Hi
Does anyone know why I keep getting the error below?
I added the availability line but the error stays
- name: "Solax Local AC Frequency"
unique_id: solax_local_ac_frequency
state: >-
{{ state_attr('sensor.solax_local', 'Data')[50] | float(0) }}
unit_of_measurement: "Hz"
device_class: frequency
icon: mdi:music-clef-treble
availability: "{{ state_attr('sensor.solax_local', 'Data')[50] is not none }}"
* TemplateError('UndefinedError: None has no element 50') while processing template 'Template<template=({{ state_attr('sensor.solax_local', 'Data')[50] | float }}) renders=4>' for attribute '_attr_native_value' in entity 'sensor.solax_local_ac_frequency'
when I execute the availability line in the template editor, the result is: “True” so it looks correct?!
