ValueError: Template error: strptime got invalid input 'unknown' when rendering template (not the first time asked :) )

Configuration
1

Hello,

Not the first time asked, but I can’t find the solution of my problems.
I have several HP templates and changed it to the new template way.
But still having errors in my log. Can somebody help me?

Welcome back, after four years! :+1:

You’re missing the default value in your strptime. :slight_smile:

In this line

{{ ((as_timestamp(strptime(states('sensor.hp_officejet_8020_next_renewal_date'), '%Y-%m-%d'))|int(0) - as_timestamp(strptime(states('sensor.date'), '%Y-%m-%d'))|int(0) ) / 86400)|int(0) }}

add a default value of your choice for both strptime and the error should be gone.

Hi Patrick,

Had long time no issues :slight_smile:
But still struggling with this. I know the problem, but don’t now where to put and in what format the defaults. I was searching a lot, but can you explain what and where in a different template below.

I found an other sulution for the earlier fault. Can’t found the place where I must put the defaults you told me.

Regard,
Raimond
