    prometheus_url: http://localhost:9090
    prometheus_query: temperature{job="cfrt",location=~"Pisa Fac Agraria.*",province="PI",region="Toscana"}
    unit_of_measurement: "°C"
    platform: prometheus_query
    name: "Temperature Cecina"
    unique_id: "tempCecina"
    prometheus_url: http://localhost:9090
    prometheus_query: temperature{job="cfrt",location=~"Cecina.*",province="LI",region="Toscana"}
