Been wracking my head for the last little while on this one: " expected float for dictionary value @ data['value'] "

Tags: #<Tag:0x00007f73988502d8> #<Tag:0x00007f7398850008>

I’ve tried this code a few different ways but always end up back with the error
Failed to call input_number/set_value. expected float for dictionary value @ data['value']

The Lovelace card that triggers it without the intended function of changing the value:

type: 'custom:button-card'
icon: 'mdi:home'
  action: call-service
  service: input_number.set_value
    entity_id: input_number.mainroom_brightness
    value: '{{ states.input_number.apartment_brightness.state | float }}'

Any thoughts on what I must be missing would be appreciated. I’ve already tried using value: "{{ states('input_number.apartment_brightness') | float }}" instead to no avail. Also tried to pre-convert the state of the input_number to float in a template sensor. Really not sure what else to do and this particular error doesn’t have too much come up when you Google it.

Any help would be appreciated!

You can’t use templates in Lovelace cards without one of the custom template cards.


You can’t template lovelace fields.

Aah, thank you both. I knew it had to be something simple like that that I was missing.
