Why does the notify portion of the automation not work?

Configuration
1

The automation to turn the switch on seems to be working, but the notifier never trips. What is wrong here?

Thanks Matt

Have you tried enabling debug for your sms-component? Also, what happens if you use this instead?

  alias: 'Basement heat on if below 5F'
  initial_state: true
  trigger:
    platform: numeric_state

Your actions don’t look indented correctly to me…

  action:
    - service: switch.turn_on
      data:
        entity_id: switch.basement_heater
    - service: notify.sms_matt
      data:
        title: "Basement heat on"
