Hello!
I am trying to create a sensor based off of a Datetime Helper but I am getting invalid config errors. My code is:
- sensor:
- Name: Manually Set Wake Up
unique_id: manually_set_wake_up_test
state: "{{ states('input_datetime.shacharit)|as_datetime - timedelta(hours = 1)}}"
device_class: timestame
Thank you in Advance!
Please also share the full error.
Based on the snippet I guess it must be the capitalized Name key that should be fully lowercase.
Other things could be an incorrect indentation due to includes or placement in the correct file (we cannot see in the snippet).
Your example is missing a single quote after the word shacharit and timestamp is misspelled. In addition it should ideally report the date and time in ISO format in order to meet the needs of a timestamp sensor.
- sensor:
- Name: Manually Set Wake Up
unique_id: manually_set_wake_up_test
state: "{{ (states('input_datetime.shacharit')|as_datetime - timedelta(hours = 1)).isoformat() }}"
device_class: timestamp
Be advised that if the value of input_datetime.shacharit is just a time with no date then the template you created will not work.
If it only reports time, use this version:
- sensor:
- Name: Manually Set Wake Up
unique_id: manually_set_wake_up_test
state: "{{ (today_at(states('input_datetime.shacharit')) - timedelta(hours = 1)).isoformat() }}"
device_class: timestamp
@123 @basbrus
Adding @123 's recommended time only code caused a whole lot of errors in my other template sensors as well.

ValueError: Template error: as_timestamp got invalid input 'unknown' when rendering template '= {% set time = as_timestamp(states('sensor.jewish_calendar_
The error messages refer to templates that aren’t in the example I posted above.
For example:
float got invalid input ‘None’ when rendering template
‘{{ state_attr(‘weather.forecast_home_celsius_met’, ‘temperature’) | float }}’
but no default was specified.
Here’s proof that the suggested template works properly. The Input Datetime’s value is 07:00:00 and the template subtracts one hour and reports it as a valid datetime string in ISO format.
If you want to display it as 06:00:00 and not as an ISO datetime string, then you can’t declare its device_class is timestamp.
Sorry, I didn’t think that my question was clear. Why do these errors for other template sensors only show up if I have the code for this sensor in my Yaml?
I removed the device class and the sensor is still not showing in my entities. Any idea why this is happening?
There’s a very good chance that all your other errors are impacting the loading of additional template entities. Fix your errors, you have many.
I cleared up my errors and now I am trying to get back to this. I want the end format to be 9:15. when I use today_at the end result is not the format I want but it does subtract an hour. I tried removing the today_at but i am unable to get the timedelta to work. Any recommendations?
The error: TypeError: unsupported operand type(s) for -: ‘str’ and 'datetime.timedelta
code:
{{ states('input_datetime.shacharit') - timedelta(hours = 1) }}
Don’t remove today_at().
Without it you’re not converting the Input Datetime’s value from string to datetime. That’s why you got that error message.
That’s definitely invalid for a timestamp sensor so your original decision to include device_class: timestamp was a mistake.
Try this version:
- sensor:
- name: Manually Set Wake Up
unique_id: manually_set_wake_up_test
state: "{{ (today_at(states('input_datetime.shacharit')) - timedelta(hours = 1)).strftime('%-I:%M') }}"
thank you! that did the trick. can you please explain what the today_at() does?
Thank you again!
