Hi, I’m struggling with two errors of the following template sensor:
differenz_humidity_garage:
friendly_name: "Differenz Luftfeuchte"
unit_of_measurement: "g/m³"
device_class: humidity
icon_template: mdi:water
value_template: "{{ ((states('sensor.garage_absolute_humidity') | float) - (states('sensor.aussensensor_absolute_humidity') | float))|round(2) }}"
HA is giving back these two errors:
TemplateError(‘ValueError: Template error: float got invalid input ‘unknown’ when rendering template ‘{{ ((states(‘sensor.garage_absolute_humidity’) | float) - (states(‘sensor.aussensensor_absolute_humidity’) | float))|round(2) }}’ but no default was specified’) while processing template ‘Template<template=({{ ((states(‘sensor.garage_absolute_humidity’) | float) - (states(‘sensor.aussensensor_absolute_humidity’) | float))|round(2) }}) renders=4>’ for attribute ‘_attr_native_value’ in entity ‘sensor.differenz_humidity_garage’
and
Error while processing template: Template<template=({{ ((states(‘sensor.garage_absolute_humidity’) | float) - (states(‘sensor.aussensensor_absolute_humidity’) | float))|round(2) }}) renders=2>
Any hint would be appreciated!
