Trigger on Value Change to Positive Value

Configuration

Does anyone have any idea how I could make a template to detect if a sensor number switches from 0 to anything positive or negative to anything positive?

I ended up using this;

  - condition: template
    value_template: "{{ (trigger.from_state.state | float <0) }}"
   - condition: and
     conditions:
       - condition: template
         value_template: "{{ (trigger.to_state.state | float >0) }}"

alias: example
trigger:
  - platform: state
    entity_id: sensor.whatever
condition:
  - condition: template
    value_template: >
      {{ trigger.from_state.state | float(0) <= 0 and trigger.to_state.state | float(0) > 0 }}
action:
  ... etc ...
