Templates with the new default values in 2021.10.x

I keep seeing the same question about the new default argument for the templating. This post will cover all possible ways to define default. All the methods that were changed: acos as_timestamp asin atan atan2 cos float log round sin sqrt strptime tan timestamp_custom timestamp_local timestamp_utc Each of them have the exact same default functionality but a different number of arguments. There are multiple ways to use these functions, and this is where all the confusion lies. Understandi…

Hey thanks for your help, but I’m giving up on the template… I am now facing the problem that I have deleted all the templates, booted the system, but the error persists…
I can’t explain it to myself.

[Didgeridrew]

Have you set up any template sensors through the Helpers menu?

[Chrissi28]

No, I have now checked it 10 times, neither Helper nor Automation, nor Config.yaml.

[jorge.lanita (Jocamané)]

i have the same problem.
I even put float(1) and the log shows an error for float(
