Chevy volt automation

Third party integrations
1

I have a Chevy volt. I don’t need a full charge every night to get to work, where they provide a charger on their dime. I’d like to make an automation that would send me a message when charge gets above 33 miles of driving distance estimated, so I could decide whether to unplug it or not. I tried a quick automation to notify me when charge was about 33 miles on the “guessometer” with Automation Editor, but it didn’t fire. Does anyone have any idea how to fix? Thanks!

  alias: Volt charging
  trigger:
  - above: '33'
    entity_id: sensor.mychevy_2017_chevrolet_volt_electric_range
    platform: numeric_state
  condition: []
  action:
  - data:
      message: unplug volt
    service: notify.ios_bretts_iphone

The sensor state is probably a string value so the numeric_state won’t work.
Use a template trigger instead.

trigger:
    - platform: template
      value_template: "{{ states('sensor.mychevy_2017_chevrolet_volt_electric_range') | float > 33 }}"

Worked a charm. Thanks!
