Trigger on input_text change

When a string changes I want to trigger an automation.

platform: numeric_state
entity_id: input_text.uart_text
value_template: '{{ is_state(''input_text.help_text'' != states(''input_text.help_text'' }}'

This errors out.

Numeric_state isn’t going to work well if it’s an input text.

Use a state trigger on the entity and leave to and from empty

That works… Thank you.
