Hey Home Assistant, turn off solar panels when the price is negative

This is something I have started using in my Home Assistant as Automation. When the price is below 1ct, I just turn off my solar invertor (which I've added a "switch" entity to). The yaml:

alias: Tibber Below Low price
description: Turns off the inverter if the price is too low
  - platform: numeric_state
      - sensor.electricity_price_thuis
    below: 1
condition: []
  - service: notify.mobile_app_iphone_s_matej
    metadata: {}
      message: (BELOW) Price {{trigger.to_state.state}}
  - service: switch.turn_off
    metadata: {}
    data: {}
      entity_id: switch.inverter_switch
mode: single

Of course, don't forget to turn it back on when the price is above 1ct with an inverted automation ;)

This is how it looks like
