Lightning Strike Alarm for Outdoor Swimming Pool

This is a fun project I worked on.

If there is lightning within 10 miles detected by my Tempest Weather Station (and near by sensors), it will send a SMS notification and also play an audible alert in my outdoor space.

alias: "Safety: Lightning Strike"

trigger:
  - platform: state
    entity_id:
      - sensor.weatherflow_last_lightning_strike

        states('sensor.weatherflow_last_lightning_strike_distance') }} miles.
        Please stop outdoor activities and seek shelter until at least 30
        minutes after the most recent strike, which is currently {{

The safer thing to do is to install a lightning bolt arrestor somewhere tall and away from the pool, connected to ground.

Have that also, but it’s still safer to be inside and not in the pool during a storm.
